[Claims for Utility Model Registration] It has a sector in which a plurality of engagement teeth are formed along an arc centered on one axis, a mounting hole and an engagement claw, and the one axis is connected to the one axis in the mounting hole. It is rotatably attached to a parallel support shaft and biased with a predetermined biasing force in one direction of rotation, thereby allowing relative rotation in one direction with respect to the sector, but in the opposite direction to the one direction. The engaging pawl is engaged with the engaging tooth of the sector in a state that prevents relative rotation of the sector, and the engaging pawl resists the urging force as the parking brake operating force is applied. The pawl and the sector are rotated relative to each other in the one direction while riding over the engagement teeth, thereby braking is performed, and even when the parking brake operating force is released, the engagement pawl and the engagement teeth remain engaged. In a parking brake device of a type that maintains a braking state based on During relative rotation in one direction, the outer circumferential surface of the support shaft and the inner circumferential surface of the mounting hole are prevented from coming into contact with each other, but under braking, the outer circumferential surface of the support shaft and the inner circumferential surface of the mounting hole are elastically compressed. A parking brake device characterized by being provided with an annular elastic member made of rubber or resin that allows contact with the inner peripheral surface of a hole.
