Claims

[Claims 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 pawl mounted so as to be rotatable in a direction parallel to the pedal and meshing with the ratchet teeth at a tip end thereof; a pedal pad mounted to a distal end portion of the pedal so as to be rotatable in a direction parallel to the rotational direction of the pedal; , an intermediate portion is pivotally connected to the intermediate portion of the pedal, and engages the pedal pad at a first end, and rotates in a direction opposite to the pad when the pad is rotated from the original position to the active position. a second lever that is rotatably attached to the bracket so as to be rotatable in a direction parallel to the direction of rotation of the pedal, and engaged with the pawl so as to rotate the pawl in a direction in which it meshes with the ratchet teeth; On the other hand, it engages with the second end of the second lever near the center line of rotation of the pedal, and as the second lever rotates, it is rotated in a direction opposite to the first lever and engaged with the pole. a second lever to be disengaged; a first spring member for engaging the second lever with the pawl and biasing it into engagement with the ratchet teeth; and an orientation for disengaging the pawl from the ratchet teeth. A foot-operated parking brake operating device comprising: a second spring member biasing with a force smaller than the engagement force between the pawl and the ratchet teeth.
