Claims

[Scope of utility model registration request]

A plunger with a handle attached to one end is attached to the vehicle body so that it can slide in the axial direction and rotate around the axis, and a parking brake operation cable is connected to the other end of the plunger, so that the driver can put his hand on the handle. When the driver pulls the plunger, the parking brake is activated, and when the driver pulls the plunger, the brake reaction force prevents the plunger from returning, and this blocking action is achieved by rotating the plunger. In a parking brake operating device provided with a locking mechanism for releasing, the tip of a shaft provided integrally with the handle cannot be moved in the axial direction relative to a sleeve provided coaxially and integrally rotatably with one end of the plunger. and rotatable around an axis, and the tip of the shaft of the handle accommodated in the sleeve has a generally elliptical cross section that is biased in the rotational direction toward a fixed position by an elastic body provided in the sleeve. A cam is integrally provided so that the handle is elastically held at a predetermined angular position with respect to the plunger, a guide groove is provided along the axial direction on the shaft of the handle, and the guide groove A rod is integrally provided inside the rod so as to be slidable in the axial direction and around the axis, and a key that engages and disengages from the key groove provided on the sleeve side is integrally provided at the plunger side end of the rod,
The parking lot is characterized in that a knob is integrally provided at the end of the rod on the handle side, and a spring is provided that urges the rod, key, and knob toward the plunger to separate the key from the keyway. Brake operating device.
