レーキ。 A cup-shaped piston is fitted into a cylinder formed in the caliper so as to be slidable in the axial direction via a piston seal, and this piston is pushed by a parking brake mechanism or pressurized fluid supplied into the cylinder. In the disk brake with a parking brake mechanism, the parking brake mechanism is slid in the axial direction through a seal ring into a mounting hole provided coaxially with the piston in the bottom wall of the cylinder. a bottomed cylindrical adjustment nut that is movably and fluid-tightly fitted and whose open end protrudes into the cylinder; An adjusting bolt which together constitutes a clutch, a spring interposed between the head of the adjusting bolt and a circumferential wall of the piston to bias the adjusting bolt toward the top wall of the piston, and a spring for urging the adjusting bolt toward the top wall of the piston. A thrust bearing that ensures smooth rotation, and a through hole provided in the top wall of the piston prevent it from falling out of the cylinder, and are movable in the axial direction and are assembled in a liquid-tight manner, and the adjustment is performed at the inner end. a pushing member that faces the central top surface of the head of the bolt and engages with the central top surface of the bolt head when pushed into the cylinder to constitute a second thrust bearing; and on the closed end side of the adjustment nut. a camshaft that is rotatably supported by a support portion formed on the caliper and has a cam groove facing the closed end of the adjustment nut and is rotated by a parking brake operation; The present invention is characterized by a toggle interposed between the closed ends of the adjustment nut to move the adjustment nut in the axial direction in response to rotational displacement of the cam groove and to always restrict rotation of the adjustment nut. Disc brake with parking brake mechanism.
