In addition, the rear wheel brake cable 150 is connected to the lower connecting shaft 83 via the end metal fittings 151 .

In the operation force distribution mechanism 60 , when the brake pedal 26 is depressed, the brake pedal 26 swings counterclockwise around the pedal swing shaft 42 . In this way, the balancer rocking shaft 82 moves to the rear side of the vehicle body accordingly. At this time, since the balancer 80 is urged clockwise by the elastic force of the delay spring 301 and pressed against the stopper member 90, only the lower side connecting shaft 83 moves to the rear of the vehicle body, and starts pulling the rear wheel brake wire cable 150.

Then, when the brake pedal 26 is further stepped on and the rear wheel brake BR starts to generate a braking force, the rear wheel brake cable 150 is less likely to be pulled further. Therefore, the balancer 80 moves clockwise around the balancer swing shaft 82 . Start swinging in the direction. At the beginning of the start of the swinging operation, the upper connecting shaft 81 moves to the rear of the vehicle body to start pulling the interlocking cable 100 . That is, when the brake pedal 26 is lightly stepped on, the rear wheel brake BR is preferentially activated, and when the rear wheel brake BR is depressed further from the position where the braking force is generated, the front wheel brake BF is activated. Thereby, a natural braking feeling can be obtained.

In the present embodiment, since the balancer 80 is disposed below the vehicle body rather than the pedal rocking shaft 42 of the brake pedal 26 , the balancer 80 is located above the vehicle body rather than the pedal rocking shaft 42 of the brake pedal 26 . Compared with the structure in which the balancer 80 is arranged, the interval between the back surface of the low floor floor 25 and the pedal rocking shaft 42 of the brake pedal 26 can be shortened. Thereby, the floor surface of the low floor floor 25 can be suppressed low, and the size of the brake pedal 26 can be reduced.
