ーキの制動間隙自動調整装置。[Claims for Utility Model Registration] A cup-shaped piston fitted into the cylinder so that its inner space communicates with the inside of the cylinder, and a cup-shaped piston that is non-rotatably supported by an end wall of the cylinder and whose tip end is connected to the piston. an adjustment bolt that protrudes into the inner space of the piston; an adjustment nut that is threaded onto the adjustment bolt and whose tip faces the end wall of the piston; a helical clutch spring that is locked and whose other end abuts against the flange of the adjusting nut to allow the adjusting nut to slide forward but prevent it from sliding backward; and a helical clutch spring that slides into the inner cavity of the piston. can be mated,
When the pressure-receiving area on the end wall side of the piston is large and the piston is biased against the rear end of the adjustment nut by a spring through a thrust bearing, and the brake fluid pressure of the cylinder exceeds a predetermined value. An automatic braking gap adjustment device for a disc brake, comprising a stepped piston that retreats from the adjustment nut against the force of the spring.
