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 brake mechanism, the handle is configured separately from the plunger, and the handle includes a rear end portion of the plunger. A cylindrical portion that is slidably fitted on the outer periphery is provided, and the cylindrical portion has a guide groove extending in the axial direction and a cam groove extending diagonally rearward from the front end of the guide groove in a direction opposite to the direction in which the handle is rotated. A pin is provided at the rear end of the plunger that penetrates through both the grooves and protrudes outward, and a cylindrical portion of the handle is connected to the outer periphery of the rear end of the plunger with a compression spring interposed at its bottom. operation of the parking brake, characterized in that the compression spring urges the handle rearward to elastically engage the pin with the front end portions of both grooves in the cylindrical portion. mechanism.
