6 is a view of the rear part of the vehicle body as seen from the right side, and FIG. 7 is a view as seen from above.
As shown in FIGS. 6 and 7, the pipe 103 made of a flexible rubber hose connected to the rear wheel brake device 102 includes the rear wheel brake device 102 of the pair of left and right swing arms 35. It is routed on the upper surface 35T of the swing arm 35 on the side (right side).
The brake caliper 125 of the rear wheel brake device 102 to which the pipe 103 is connected is disposed above the right swing arm 35 and in front of the rear wheel shaft 26A, and the joint part 125A to which the pipe 103 is connected includes a brake The caliper 120 is arranged so as to protrude forward and upward.

One end (rear end) 35R of the pipe 103 is connected to the joint part 125A by a pipe connecting member 126, and is inclined forward and downward from the joint part 125A to form a front lowering pipe part 103A that functions as a movable pipe part. Thus, after extending toward the swing arm upper surface 35T, the clamp arm 161 provided at the front and rear intermediate position of the swing arm upper surface 35T, and the locking portion 164 provided on the front side of the swing arm upper surface 35T, the swing arm 35 is supported by the swing arm upper surface 35T so as to form a straight pipe portion 103B extending in the front-rear direction along the direction 35.
Here, one end 35R of the pipe 103 is connected to be rotatable about an axis LF (see FIG. 6) of the pipe connecting member 125B, and the front lowering pipe portion 103A on the one end 35R side is connected to the pipe 103 itself. It is a flexible and movable movable piping section. For this reason, when the brake caliper 125 is one-push type and the joint portion 125A moves outward in the vehicle width due to brake operation or the like, or because the chain adjustment (adjusts the front and rear position of the rear wheel shaft 26A with respect to the swing arm 35), When 125A is relatively moved, the direction of the one end 35R side of the pipe 103 can be made to follow.

  However, if the one end 35 </ b> R of the pipe 103 is freely rotated outward in the vehicle width direction, there is a possibility that the front-falling pipe portion 103 </ b> A of the pipe 103 may protrude greatly outward in the vehicle width direction. For this reason, in this configuration, a detent member 125C (see FIG. 6) is provided on the brake caliper 125 side to regulate the rotation limit of the pipe 103 to the outside in the vehicle width direction.

A length extending from the vicinity of the rim 26R to the front surface of the rear wheel 26 on the ground contact surface (also referred to as a tread surface) 26S is formed. Thus, if the nylon protector 163 extends from the vicinity of the wheel rim 26R of the rear wheel 26 to the front of the ground contact surface 26S, scattered matter (water, mud, etc.) from the rear wheel 26 side adheres to the pipe 103. This can be avoided efficiently.

The locking portion 164 is a locking component that is fixed to the base end side (shaft support side) of the swing arm upper surface 35T by welding or the like, and holds the pipe 103 and the nylon protector 163 that covers the pipe 103 in a detachable manner.
The locking portion 164 is formed by bending a metal wire member, and extends outward in the vehicle width direction with respect to the base end side fixed to the swing arm 35. The locking portion 164 has an outer end in the vehicle width direction. The part has an opening part 164B (see FIG. 7) that opens apart from the swing arm upper surface 35T by a predetermined distance smaller than the diameter of the pipe 103.
In addition, on the inner side in the vehicle width direction from the opening portion 164B, there is a hook portion 164A that curves upward in a convex arc shape, and by passing the pipe 103 and the nylon protector 163 through this hook portion 164A, Locked.
