Claims

[Claims for Utility Model Registration] (1) A brake pedal that is rotatably supported by a bracket and has sector teeth, and that operates a parking brake when depressed, and a pawl that engages with the sector teeth. a first pawl rotatably supported by the bracket and biased by a first elastic member in a direction in which the pawl portion thereof engages with the sector tooth; and a pawl portion that engages with the sector tooth; It is rotatably supported by the bracket, and its claw portion is biased by a second elastic member in a direction to engage with the sector tooth, and the length of the claw straight portion that contacts the sector tooth of the claw portion is equal to a second pole that is shorter than the length of the straight claw portion of the first pole and has a radius of curvature of the tip of the claw larger than the radius of curvature of the tip of the claw of the first pole; and a second pole that is engageable with the first pole. a release lever provided with a release portion and rotatably supported by the bracket, the release portion rotating the first pawl in a direction in which a claw portion of the first pawl is removed from the sector tooth; and a release lever provided on the second pawl; an engaged portion provided on the first pole and engaged with the engaged portion of the second pawl to rotate the second pawl together with the first pawl in a direction in which the claw portion of the second pawl is disengaged from the sector tooth; and an engaging portion to be moved, and the positional relationship between the engaging portion of the first pawl and the engaged portion of the second pawl is such that the claw portion of the first pawl is disengaged from the sector tooth. A foot-operated parking brake pedal device, characterized in that the claw portion of the second pawl is determined to be detached from the sector tooth. (2) The first pawl and the second pawl are rotatable around the same axis, and their claws engage any and the same tooth surface of the sector tooth in the tooth width direction. A foot-operated parking brake pedal device according to claim 1.
