Claims

[Claims for Utility Model Registration] A pedal, a bracket rotatably supporting the pedal, and an arc formed on either the pedal or the bracket along an arc centered on the center of rotation of the pedal. a pawl rotatably mounted on the other hand and meshing with the ratchet tooth at a pointed end; a pedal pad rotatably mounted on the free end of the pedal; and a pedal pad rotatably mounted on the free end of the pedal; an arm extended to the end; a rod having a longitudinal shape and having a first end engaged with the pole and a second end engaged with the arm; the rod being extended to the second end; a first spring member biasing the pawl in a direction toward the first end from the ratchet tooth;
a second spring member biasing the pawl with a force smaller than the meshing force between the pawl and the ratchet teeth, and the pawl and the arm portion are applied to the rod from the second end to the second spring member. A foot-operated parking brake device characterized in that the foot-operated parking brake device is engaged so as to be relatively movable in a direction toward one end, but substantially immovable in the opposite direction.
