Claims

[Scope of utility model registration request]

A cylinder body having a supply and discharge hole for pressurized air, a piston that is slidably fitted into the cylinder body and biased by a spring in the direction of loosening the brake, and the rear end of the piston is rotatable in the circumferential direction. A cylindrical sheath rod with a straight keyway in the axial direction and a spiral keyway with a twist angle with respect to the axial direction formed on the outer periphery, and a screw inside the sheath rod that is rotatable in the circumferential direction. a push rod holder attached to the push rod holder, a push rod having a rear end attached to the push rod holder and a fork for connecting a Luri ring at the tip, and a push rod fitted on the outer periphery of the sheath rod so as not to be movable in the axial direction;
A first key that fits into a straight key groove is provided with a first key that protrudes inward.
a ratchet gear; a spring-biased first pawl that comes into contact with the outer periphery of the first ratchet gear to limit its reversal; A brake with a clearance adjustment mechanism consisting of a second ratchet gear in which a second key to be fitted is protruded inward, and a spring-loaded second pawl that comes into contact with the outer periphery of the second ratchet gear to limit its reversal. A brake cylinder with a gap adjustment mechanism in which a first pawl and a second pawl are biased by a spring fitted into the inner periphery of a ratchet cover in the cylinder.
