ンダ。 A cylinder body attached to the bucking plate, a hydraulically actuated piston slidably fitted in the cylinder body, and an end rotatably fitted in the center hole of the piston and protruding outside the cylinder body. an adjusting nut integrally having a ratchet wheel at the end; an adjusting bolt screwed into the adjusting nut and engaged so as not to rotate relative to the end of the brake shoe; and an adjusting bolt pivotally connected to the cylinder body. and an adjustment lever having a pawl that engages with the teeth of the ratchet wheel, and a connecting plate provided to move integrally with the piston,
A notch extending from the other end toward one end is formed in the connecting plate, and an abutment portion that is inserted into the notch and can come into contact with the end of the notch is formed on the adjustment lever, and this abutment portion and the notch In a wheel brake cylinder in which a tension coil spring is tensioned between a connecting plate and an adjustment lever so that the terminal ends thereof are brought into contact with each other, a sliding movement of the piston toward the outside of the cylinder body is applied to the surface of the cylinder body and the adjustment lever. When the amount of rotation of the adjustment lever due to the movement reaches a set maximum rotation amount that is smaller than the amount of rotation that would cause distortion between the abutting portion of the adjustment lever and the notch of the connecting plate, the adjustment levers contact each other and are further rotated. A wheel brake cylinder is formed with a pair of abutting portions that prevent rotation.
