Claims

[Scope of utility model registration request]

a plunger supported movably and rotatably in an axial direction by a part of the vehicle body and connected to a brake mechanism of a parking brake; and a plunger pivotally mounted to a part of the vehicle body so as to be swingable and biased by a spring, and an outer periphery of the plunger. A pawl that releasably engages with a tooth provided on one side, and a handle that is provided at the rear end of the plunger and that pulls the plunger backward and rotates the plunger, and when the handle is pulled, the The plunger is moved rearward to activate the brake mechanism, and is engaged with the pawl to be locked at the moved position, and by rotation of the handle, the plunger is rotated to release the engagement with the pawl. In the parking brake operating mechanism that returns the plunger to its original position to release the operation of the brake mechanism, the handle is configured separately from the plunger, and the handle has a rear part of the plunger. A cylindrical shaft part that is movable and rotatably assembled in the axial direction is provided on the outer periphery of the end part, and a straight groove extending in the axial direction is provided inside the shaft part, and a straight groove extending in the circumferential direction from one end of the straight groove is provided. An annular groove that extends and has a valley at one end of the straight groove is provided, and a hole extending along the axis and opening at the rear end of the plunger and a radial hole perpendicular to the hole are provided at the rear end of the plunger. A steel ball is assembled into the hole, which is pushed outward by the rod inserted in the large direction, and a part of the steel ball is fitted into a part of both the grooves, and a steel ball of the handle is inserted between the handle and the plunger. An operating mechanism for a parking brake, characterized in that a spring is installed that allows rotation relative to the plunger and biases the handle in the axial direction so that the steel ball comes into contact with one end of the linear groove.
