Claims (1)

[Claims for Utility Model Registration] A bracket that is fixed to the vehicle body, and a ratchet that is rotatably disposed on the bracket so as to be rotatable about a first axis, and that has a ratchet that rotates along an arc shape centered on the first axis. a brake pedal formed with a brake pedal;
a pawl disposed on the bracket so as to be rotatable about a second axis parallel to the axis and engaged with the ratchet; the brake cable is tightened and parked when the brake pedal is operated by foot from its original position. When the brake is activated, the engagement between the ratchet and the pawl prevents the brake pedal from rotating toward its original position, thereby maintaining the parking brake in its activated state, while the release operation member is activated. In a foot-operated parking brake operating device of a type that, when operated, releases the engagement between the ratchet and the pawl and allows rotation of the brake pedal in a direction toward its original position, The brake pedal is disposed on the bracket so as to be rotatable around three axes, and is engaged with the brake pedal by operating the release operation member to rotate the brake pedal in a direction opposite to the original position, and also performs the release operation. a release pole that allows the brake pedal to rotate toward its original position when the operation of the member is released; and a release pole disposed on the bracket so as to be rotatable about a fourth axis parallel to the first axis. a rotating member that is rotated in one direction by the operation of the release operation member; a return spring that biases in a direction opposite to the one direction; and a return spring that is disposed astride the pawl and the rotating member, allowing relative movement with respect to at least one of the members, and the biasing force of the return spring a connecting rod that is positioned at a relative movement end when the rotating member is rotated in a direction opposite to the one direction, and biases the pawl in a direction to engage the pawl with the ratchet; When the release operation member is operated in the engaged state and the rotating member is rotated in the one direction to separate the connecting rod from the relative movement end, the pawl is brought into engagement with the ratchet. The lever is biased directly or indirectly in a direction in which the lever is released, and the brake pedal is rotated by the release pawl in a direction opposite to the original position, thereby releasing the engagement between the pawl and the ratchet. 1. A foot-operated parking brake operating device, characterized in that it has a biasing means.
