<Effect>
As described above, the motorcycle 1 of the above embodiment includes a vehicle body frame 20 including a head pipe 21 provided in the vehicle, a main frame 22 extending from the head pipe 21 toward the rear of the vehicle, and the center of the head pipe 21. A steering system 40 supported by the head pipe 21 so as to be steerable about the axis HL, an electrical component 50 attached to the steering system 40 and moving as the steering system 40 is steered, and a wiring 60 extending from the electrical component 50. , the wiring 60 is fixed at a first fixing point P1 of the electrical component 50, the wiring 60 extends to the left in the vehicle width direction from the first fixing point P1, and then bends to extend to the right. , is fixed at a second fixing point P2 of the body frame 20, and the central axis HL of the head pipe 21 is positioned downward toward the front side of the vehicle when viewed from the side of the vehicle. A straight line KL passing through the first fixed point P1 and the second fixed point P2 is inclined to be positioned higher toward the front side of the vehicle when viewed from the side of the vehicle. When viewed from the side, they intersect each other substantially perpendicularly.
According to this configuration, the straight line KL passing through the first fixed point P1 and the second fixed point P2 and the center axis HL of the head pipe 21 intersect substantially perpendicularly when viewed from the side of the vehicle, so that the steering system 40 is steered. Sometimes the wiring 60 can be moved on the plane containing the straight line KL. In addition, since the wiring 60 extends to the left in the vehicle width direction from the first fixed point P1 and then curves and extends to the right, the wiring 60 extends in the vehicle width direction and the vehicle front and back when the steering system 40 is turned. Can move in only two directions. Therefore, compared to the case where the wiring 60 moves in the three directions of the vehicle up-down direction, the vehicle width direction, and the vehicle front-rear direction, the movement range of the wiring 60 becomes smaller, and the space is ensured so that the wiring 60 does not come into contact with the vehicle parts. can be made smaller. Therefore, the degree of freedom in layout of vehicle parts can be increased. In addition, the appearance can be improved as the degree of freedom in the layout of vehicle parts increases. In addition, since the wiring length is shortened by the amount that the moving range of the wiring 60 is reduced, cost reduction can be achieved.

In the above embodiment, when the steering system 40 is not being steered, the first fixing point P1 and the second fixing point P2 are positioned in the vehicle width direction with respect to the central axis HL of the head pipe 21 as viewed from the front of the vehicle. By arranging them on the same side, the following effects are obtained.
Since the two fixing points P1 and P2 of the wiring 60 that move when the steering system 40 is turned are on the same side in the vehicle width direction with respect to the center axis HL of the head pipe 21, the steering system 40 is not steered. In this state, the wiring length can be shortened compared to the case where the two fixing points P1 and P2 are on opposite sides of the center axis HL of the head pipe 21 in the vehicle width direction.

In the above embodiment, when the steering system 40 is fully steered at least toward the vehicle width direction side where the first fixing point P1 and the second fixing point P2 are arranged, the first fixing point P1 and the second fixing point P2 Since the distance in the longitudinal direction of the vehicle is shorter than the distance when the steering system 40 is not steered, the following effects are obtained.
In a state in which the steering system 40 is fully steered to the vehicle width direction side where the two fixed points P1 and P2 are located, the distance between the two fixed points P1 and P2 in the longitudinal direction of the vehicle is greater than the distance before the steering system 40 is turned. The wiring length can be shortened as compared with the case where the wiring length is also long.

In the above embodiment, when the steering system 40 is fully steered at least toward the vehicle width direction side where the first fixing point P1 and the second fixing point P2 are not arranged, the first fixing point P1 and the second fixing point P2 are arranged on opposite sides in the vehicle width direction with respect to the center axis HL of the head pipe 21 in a front view of the vehicle.
When the steering system 40 is fully steered in the vehicle width direction where there are no two fixing points P1 and P2, the two fixing points P1 and P2 are on the same side in the vehicle width direction with respect to the central axis HL of the head pipe 21. The wiring length can be shortened compared to the case of .

In the above embodiment, when the steering system 40 is not being steered, the routing portion of the first fixing point P1 and the routing portion of the second fixing point P2 of the wiring 60 are parallel to each other when viewed from the top of the vehicle. By being arranged, the following effects are produced.
When the steering system 40 is not steered, compared to the case where the wiring portions of the two fixed points P1 and P2 in the wiring 60 are arranged so that the center lines of the wiring 60 intersect with each other when viewed from the top of the vehicle, the steering system Since the force applied in the compressing direction to the wiring 60 that moves when the steering wheel 40 is steered, deformation of the wiring 60 can be suppressed.

In the above-described embodiment, when the steering system 40 is not being steered, the routing portion of the first fixing point P1 and the routing portion of the second fixing point P2 of the wiring 60 are positioned at the vehicle width from each other when viewed from the top of the vehicle. By arranging them along the direction, the following effects can be obtained.
Since the force applied in the compressing direction to the moving wire 60 when the steering system 40 is steered is reduced, deformation of the wire 60 can be more effectively suppressed.

In the above embodiment, the electrical component 50 is provided with the extending portion 53 having the opening 53a through which the wiring 60 passes, and the wiring 60 extends from the opening 53a of the extending portion 53 to one side and then bends. The portion of the wiring 60 that is folded back to the opposite side and is fixed at the first fixing point P1 together with the extending portion 53 provides the following effects.
If the wiring 60 is folded back to the opposite side at the opening 53a of the extending portion 53, the wiring 60 moves around the opening 53a when the steering system 40 is steered, thereby increasing the durability of the wiring 60. In order to prevent deterioration, it was necessary to improve the strength of the terminal. On the other hand, according to this configuration, the wiring 60 does not move about the opening 53a when the steering system 40 is turned. Therefore, the durability of the wiring 60 can be improved without increasing the strength of the terminal. can be done.

In the above-described embodiment, the first fixing point P1 and the second fixing point P2 are arranged in front of the head pipe 21 when viewed from the side of the vehicle, thereby providing the following effects.

In the above-described embodiment, the fixing member 62 having the second fixing point P2 is provided on the third stay 73 joined to the second stay 72, thereby providing the following effects.
Since the portions of the wiring 60 that move with the steering of the steering system 40 can be collectively arranged around the head pipe 21, the degree of freedom in the layout of the vehicle parts can be increased. In addition, as the degree of freedom in layout of vehicle parts increases, appearance can be improved. In addition, the range of movement of the wiring 60 is reduced in the longitudinal direction of the vehicle, and the length of the wiring is shortened accordingly, so that cost reduction can be achieved.
