ーキ用間隙自動調整装置。[Claims for Utility Model Registration] A piston with a bottom at the front end that slides in the rotor axial direction by the hydraulic pressure in the cylinder of the caliper and presses the friction pad against the disc rotor; an adjusting nut that is movable in the rotor axial direction and is non-rotatable, which is carried along when the piston moves toward the rotor under pressure; a first biasing nut that biases the adjusting nut toward the rotor;
a spring member, a first sleeve member provided so as to be relatively screwable and rotatable in a direction away from the rotor from the adjustment nut, and a first sleeve member disposed so as to be unrotatable in a direction away from the rotor. A second sleeve member is inserted between the first sleeve member and the second sleeve member, and a second spring member is inserted between the first sleeve member and the second sleeve member. and an overtravel piston supported so as to be able to press and abut at all times through the piston, and when the hydraulic pressure in the cylinder is below a predetermined value, the overtravel piston is moved by the forward force of the adjusting nut as the piston moves forward. The first sleeve member is released from the pressing contact against the spring force of the second spring member, and the first sleeve member is allowed to rotate out of the cylinder, and the liquid in the cylinder exceeds the predetermined value. An automatic gap adjustment device for a disc brake, characterized in that, when pressure is applied, the press contact is maintained to prevent the first sleeve member from rotating out of the screw.
