The electric fuel pump P mentioned above is structured such that the pump bottom portion 12E is arranged so as to face to the bottom plate 11A of the supporting bracket 11 and arranged along the supporting bracket 11, and in this state, is attached to the supporting bracket 11 by a fastening band 12F. Further, a filter F is attached to the fuel suction passage 12C of the electric fuel pump P, a fuel discharge passage 12G of the electric fuel pump P is piped to a strainer S, and clean fuel from which foreign materials are removed by the strainer S is supplied to an engine (not shown) via a discharge pipe 13 provided in the lid body 10 . In this case, a detailed structure of a portion (the portion shown by reference symbol .A in Fig. 3) near the bottom portion of the electric fuel pump P in the fuel supply apparatus mentioned above is shown in Figs. 4 and 5 . Fig. 4 is a vertical cross sectional view of a main portion near the bottom portion of the electric fuel pump, and Fig. 5 is a horizontal cross sectional view in a line B-B in Fig. 4. The vapor bleeding hole 12D is open downward by an opening portion 12Da, in the pump bottom portion 12E of the electric fuel pump P, a partition wall 14 formed substantially in a U shape and protruding downward from the pump bottom portion 12E is provided around the opening portion 12Da, and an opening portion 14A of the partition wall 14 is open sideward. Further, the fuel suction passage 12C protruding downward is provided in the pump bottom portion 12E, and an engagement step portion 12Ca facing downward is provided in an outer periphery of the fuel suction passage 12C. Further, a supporting boss 15 protruding downward is provided in the pump bottom portion 12E, and the supporting boss 15 has an engagement stepportion 15a which is disposed in a side of the fuel suction passage 12C and faces downward. The engagement step portions 12Ca and 15a are formed so that the protruding heights from the pump bottom portion 12E are the same. Reference numeral 16 denotes a rubber plate formed in a thick disc shape and arranged so as to face to the pump bottom portion 12E. The rubber plate 16 is formed in a disc shape which is substantially the same as the shape of the pump bottom portion 12E. Further, a recess portion 16B extending downward from an upper surface 16A of the rubber plate 16 is recessed in this rubber plate 16. The recess portion 16B surrounds an outer periphery of the partition wall 14, and a bottom portion 16Ba of the recess portion 16B is arranged so as to face to the opening portion 12Da of the vapor bleeding hole 12D, and the recess portion 16B is open sideward by an opening portion 16Bb (the opening portion 16Bb of the recess portion 16B and the opening portion 14A of the partition wall 14 are open in the same direction). Further, an escape hole 16D is provided in the rubber plate 16 so as to extend from the upper surface 16A toward a lower surface 16C, and the escape hole 16D is formed in a shape capable of passing the fuel intake passage 12C and the supporting boss 15 through. The filter F is formed by a fuel flow passage boss 17 inserted to a outer periphery of the fuel suction passage 12C and a mesh-like filter portion (not shown) . A collar portion 17A extending sideward is formed in an upper end of the fuel flow passage boss 17, and a filter mounting hole 17B ispierced in the collarportion 17A. Further, the bottom plate 11A formed so as to be bent in a horizontal direction from a lower end of the supporting bracket 11 is formed in a shape facing substantially the whole of the pump bottom portion 12E of the electric fuel pump P, and an escape hole 11Aa capable of passing at least the fuel suction passage 12C through is formed in the bottom plate 11A. Further, the electric fuel pump P is mounted to the supporting bracket 11 in accordance with the following manner. First, the filter F is attached to the electric fuel pump P. This is achievedby inserting the fuel flowpassage boss 17 of the filter F to the fuel suction passage 12C protruding from the pump bottom portion 12E of the electric fuel pump P, whereby the collar portion 17A is brought into contact with the engagement step portion 12Ca of the fuel flow passage boss 17 and the engagement step portion 15a of the supporting boss 15, and at this time, the filter mounting hole 17B of the collar portion 17A is inserted to and arranged in the supporting boss 15 . Then, in this state, a push nut 18 is arranged so as to be fitted toward the supporting boss 15, whereby the filter F is attached to the electric fuel pump P. Next, the rubber plate 16 is attached toward the pump bottom portion 12E of the electric pump P. That is, an escape hole 16Da of the rubber plate 16 passes the fuel flow passage boss 17 of the filter F, the fuel suction passage 12C and the outer periphery of the supporting boss 15 through, and the upper surface 16A of the rubber plate 16 is brought into contact with the pump bottom portion 12E. On the other hand, the recess portion 16B open toward the upper surface 16A of the rubber plate 16 is arranged so as to surround the outer periphery of the partition wall 14 protruding from the pump bottom portion 12E, and at this time, the bottom portion 16Ba of the recess portion 16B closes the lower opening of the partition wall 14 and is arranged so as to face to the opening portion 12Da of the vapor bleeding hole 12D. Accordingly, the filter F and the rubber plate 16 are arranged in the pump bottom portion 12E of the electric fuel pump P, the lower surface 16C of the rubber plate 16 is arranged on the bottom plate 11A of the supporting bracket 11 in this state, and the electric fuel pump P is fastened to the supporting bracket 11 by the fastening band 12F after being set to this state. In accordance with the conventional fuel supply apparatus of the vehicle, when the supporting bracket 11 or the electric fuel pump P vibrates under operation of the engine or under operation of the electric fuel pump , a vibration in a vertical direction of the electric fuel pump P is absorbed by the rubber plate 16. Further, the impeller 12B rotates within the pump chamber 12A, whereby the vapor is generated within the pump chamber 12A. The vapor is discharged toward the exterior from the opening portion 12Da of the vapor bleeding hole 12D together with a part of the fuel which is pressure increased within the pump chamber 12A, and the fuel containing the vapor once collides against the bottom portion 16Ba of the recess portion 16B in the rubber plate 16, thereafter changes its flowing direction sideward, and is discharged side ward from the opening portion 14A of the partition wall 14. Accordingly, the pressure increased fuel containing the vapor does not collide against the filtering portion of the filter F to break or deform the filtering portion. In accordance with the conventional fuel supply apparatus mentioned above, since the recess portion 16B surrounding the partition wall 14 and facing to the vapor bleeding hole 12D is required in the rubber plate 16, it is necessary to form the rubber plate 16 in a shape covering substantially the whole of the pump bottom portion 12E in the electric fuel pump P. Accordingly, a diameter of the rubber plate 16 is increased, and it is impossible to achieve a reduction in cost of the parts. That is, when the diameter of the rubber plate 16 is increased, a metal mold of the rubber plate 16 becomes expensive and a material cost is increased. In particular, in the case that the gasoline fuel containing an alcohol is used, it is necessary to use a rubber material containing a fluorine, whereby an increase of the material cost is significantly large. Further, the fuel injected from the opening portion 12Da of the vapor bleeding hole 12D directly collides against the bottom portion 16Ba of the recess portion 16B in the rubber plate 16, and a deterioration of the rubber is promoted. Accordingly, this is not preferabie. Further, since the shape of the bottom plate 11A supporting one side of the rubber plate 16 is increased due to a large diameter of the rubber plate 16, the weight of the supporting bracket 11 is increased. SUMMARY OF THE INVENTION A fuel supply apparatus of a vehicle in accordance with the present invention is made by taking the problems mentioned above into consideration, and a main object of the present invention is to provide a fuel supply apparatus of a vehicle which can achieve a function of absorbing vibration between an electric fuel pump and a supporting bracket and a function of changing sideward a fuel flow containing vapor discharged from a vapor bleeding hole by a compact and inexpensive structure. In order to achieve the object mentioned above, in accordance with the present invention, there is provided a fuel supply apparatus of a vehicle comprising : a lid body closing an opening portion of a fuel tank; a wesco type electrical fuel pump in which a pump bottom portion is arranged so as to face to a bottom plate of a supporting bracket fixed to the lid body, and a fuel suction passage connected to a pump chamber and a vapor bleeding hole are open to the pump bottom portion, and which is attached to the supporting bracket; and a filter connected to the fuel suction passage of the electric fuel pump, wherein the fuel supply apparatus is characterized in that the filter is provided with a fuel flow passage boss inserted to and arranged in the fuel suction passage, and a collar portion extending sideward from the upper end of the fuel flow passage boss, the collar portion is provided with a filter mounting hole and a vapor bleeding hole opposing surface portion, the filter is attached to the electric fuel pump by arranging the fuel flow passage boss of the filter so as to insert to the fuel suction passage of the electric fuel pump, arranging the filter mounting hole so as to insert to a supporting boss protruding downward from the pump bottom portion, arranging the vapor bleeding hole opposing surface portion so as to oppose to an opening portion of the vapor bleeding hole, and fitting a push nut to the supporting boss protruding from the filter mounting hole of the collar portion, an insulator mounting hole is pierced in the bottom plate of the supporting bracket, a tubular insulator made of an elastic member is arranged so as to be inserted to the insulator mounting hole, and the insulator is arranged between the bottom plate of the supporting bracket and the pump bottom portion of the electric fuel pump. In accordance with the fuel supply apparatus of the vehicle in the present invention, the filter can be attached to the electric fuel pump by inserting the filter mounting hole pierced in the collar portion to the supporting boss and thereafter fitting the push nut to the supporting boss. Further, since the vapor bleeding hole opposing surface portion provided in the collar portion of the filter is arranged so as to oppose to the opening portion of the vapor bleeding hole, it is possible to make the fuel containing the vapor discharged from the opening portion of the vapor bleeding hole collide against the vapor bleeding hole opposing surface portion so as to change the flowing direction of the fuel sideward. Further, since the function of converting the fuel flow containing the vapor discharged from the opening portion of the vapor bleeding hole into the side direction flow is provided in the vapor bleeding hole opposing surface portion of the filter, it is possible to make the shape of the insulator more compact than the rubber material arranged between the pump bottom portion of the electric fuel pump and the supporting bracket, and it is further possible to make the bottom plate of the supporting bracket corresponding to another end of the insulator compact.

DESCRIPTION OF THE PREFERRED EMBODIMENT A description will be given below of one embodiment of a fuel supply apparatus of a vehicle in accordance with the present invention with reference to Figs. 1 and 2 . Fig. 1 is a vertical cross sectional view of a main portion near a bottom portion of an electric fuel pump attached to a supporting bracket, and Fig. 2 is a horizontal cross sectional view along a line C-C in Fig . 1 . In this case, since the same structure as the conventional one is used for an electric fuel pump P, the same reference symbols are attached, and a description thereof will be omitted. A filter F has a fuel flow passage boss 1 arranged so as to be inserted to a fuel suction passage 12C, is provided with a filtering portion (not shown) filtering the fuel in a lower portion of the fuel flow passage boss 1, and is provided with a flat collar portion 1A in the upper end of the fuel flow passage boss 1 . The collar portion 1A has a filter mounting hole 1B and a vapor bleeding hole opposing surface portion 1C, and the filter mounting hole 1B is pierced so as to pass through the collar portion 1A and is inserted to a supporting boss 15 protruding from a pump bottom portion 12E. Further, the vapor bleeding hole opposing surface portion 1C is formed in a shape closing a lower opening of a U-shaped partition wall 14 open downward from the pump bottom portion 12E. Reference numeral 2 denotes a tubular insulator made of a rubber material. The tubular insulator 2 is constituted by a large diameter portion 2A and a small diameter portion 2B. Among them, the large diameter portion 2A is formed in a shape partly facing to the pump bottom portion 12E and is formed in a cylindrical shape or a rectangular column shape, and the small diameter portion 2B is formed in a cylindrical shape. For example, a diameter of the large diameter portion 2A is 10 mm, and a diameter of the small diameter portion 2B is 4 mm (however, the diameters are not limited to these numerals). The upper end of the supporting bracket 3 is fixed to an illustrated lidbody 10, and the lower end thereof is bent sideward, whereby a bottom plate 3A is formed. The bottom plate 3A is formed in a fork shape, faces to a part of the pump bottom portion 12E in the electric fuel pump P, and on which the insulator 2 can be arranged. Further, two insulator mounting holes 3B are pierced on the bottom plate. Then, the filter F is attached to the electric fuel pump P in the following manner. The fuel flow passage boss 1 of the filter F is arranged so as to be inserted to the fuel suction passage 12C, and the upper surface of the collar portion 1A of the filter F is arranged so as to be brought into contact with an engagement step portion 12Ca of the fuel flow passage boss 1 and an engagement step portion 15A of the supporting boss 15. In a contact state of the collar portion 1A, the supporting boss 15 is arranged so as to be inserted to the filter mounting hole 1B, and the vapor bleeding hole opposing surface portion 1C is arranged so as to close a lower opening of the parti tion wall 14 protruding downward from the pump bottom portion 12E. This means that the vapor bleeding hole opposing surface portion 1C is arranged so as to oppose to an opening portion 12Da of a vapor bleeding hole 12D open to the inner side of the partition wall 14. Further, a push nut 18 is arranged so as to be fitted to the supporting boss 15 protruding downward with passing through the collar portion 1A, whereby the filter F is attached toward the pump bottom portion 12E of the electric fuel pump P. On the other hand, the insulator 2 is arranged in the bottom plate 3A of the supporting bracket 3, a small diameter portion 2B of each of two insulators 2 is arrangedsoas tobe insertedto eachof the insulator mounting holes 3B pierced in the bottom plates 3A, whereby the insulator 2 (particularly the large diameter portion 2A) is supported to each of the bottom plates 3A. Then, the electric fuel pump P to which the filter F is attached is mounted to the supporting bracket 3, the pump bottom plate 12E of the electric fuel pump P is arranged so as to face onto the bottom plate 3A, and is fastened to the supporting bracket 3 by a fastening band 12F shown in Fig. 3 in this state. In the fastening state mentioned above, the upper surface of the large diameter portion 2A in the insulator 2 is arranged near the pump bottom portion 12E or arranged in contact therewith. In accordance with the fuel supply apparatus of the present invention having the structure mentioned above, as soon as the electric fuel pump P is driven, the foreign materials are removed from the fuel within the fuel tank T by the filtering portion of the filter F, this fuel is sucked into the pump chamber 12A via the inner side of the fuel flow passage boss 1 and the fuel suction passage 12C, and the fuel which pressure is increased in the pump chamber 12A is supplied to the engine via the fuel discharge passage 12G, the strainer S and the discharge pipe 13. In this case, the vapor generated within the pump chamber 12A is injected downward from the opening portion 12Da of the vapor bleeding hole 12D together with the fuel, and the fuel containing the vapor collides against the vapor bleeding hole opposing surface portion 1C of the filter F, thereafter changes a flow direction thereof outward, and is discharged leftward from the opening portion 14A of the partition wall 14 open leftward. Accordingly, the pressure increased fuel containing the vapor does not collide against the filtering portion arranged below the fuel flow passage boss 1 of the filter F to damage and deform the filtering portion. On the other hand, during the operation of the engine, the electric fuel pump P and the supporting bracket 3 sometimes vibrate, however, a longitudinal vibration of the electric fuel pump P can be absorbed by the insulator 2. In the structure mentioned above, attention will be paid to the following points. That is, the filter mounting hole 1B and the vapor bleeding hole opposing surface portion 1C are provided in the collar portion 1A of the filter F, whereby it is possible to achieve a function of attaching the filter F to the electric fuel pump P and a function of changing the flowing direction of the fuel containing the vapor. Further, since the collar portion 1A provided with the filter mounting hole 1B and the vapor bleeding hole opposing surface portion 1C can be integrally injection molded by using a synthetic resin material at a time of forming the filter F, a manufacturing cost of the filter F is not increased. Further, in the structure mentioned above, since the filter F is provided with the function of changing the flowing direction of the vapor, the insulator 2 is provided only with the vibration proofing function. Accordingly, it is sufficient that the insulator 2 is formed in a shape partly brought into contact with the pump bottom portion 12E, and it is possible to achieve to make the shape of the insulator 2 remarkably compact. Accordingly, even in case of manufacturing the insulator 2 by using an expensive rubber material, the manufacturing cost of the insulator 2 is not largely increased due to a little use amount of the material. Further, since the insulator 2 is made compact in the structure mentioned above, it is possible to make the shape of the bottom plate 3A of the supporting bracket 3 supporting the insulator 2 small, whereby it is possible to largely reduce the weight of the supporting bracket 3 and it is possible to reduce the manufacturing cost of the supporting bracket 3 by the press molding. As described above, in accordance with the fuel supply apparatus of the vehicle of the present invention, the filter is provided with the fuel flow passage boss inserted to and arranged in the fuel suction passage, and the collar portion extending sideward from the upper end of the fuel flow passage boss, the collar portion is provided with the filter mounting hole and the vapor bleeding hole opposing surface portion, the filter is attached to the electric fuel pump by arranging the fuel flow passage boss of the filter so as to insert to the fuel suction passage of the electric fuel pump, arranging the filter mounting hole so as to insert to the supporting boss protruding downward from the pump bottom portion, arranging the vapor bleeding hole opposing surface portion so as to oppose to the opening portion of the vapor bleeding hole, and fitting the push nut to the supporting boss protruding from the filter mounting hole of the collar portion, the insulator mounting hole is pierced in the bottom plate of the supporting bracket, the tubular insulator made of the elastic member is arranges so as to be inserted to the insulator mounting hole, and the insulator is arranged between the bottom plate of the supporting bracket and the pump bottom portion of the electric fuel pump. Accordingly, it is possible to achieve the function of attaching the filter to the electric fuel pump and the function of changing the flow direction of the vapor without making the size of the filter large and increasing the manufacturing cost. Further, since the insulator may be formed in the small shape to be arranged so as to partly face to the pump bottom portion of the electric fuel pump, it is possible to inhibit a wide increase of the manufacturing cost even in case of manufacturing the insulator by the expensive rubber material. Further, since the insulator is made compact, it is possible to make the shape of the bottom plate of the supporting bracket supporting the insulator compact, whereby it is possible to achieve a weight reduction of the whole of the fuel supply apparatus and it is possible to reduce the manufacturing cost of the supporting bracket in accordance with the press molding.
