ブレーキシリンダのオートアジャスト装置。A hydraulic chamber defined by a piston that is slidably fitted into a cylinder and an opposing part thereof, and an adjustment bolt with a clutch surface is screwed into a nut member fixed to the opposing part with a multi-thread screw. However, in an auto-adjustment system for a vehicle brake cylinder in which this adjustment bolt is constantly pressed in the direction of the piston by an adjustment spring so that the clutch surface of the adjustment bolt is brought into contact with the clutch receiving surface of the piston, the adjustment bolt has a rear end. A hole is drilled in the direction of the axial force to be opened, and the actuator is tightly and slidably fitted into the hole via a spring, and the tip of the actuator protruding from the hole is held by the adjust spring. When the piston comes into contact with a spring retainer that is biased toward the piston and a hydraulic pressure higher than the set value is generated within the cylinder,
For a vehicle, the actuator is provided with an over-adjustment prevention mechanism in which the actuator sinks into the hole against the spring, presses the spring retainer outward from the center of the adjustment bolt, and restricts rotation of the adjustment bolt. Brake cylinder automatic adjustment device.
