Since it is fastened to the back surface of the protruding portion 49b, the cable switch 92 can be used to change the direction in which the brake switch cable 87 extends in the vehicle front-rear direction to the vehicle width direction, and the bolt 90 that fastens the clip support member 91 Since it is oriented in the vehicle width direction, the processing applied to the step holder 49 to attach the clip support member 91 is facilitated.
  • the vertically extending portion 49 c of the step holder 49 extends downward from the support portion 49 a so as to extend below the swing arm 27 in a side view, and a side surface of a part of the exhaust device 40 of the internal combustion engine E.
  • At least a part of the pedal shaft 55 is arranged at a position overlapping in view, and is supported rotatably on the vertical extension portion 49c via the pedal shaft 55 below the swing arm 27 in side view.
  • the brake pedal 54 is formed to have a vertical arm portion 54d extending vertically so as to be disposed between the swing arm 27 and the step holder 49 in the vehicle width direction. Even if the exhaust device 40 is provided, the brake pedal 54 can be supported by the step holder 49 with a sufficient supporting force.
  • a brake is applied to the second master cylinder 63 attached to the step holder 49 and the drum brake B2 provided to the rear wheel WR so as to be able to generate a hydraulic pressure for operating the disc brake B1 provided on the front wheel WF. Since the brake operation force input from the brake pedal 54 is distributed to the rod 66 that mechanically transmits the operation force by the equalizer 65, the disc brake B1 of the front wheel WF and the rear wheel are operated by the operation of the brake pedal 54.
  • An interlocking brake can be configured in which the brake is operated in conjunction with the WR drum brake B2.
  • An intermediate portion of the equalizer 65 having one end connected to the second master cylinder 63 and the other end connected to the rod 66 is connected to the vertical arm 54d on the back side of the vertical arm 54d. Therefore, the rod 66 can be disposed as close as possible to the swing arm 27 side, and the rod 66 can be disposed closer to the drum brake B2 of the rear wheel WR in the vehicle width direction.
  • the step holder 49 has integrally and extends rearward in the vehicle front-rear direction, along the longitudinal direction of the front / rear extension part 49b. Since the delay spring 73 that extends and is disposed on the back side of the front-rear extension portion 49b is interposed, the length of the delay spring 73 can be ensured and the necessary spring force can be ensured while enhancing the design.
  • the stopper 57 for restricting the rotation end of the return side of the brake pedal 54 is attached to the lower portion of the step holder 49, the entire step holder 49 including the stopper 57 can be unitized and assembled. Can be increased.
