The signal/power cable outputs a fuel measurement signal to the control unit 40 through the harness 51 and themainharness 50. In addition, the signal/power cable supplies electric power supplied from a relay 45 to the fuel pump 27 through the harness 51 and the main harness 50. As shown in Fig. 4 which is a sectional view taken along line B-B in Fig. 2, a fuel supply pipe 15 is attached to the fuel delivery section 27a of the fuel pump 27. The fuel supply pipe 15 passes through the bottom surface section 21 of the fuel tank 20 using the space B, extends upward on the left side in the front outside the fuel tank 2 0 from the bottom surface section 21, and forms a bent section 15a near the swing center C of the fuel tank 20 to be connected to the injector 12. In addition, as shown in Fig. 5, in the fuel supply pipe 15, a bent section 15b is also formed on a side where the fuel supply pipe 15 passes through the bottom surface section 21 of the fuel tank 20 from the fuel delivery section 27a. In the fuel supply pipe 15, a part connected to the fuel delivery section 27a and a part connected to the injector 12 are formed of a metal member. Intermediate parts forming the bent sections 15a and 15b are formed of a flexible member such as rubber. The bent section 15a of the fuel supply pipe 15 is provided to be located closer to a swing center in the front side of the fuel tank 20 than the injector 12 and the fuel delivery section 27a when viewed from the side of the vehicle. The fuel supply pipe 15 has a length not interfering with the fuel tank 20 at the time when the fuel tank 2 0 is turned and opened. The fuel supply pipe 15 between the bent sections 15a and 15b and the fuel delivery section 27a is provided along a lower surface of the flat section 21b of the fuel tank 20 using the space B formed between the flat section 21b of the fuel tank 20 and the upper surface of the sub-frame 6. The bent section 15a of the fuel supply pipe 15 is provided to be located above the main frame 4, the injector 12, and the fuel delivery section 27a when viewed from the side of the vehicle. In the space A formed between the bottom surface front center section 21a of the bottom surface section 21 of the fuel tank 20 and the upper surface of the main frame 6, the control unit 40 for controlling steering of the motorcycle 1 is fixed to the upper surface of the main frame 6 by an attaching member 41. A harness 52 is connected between the control unit 40 and the injector 12, the throttle body 16, the intake air pressure sensor 17, the liquid level meter 28, and the like via the main harness 50. The control unit 40 controls operations of various actuators related to the engine unit 7 on the basis of various detection signals from various sensors. In the space A, a relay 45 for controlling power supply to a control system of the motorcycle 1 is fixed to the upper surface of the main frame 4 by an attaching member 46. A harness 53 is connected to the relay 45 and is connected to the main harness 50. The relay 45 supplies electric power to the injector 12, the throttle body 16, the intake air pressure sensor 17, the liquid level meter 28, the control unit 40, and the like through the harness 53 and the main harness 50. The main harness 50 is disposed along sides of the main frame 4 and the sub-frame 6 and the like. Fig. 5 shows a state in which the fuel tank 20 is turned and opened to the front of the vehicle with respect to the swing center C. As shown in the figure, in performing an operation for turning and opening the fuel tank 20, after the respective harnesses 51, 52, and 53 of the power supply section 27c, the control unit 40, and the relay 45 are removed, the flat section 21b of the fuel tank 20 rises in a direction to the front of the vehicle, the bent section 15a of the fuel supply pipe 15 extends according to this rising operation, and the fuel supply pipe 15 between the fuel delivery section 27a and the bent section 15a opens mainly upward. In this way, when the fuel tank 20 is turned and opened, since the bent section 15a of the fuel supply pipe 15 extends and the fuel supply pipe 15 between the fuel delivery section 27a and the bent section 15a opens mainly upward, the fuel supply pipe 15 never interferes with the other members and never hinders maintenance. As described above, in the motorcycle 1 in this embodiment, the bent section 15a of the fuel supply pipe 15 is provided to be located closer to the swing center in the front of the fuel tank 20 than the injector 12 and the fuel delivery section 27a when viewed from the side of the vehicle. The fuel supply pipe 15 has a length not interfering with the fuel tank 20 when the fuel tank 2 0 is turned and opened. In addition, the fuel supply pipe 15 between the bent section 15a and the fuel delivery section 27a is provided along the lower surface of the flat section 21b of the fuel tank 20 using the space B formed between the flat section 21b of the fuel tank 20 and the upper surface of the sub-frame 6. The bent section 15a is provided to be located above the main frame 4, the injector 12, and the fuel delivery section 27a when viewed from the side of the vehicle. Therefore, it is possible to arrange the fuel supply pipe in a compact manner while securing a necessary length thereof and improve maintainability. When the fuel tank is turned and opened, the fuel supply pipe between the bend section and the fuel delivery section moves mainly upward. Thus, it is possible to control interference between the fuel supply pipe and the other components and improve maintainability. In addition, when the fuel tank is turned and opened, the fuel supply pipe between the bent section and the fuel delivery section mainly moves and the part of the fuel supply pipe extends along the lower surface of the fuel tank. Thus, it is possible to control interference between the fuel supply pipe and the other components and improve maintainability. Note that, in the embodiment described above, the fuel supply pipe 15 has the two bent sections 15a and 15b. However, the invention is not limited to this. For example, as shown in Fig. 6, a fuel supply pipe 50 having plural bent sections may be used. Fig. 6 shows the fuel pump 27 and the fuel supply pipe 50 viewed from the bottom surface side of the vehicle. In this case, the injector 12 is arranged on the right side with respect to a vehicle center D in the figure and the fuel delivery section 27a is arranged downward to the left with respect to the vehicle center D in the figure. Note that the front of the vehicle is set in the upper part in the figure and the rear of the vehicle is set in the lower part in the figure. In this case, in the fuel supply pipe 50, a first bend section 50a, a second bent section 50b, and a third bent section 50c are formed in order from a part close to the fuel delivery section 27a. Intermediate parts having these first to the third bent sections 50a to 50c are formed of a flexible member such as rubber. Note that the second bent section 50b is provided to be located above the main frame 4 when viewed from the side of the vehicle. In this fuel supply pipe 50, the respective intermediate parts including the first bent section 50a and the third bent section 50c are provided along the lower surface of the flat section 21b of the fuel tank 20 using the space A between the bottom surface front center section 21a of the fuel tank 20 and the upper surface of the main frame 4 and the space B formed between the flat section 21b and the upper surface of the sub-frame 6. When the fuel tank 20 is turned and opened, the fuel supply pipe 50 opens mainly upward in the part between the fuel delivery section 27a and the secondbent section 50b. Thus, it is possible to obtain the same advantages as the embodiment described above. Note that, in the examples of the fuel supply pipes 15 and 50, the intermediate parts having the bent sections are formed of a flexible member. However, the invention is not limited to this. For example, it is also possible that the parts having the bent sections are formed of a flexible member and the bent sections are connected by metal pipes or the like. In short, a structure of a fuel supply pipe is not specifically limited as long as parts having bent sections are formed of a flexible member. In addition, in the examples of the fuel supply pipes 15 and 50, the fuel supply pipes 15 and 50 have one bent section and three bent sections, respectively. However, the invention is not limited to this. A fuel supply pipe may have two or four or more bent sections. The number of bent sections is not specifically limited. In addition, respective bent sections of a fuel pipe may be formed of metal pipes having a universal joint function.

According to the invention, the bent section of the fuel pipe is provided to be located closer to the swing center of the fuel tank than the fuel supply device and the fuel delivery section when viewed from the side of the vehicle. Thus, it is possible to arrange a fuel pipe in a compact manner while securing a necessary length of the fuel pipe to improve maintainability. The vehicle of the invention adopts a constitution in which the bent section is provided to be located above the fuel supply device and the fuel delivery section when viewed from the side of the vehicle. According to this constitution, since the bent section is provided to be located above the fuel supply device and the fuel delivery section when viewed from the side of the vehicle, when the fuel tank is turned and opened, the part between the bent section and the fuel delivery section mainly moves.
