Claims

[Scope of Claim for Utility Model Registration] A pedal rotatably attached to a bracket and having ratchet teeth formed along an arc centered on the center line of the rotation; A pedal pad is rotatably mounted in a direction parallel to the direction of power, and an intermediate part is pivotally connected to the intermediate part of the pedal, and one end engages with the pedal pad, so that the pedal pad acts from its original position. a lever that is rotated in a direction opposite to the pedal pad when the pedal is rotated to the position; a second lever that engages with the other end of the second lever near the center line and is rotated in the opposite direction to the second lever as the first lever rotates; a pawl that is rotatably mounted in a direction parallel to the pedal pad and that engages with the ratchet teeth at its pointed end; when the pedal pad is in the original position, the pawl is urged in a direction that engages with the ratchet teeth; When the pedal pad is rotated to the operating position and the first and second levers are rotated, the direction of the biasing force of the pawl is changed to cause the pawl to move toward the ratchet in conjunction with the rotation of the second lever. 1. A foot-operated parking brake operating device comprising: spring means for biasing the pawl in a direction away from the teeth and biasing the pawl with a force smaller than the frictional force between the pawl and the ratchet teeth.
