As a result, the reserve tank 58 can be protected.
Further, since the removed reserve tank 58 can be temporarily fixed using the pillion step (step 32R) and the brake oil can be replaced, the maintainability can be improved.

  A part of the reserve tank 58 is disposed so as to be exposed from the right rear side cover 78R. Even in a vehicle in which the side portion (outer surface 94) of the reserve tank is covered with the side covers 78L and 78R, the amount of oil in the reserve tank 58 can be confirmed. As a result, good maintainability is ensured.

  The reserve tank 58 is disposed inward of the vehicle width of the pillion step brackets 31L and 31R, and is disposed in front of the cushion unit (rear cushion unit 39R). That is, the reserve tank 58 is guarded by the pillion step bracket 31R extending outward in the vehicle width direction, and the rear of the vehicle is guarded by the rear cushion unit 39R. As a result, the protective effect of the reserve tank 58 can be further enhanced.

  Further, the lower end 100 b of the rib wall is extended so as to overlap the rear wheel 14. Mud or the like that the rear wheel 14 splashes during traveling is guarded by the rib wall 100. As a result, the reserve tank 58 can be effectively protected from the mud splashed by the rear wheel 14.

  Returning to FIG. 5, the vehicle front surface 91, the rear surface 93, and the vehicle width direction inner surface 92 of the reserve tank 58 are surrounded by the rib wall 100. The reserve tank 58 can be protected from the direction. Further, since the outer surface 94 of the reserve tank 58 in the vehicle width direction is open, it is possible to easily check the amount of oil from the side of the vehicle, and to improve the maintainability of the rear wheel braking device 50. .

  Although the present invention is applied to a motorcycle in the embodiment, it can also be applied to a saddle-ride type tricycle and can be applied to a general saddle-ride type vehicle.

  The present invention is suitable for motorcycles.
