Claims

[Scope of utility model registration request]

(1) A cylinder body having a pressure air supply/discharge hole, a piston that is slidably fitted in the cylinder body in the axial direction and is biased by a spring in the direction of loosening the brake, and a rear end of the piston in the axial direction. a sleeve that is rotatably attached and whose axial front end protrudes outside the cylinder body and moves back and forth together with the piston; a push rod that is rotatably screwed into the sleeve and has a brake shoe connected to its front end; The push rod is attached to a key groove provided in the axial direction on the outer periphery and a through hole provided in the radial direction in the front end of the sleeve so as to be able to move forward and backward, and the tip engages with the key groove to prevent rotation of the push rod. A brake cylinder for a railway vehicle comprising an engaging member that allows the push rod to move back and forth, and an adjustment section for rotating the sleeve provided at the front end of the sleeve.

(2) A brake cylinder for a railway vehicle according to claim 1, wherein the engaging member also serves as the adjusting portion.
