[Background Art] [0002] In the related art, the upper portion of a rear cushion for suspending a rear wheel is mounted to a pair of body frames provided on both sides of a motorcycle. The upper portion of the rear cushion is fixed to a boss provided on each of the opposing inner sides or outer sides of the body frames (see, for example, Patent Document 1). Also, in some of scooter-type motorcycles, in particular, a storage box is provided between a pair of body frames and under a seat. [Patent Document 1] International Publication No. 200'9/071858 [Disclosure of the Invention] [Problem to be Solved by the Invention] [0003] The above-described storage box is required to provide an enlarged storage space. However, in a case where the upper portion of the rear cushion is fixed onto each of the opposing inner sides of the body frames, the storage space of the storage box disposed between the body frames is reduced to avoid interference with the fixing portion of the rear cushion. Also, it is desired to store a piece of luggage such as an attache case in the storage space in a substantially horizontally laid position. [0004] The present invention has been niade in view of the above-described circumstances, and it is an object of the present invention to provide a storage box STiructure for a motorcycle which iTiinimizes a cecrease in storage space even in a case where the upper portion of a rear cushion is fixed onto the inner sides of body frames, and which allows effective use of the storage space, [Means for Solving the Problem] [0005] To address the above-described problem, according to the present invention, there is provided a storage box structure for a motorcycle, in which a pair of left and right body frames are provided below a seat, a storage box is arranged under the seat and between the pair of body frames, and an upper portion of a cushion for suspending a rear wheel is mounted to one or both of opposing inner side surfaces of the body frames, wherein recesses for avoiding interference with the upper portion of the cushion are provided on both outer sides of the storage box, a first storage space is formed by forming flat surfaces, which are flat in a vehicle's lateral direction, in the recesses and inside the storage box, and a second storage space is formed by forming an inclined surface between the recesses on the left and right. According to this configuration, a piece of luggage such as an attache case can be stored in the first storage space in a _ubstantially horizontally laid position. Also, a long piece of luggage can be stored in the second storage space along the inclined surface. ;0006] Also, the upper portion of the cushion may be mounted to a rear side cf each of the body frames, and the recesses ir.av be provided in a rear side of the storage box. According to this configuration, no constraint is imposed on the space in the front side and at the central portion of the storage box by the recesses. [0007] Further, the inclined surface may be inclined toward a front-side bottom surface of the storage box. According to this configuration, a long piece of luggage can be stored along the inclined surface from the bottom surface of the storage box. [0008] Also, the flat surfaces may be formed at the same height. .According to i:his configuration, the flat side of an attache case or the like can be placed in more intimate contact with the flat surfaces. [0009] Also, the seat may be formed integrally in a stepped shape so as to project upward in its rear portion, a rear portion of a bottom plate of the seat may be raised upward along this seat shape, and the rear portion may be arranged in an upper portion of the first storage space. [Effect of the Invention] [0010] In the storage box structure for a motorcycle according to the present inven-ion, recesses for avoiding interference with the upper portion of the cushion are provided on both outer sides of the storage box, a first storage space is formed by forming flat surfaces, which are flat in a vehicle's lateral direction, in the recesses and inside the storage box, and a second storage space is formed by forming an inclined surface between the recesses on the left and right. Therefore, a piece of luggage such as an attache case can be stored in the first storage space in a horizontally laid state, and effective use of the storage space can be made by optimizing the shape of the recesses. Also, a long piece of luggage can be stored in the second storage space along the inclined space, and a decrease in the storage space of the storage box can be minimized by optimizing the shape of the portion between the recesses. [0011] Also, the upper portion of the cushion is mounted to a rear side cf each of the body frames, and the recesses are provided in a rear side of the storage box. Thus, no constraint is imposed on the space in the front side and at the central portion of the storage box by the recesses. Therefore, it is possible to make effective use of the storage space of the storage box, and convenience is not impaired. [0012] Further, the inclined surface is inclined toward a front-side bottom surface of the storage box. Thus, a long piece of luggage can be stored along the inclined surface from the bottom surface of the storage box. Therefore, effective use of the storage space can be made, thus eliminating the inconvenience of not being able ro fir a long piece of luggage in the storage space even when the recesses are formed. :0C13] Also, the flat: surfaces are formed at the sarrie height, so the flat side of an attache case or the like can be placed in intimate contact wizh the flat surfaces. Therefore, the attache case or the like can be stored in a stable position, thereby enhancing the convenience of storage. [0014] Also, the seat is formed integrally in a stepped shape so as to project upward in its rear portion, a rear portion of a bottom plate of the seat is raised upward along this seat shape, and the rear portion is arranged in an upper portion of the first storage space. Thus, the first storage space can be extended upward to increase the storage volume.

The lower end of the rear cushion unit 27 is mounted to a rear portion of the power unit 13 located under the air cleaner 2. [0028] Fig. 4 is an exploded perspective view illustrating the portion in the vicinity of the occupant seat of the motorcycle according to the present invention. Also, Fig. 5 is a view of the storage box 24 alone as seen from the side, and Fig. 6 is a view of the storage box 24 shown in Fig. 5 as seen in the Z direction. Also, Fig. 7 is a plan view of the storage box as seen from above, showing a state in which a helmet is stored in the storage box, and Fig. 8 is a side view of the same. Fumher, Fig. 9 is a cross-sectional view taken along the line B-E of Fig. 3, showing the relationship beiLween a relief portion 100 of the storage box and ohe head portion of the rear cushion unit 27. [0029] As shown in Fig. 4, the storage box 24 having the opening 2'3k at the top and serving as a storage is arranged between the inner sides of the rear frames 21L, 21R that are opposed to each other. As shown in Figs. 3 and 5, as seen in side view, the storage box 24 has a deep storage space in the front side and a shallow storage space in the rear side. That is, the bottom surface of the storage box 24 is gently inclined diagonally upward from its front end portion 24a toward the rear side {hereinafter, referred to as the bottom surface 24A) and then steeply inclined diagonally upward to the rear so as to avoid interference with the rear wheel 41 that swings vertically (hereinafter, referred to the bottom surface 24B), and further extends diagonally upward to the rear at an inclination that is more gentle ohan that of the bottom surface 24B (hereinafter, referred to as the bottom surface 24C}. The shapes of the bottom surfaces 24A, 24B, 24C are so determined as to make the srorage space as large as possible while avoiding interference with the air cleaner 2, the throttle body 3, the rear cushion unit 27, and the rear wheel 41 that swings vertically described above. Also, as shown in Fig. 6, as seen in top view, the outer side surface and opening 24k of the storage box 24 are extended to the fullest extent so as to take up the whole inside dimension between the rear frames 21L, 21R that are opposed to each other. along the shape of the central portion of the rear frames 21L, 21R bulging in the width direction of rhe vehicle body. [003G] 'n this way, the storage box 24 is formed so as to make its storage volume as large as possible while avoiding interference with parts inside the vehicle body. Also, as shown in Fig. 1, -he front end portion 24a of ::he storage box arranged inside the vehicle body in this way is located at the portion of che third cross frame 22, and the rear end portion chereof is located at the portion of a grab rail 68. [0031] As shown in Figs. 4 and 5, the storage box 24 is provided wiih horizontal flanges 75L, 75R, rear mounring portions SOL, 80R, and front mounting portions 81L, SIR which are used for mounting the storage box 24 to the body frame 11. The horizontal flanges 75L, 75R are mounted to the storage-box supporting brackets 25L, 25R described above, the rear mounting portions SOL, 80R are mounted to the mounting bracket 29, and the front mounting portions 81L, SIR are mounted to the mounting brackets 30L, 30R. The horizontal flanges 75L, 75R, the rear mounting portions SOL, 80R, and the front mounting portions SIL, SIR are each mounted by means of a fastening member such as a belt not shown. [0032] As shown in Figs. 1 and 4, above the storage box 24, the occupant seat 52 is mounted so as to cover the opening 24k of the storage box 2^5 from above in such a way as to allow opening and closing of the opening 24k. The occupant seat 52 is formed in a stepped shape such -hat a rear seat portion 52R on which the pillion passenger is sealed is one step higher than a front seat portion 52F on which the rider is seated, and is formed integrally in such a way that the occupan" seat 52 as a whole extends diagonally upward to the rear from the front side, [0053] Also, as shown in Fig. 4, a front flange 74 is formed at the front end portion 24a of the storage box 24. A hinge portion 73 rhat rotatably supports the occupant seat 52 is miounted to the front flange 74. The hinge portion 73 includes a stationary portion 77, and a hinge bracket 79 that is rotatably mounted to the stationary portion 77 via a hinge shaft 78. The opening 24k of the storage box 24 is opened and closed by rotating the occupant seat 52 about the hinge shaft 78. Upon closing the occupant seat 52, the opening 24k of the storage box 24 is closed, thereby preventing intrusion of rainwater or dust into the storage box 24 from the outside. It should be noted that reference numerals 76, 76 each denote a fastening member. [0034] As shown in Figs. 7 and 8, the front-side portion of the storage box 24 is formed so as to allow storage of a helmet H. The top portion of the stored helmet H is received by a helmet cushion portion 90 provided at the bottom of the occupant seat 52, thereby regulating the storage position of the helmet H. [0035] Also, as shown in Fig. 5, in the bottom surfaces 24A, 24B, 24C and side wall pcrtion of the storage box 24, relief portions 200, 201, 100, where the side wall portion is recessed inward of the storage box 24 so as to avoid interference with the above- mentiorjcd parts, are formed as appropriate. The relief portion 200 is provided in the bottom surface 2^A, and nas an upwardly recessed shape so as to avoid interference with an upper portion of the throttle body 3 (see Fig. 2) . The relief portion 201 is provided in each of left and right corner portions formed by the bottom surface 2^.A, the bottom surface 24E, and the side wall portion, and has a shape that is recessed inward of the storage box 24 so as to avoid interference with the case of the air cleaner 2. Further, the relief portion 100 is provided at the left corner portion formed by the bottom surface 243^ the bottom surface 24C, and the side wall portion. As shown in Fig. 9, the relief portion 100 has a shape that is recessed inward of the storage box 24 so as to avoid interference with nuts 33 (see Fig. 9) that are fastened from the inner side of the vehicle body to upper portions of the rear cushion units 27L, 27R, which are mounted to the rear cushion bolts 28L, 28R, and to the rear cushion bolts 26L, 28R. In the following, the relief portion on the left side is denoted by lOOL, and the relief portion on the right side is denoted by lOOR. [0036] As shown in Figs. 5 to 7, the relief portions lOOL, lOOR respectively include inner wall surfaces lOlL, lOlR that are erected substantially vertically, upper flat surfaces 102L, 102R (flat surfaces; indicated by diagonally lines in Figs. 6 and 7) that extend to the outside of the vehicle body form the upper ends of the inner wall surfaces lOlL, iOlR, and front inclined surfaces 103L, 105? that are inclined diagonally downward to the front cf the vehicle body from the rear ends of the upoer flat surfaces 102L, 102R. [0037] The upper flat surfaces 102L, 102R are forined so as to be located at substantially equal heights (at heights that do not produce a vertical step) . Also, as shov.'n in Fig. 9, the inner wall surfaces lOlL, lOlR, the upper flat surfaces 102L, 102R, and the front inclined surfaces 103L, 103R are provided at positions that make it possible to avoid interference with the rear cushion units 27L, 27R and in such a way that the recess of the relief portions lOOL, lOOR become as small as possible, thereby maximizing the storage volume of the storage box 24. Also, the opening 24k of the storage box 24 is located above the upper flat surfaces 102L, 102R. [003S] The space located above the upper flat surfaces 102L, 102B and extending up to the opening 24k is referred to as a first storage space SI, In the first storage space SI, a piece of luggage having a flat surface on the outer side of a rectangular storage item 203 of about A5 size (for example, an attache case; see Fig. 8) can be placed. By placing the flat surface of this attache case on both the upper flat surfaces 102L, 102R (or on one of the upper flat surfaces 102L, 102R), the above-mentioned attache case or the like can be stored in a stable position without being tilted obliquely. [0G39] Also, an inclined bottom surface 104 (inclined surface) that is inclined diagonally downward to the front from the rear side of the vehicle is formed between the inner vjall surfaces lOlL, lOlR (^between the relief portions iOOL, lOOR) that are opposed to each other so £S to face toward the inner side of the vehicle body. The inclined bottomi surface 104 is inclined toward a bottom surface 24b located in the front side of the storage box 24. Also, the angle of inclination of the inclined bottom surface 104 is so determined as to avoid interference with the movable range of the rear wheel 41 located below the inclined bottom surface 104 (the range in which the rear wheel 41 can be moved vertically by the rear cushion units 27L, 27R). [0040] The space located above the inclined bottom surface 104 is referred to as a second storage space. A long piece of luggage 204 (for example, a folding umbrella; see Fig. S) can be placed in this second storage space S2. By placing this piece of luggage along the inclination of the inclined bottom surface 104, or by placing this piece of luggage along this inclination all the way to the bottom surface 24b on the front side, a long piece of luggage can be stored in the storage space of the storage box 24. [0041] In the storace box structure for a motorcycle according to the embodiment of the present invention, relief portions IOOL, lOOR for avoiding interference with upper portions of the rear cushion units 27L, 2'7R are provided on both sides of the storage box 24, and the first storage space SI is formed by forming the upper flat surfaces 102L, 102R in upper surfaces of the relief portions lOOL, lOOR. Thus, the rectangular storage item 203 cf about A5 size (for example, an attache case or a small laptop (notebook) personal computer) can be stored in the firsr storage space SI in a horizcntally laid state. That is, it is possible tc make effective use ci the storace space of the storage box 24 bv optimizing the shape of the relief portions lOOL, IGOR. Also, the second storage space S2 is formed by forming the inclined bottom surface 104 between the left and right relief portions lOOL, lOOR. Thus, the long piece of luggage 204 (for example, a folding umbrella) can be stored along the inclined bottom surface 104. That is, a decrease in the storage space of the storage box 24 can be minimized by optimizing the shape of the portion between the relief portions IDOL, IGOR. [0042] Also, the upper portions of the rear cushion units 27L, 27R are mounted to the rear side of the rear frames 21L, 21R, and the relief portions lOCL, lOOP, are provided in the rear side of the storage box 24. Thus, no constraint is imposed on the space in the front side and az the central portion of the storage box 24 by the relief portions lOOL, lOOR. Therefore, it is possible to make effective use of the storage space of the storage box 24, and convenience is not impaired. [0043] Further, the inclined bottom surface 104 is inclined toward the bottom surface 24b in the front side of the storage box 24, so a long piece of luggage can be stored along the inclined bottom surface 104 from the bottom surface 24b of the storage box 24. Therefore, effective use of the storage space can be made, ^hus eliiTiinating the inconvenience of net being able to fit a Icng piece cf luggage in rhe s-orage space even when the relief portions lOOL, lOOR ere foriried. Also, the uppier flat surfaces 102L, 102R are icrmed at ihe same height, so the flat side of an attache case or the like can be placed in intimace contact with the upper flat surfaces 102L, 102R. Therefore, the attach^ case or the like can be stored in a stable position, thereby enhancing the convenience of storage. {0045] While an embodiment of the present invention has been described above, various modifications and changes are possible on the basis of the technical scope of the present invention. For example, while in this embodiment the rear cushion units 27L, 27R are provided on both side portions of the vehicle, the rear cushion units 27L, 27R may be provided on only one side. In this case as well, by forming the relief portions lOOL, lOCR on both sides, the storage box 24 used can only be of a single kind (or a common part) irrespective of the number of the rear cushion units 27L, 27R installed, and also an attache case or the like can be stored in a stable manner on the left and right upper flat surfaces 102L, 102R.
