ートアジャスト装置。A nut member is fixed to the opposing part of the hydraulic chamber defined by the piston slidably inserted into the cylinder and the opposing part, and an adjustment bolt having a stepped cylinder therein is installed as described above. A piece member is screwed into the nut member with a multi-thread screw and is connected to the clutch surface of the piston, and is provided in the front part of the adjustment bolt so that rotation is regulated and movable in the axial direction, and an actuator is provided in the stepped cylinder. The actuator is tightly and slidably fitted via a spring, and the front end of this actuator is brought into contact with the piece member, while the rear end protruding shaft part is brought into contact with a retainer that is biased toward the piston by an adjustment spring. , when a hydraulic pressure higher than a set value is generated in the hydraulic pressure chamber, the actuator moves forward to move the piece member in the axial direction and press it against the clutch surface of the piston, thereby regulating the rotation of the adjustment bolt. An auto-adjustment device for a vehicle brake cylinder, characterized in that it is designed to prevent over-adjustment.
