Claims

[Claims for Utility Model Registration] An operating lever of a parking brake is supported by the vehicle body so as to be swingable in the longitudinal direction of the vehicle body, the operating lever is connected to a brake device of the vehicle body via a linkage, and the operating lever of the parking brake is A yoke is pivotally supported at the distal end so as to be swingable in the front and back direction, a cylindrical stem is connected to the yoke so as to be rotatable in the circumferential direction of the stem, and the stem is rotatable in the circumferential direction. and is supported by the vehicle body so as to be slidable in the longitudinal direction, and between the stem and the vehicle body, the stem is prevented from sliding forward at a position where the stem is slid backward;
Further, a locking mechanism is provided that allows the stem to be rotated in the circumferential direction to release the restriction, a release rod is inserted into the stem in the axial direction, and an operating handle is attached to the base end of the release rod. A stopper pin is provided protruding from the base end of the operating handle or the release rod, and a long hole is formed in the stem in the axial direction to restrict rotation of the release rod with respect to the stem and to limit the sliding amount within a predetermined range. The stopper pin and the elongated hole are engaged with each other so as to restrict the movement of the release rod, and the stopper pin is engaged with the elongated hole so as to restrict the movement of the release rod. , an engagement means is provided which releases the engagement when the release rod is moved rearward, and the release rod is provided with a return spring that biases the release rod toward the forwardmost position. Operation release type parking brake device.
