Claims

[Claims for Utility Model Registration] A pedal bracket, a pedal body rotatably supported around a single axis by the pedal bracket and to which a parking brake cable is connected to a first arm, and a second arm of the pedal body. a pedal pad rotatably mounted around an axis parallel to the rotation center line of the pedal bracket; and a tangent to the rotation locus of the end at an end of the pedal pad on the side closer to the pedal bracket. a bushing rod mounted movably in a direction substantially parallel to the pedal bracket, ratchet teeth provided on the pedal bracket along an arc centered on the rotation center line of the pedal body, and a pawl that meshes with the ratchet teeth. and an arm extending to a position where it can contact the tip of the bushing rod,
a pawl attached to the pedal body so as to be rotatable about an axis parallel to a rotation center line of the pedal body; and a pawl so that the pawl is rotated in a direction in which the pawl portion engages with the ratchet teeth. a first spring member that biases the bushing rod; a second spring member that biases the bushing rod toward the arm portion of the pole; and a stopper that defines a limit of advancement of the bushing rod due to the biasing force of the second spring member. and when the pedal pad is in the original position, the pawl is urged by the first spring member in a direction to mesh with the ratchet teeth, and when the pedal pad is rotated from the original position to the operating position. The second spring member is configured to bias the pawl away from the ratchet teeth via the bushing rod with a force that overcomes the biasing force of the first spring member.
