グ機構付デイスクブレーキ装置。[Claims for Utility Model Registration] A caliper piston is slid onto the caliper cylinder to define a hydraulic chamber connected to the master cylinder, and the caliper is configured to support a rotating shaft rotated by a parking lever. This rotary shaft is connected to the inner end wall of the caliper piston via an automatic brake gap adjustment device disposed in the hydraulic chamber, and the automatic brake gap adjustment device An adjusting bolt that integrally includes a non-rotatable sleeve piston that is pushed in the axial direction, and a movable clutch portion that frictionally engages with a fixed clutch portion of the sleeve piston by hydraulic pressure in the hydraulic pressure chamber, and the adjusting bolt. an over-adjustment prevention spring that biases the adjustment nut in the direction of contact with the caliper piston; In a disc brake device with a parking mechanism, which is equipped with a spring that is compressed between the inner wall of a hydraulic pressure chamber and an adjustment bolt via a spring retainer to determine the adjustment start hydraulic pressure, the bore diameter of the cylinder in which the caliper piston slides is fitted. has a diameter larger than the bore diameter of the cylinder that accommodates the sleeve piston, and the inner wall of the cylinder on which the caliper piston slides has a stepped portion for restricting movement of the spring retainer in the caliper piston braking direction, and the stepped portion and the sleeve piston are connected to each other. 1. A disc brake device with a parking mechanism, characterized in that a tapered surface is formed at the boundary between cylinders to be accommodated, and a spring retainer is positioned at the boundary.
