Claims

[Scope of utility model registration request]

A bracket fixed to the vehicle body, a brake pedal that is rotatably supported by the bracket and rotates from a return position to a depressed position to operate the parking brake, and a brake pedal that returns from the depressed position to the return position. a return preventing means for preventing the return preventing means; and a brake release means for releasing the blocking action of the return preventing means to release the parking brake;
A foot-operated parking brake actuating device comprising: a deceleration means that performs a deceleration effect when the brake pedal rotates from a depressed position to a return position, wherein the deceleration means is provided with one of the bracket and the brake pedal. A rotary body formed of an elastic material is attached to the rotor so as to be rotatable about an axis parallel to the rotating axis of the brake pedal, and the other of the two is brought into contact with the circumferential portion of the rotary body so that the brake pedal returns to the return position. A foot-operated parking brake actuating device characterized in that a cam is provided which rotates a rotating body and compresses it in the radial direction as it rotates, and the cross-sectional shape of contact between the rotating body and the cam is wedge-shaped.
