Claims

[Scope of utility model registration request]

(1) A parking brake pedal rotatably supported by a pedal bracket from an original position to a depressed position and operatively connected to the parking brake in order to apply the parking brake in the depressed position; an engaging tooth provided along an arc centered on the center line of motion, and is attached to the pedal bracket so as to be able to engage and detach from the engaging tooth, and engages with the engaging tooth to cause the pedal to move. a pawl that prevents the pawl from returning from the depressed position to the original position; and a pawl that can be biased selectively in a forward direction in which the pawl engages with the engaging tooth and in a reverse direction in which it disengages from the engaging tooth; a biasing device configured to have a magnitude such that the biasing force in the opposite direction does not cause the pawl to disengage against the meshing force with the engagement teeth; and a biasing device configured to be able to cooperate with the biasing device; a manual operation device that reverses the biasing force direction of the biasing device from a forward direction to a reverse direction by manual operation; 1. A parking brake operating device, characterized in that the prevention of return of the pedal is released.

(2) The urging device and the pedal are arranged so that the direction of the urging force of the urging device is automatically reversed from the opposite direction to the forward direction during the process of returning the pedal from the depressed position to the original position. The parking brake operating device according to claim 1, wherein the parking brake operating device is interlocked with each other.
