Claims

[Scope of utility model registration request]

A cylinder body having a supply/discharge hole for pressurized air, a piston that is slidably fitted into the cylinder and biased by a spring in the direction of loosening the brake, and the rear end of the piston rotates in the circumferential direction. A cylindrical sheath rod that can be freely attached and has a linear keyway in the axial direction and a spiral keyway with a twist angle with respect to the axis formed on the outer periphery, and a cylindrical sheath rod that can be freely rotated in the circumferential direction inside the sheath rod. a screwed push rod holder, a push rod whose rear end is attached to the push rod holder and a fork for connecting the $1 ring at the tip, and a push rod that is fitted onto the outer periphery of the sheath rod so as not to be movable in the axial direction;
A first key that fits into the linear key groove projects inward and is biased by a spring from the outside of the first ratchet gear and comes into contact with the outer periphery of the first ratchet gear to limit its reversal. a second ratchet gear which is fitted onto the outer periphery of the sheath rod so as not to be movable in the axial direction and has a second key protruding inwardly which is fitted into the helical keyway; and an outer side of the second ratchet gear. In the brake cylinder with a clearance adjustment mechanism, the helical keyway on the outer periphery of the sheath rod is biased by a spring and a second pawl that comes into contact with the outer periphery of the second ratchet gear to limit its reversal is provided. A gap adjustment having a relief groove formed of a relief portion formed in the axial direction starting from the position on the spiral portion of the second key at the time, and a return portion returning from the starting end of the relief portion to the spiral portion. Brake cylinder with mechanism.
