Claims

[Claims for Utility Model Registration] A main body provided between a brake chamber and a brake operating shaft, a driving member movable with respect to the main body and positioned on the brake operating shaft by the main body, and the main body. for a vehicle brake, comprising: a lever arm pivotally mounted to the vehicle; and adjustable coupling means between the lever arm and the drive member for adjusting the relationship between the drive member and the body. a slack adjustment device comprising: means for coupling a brake rod with a generally cylindrical aperture to the lever arm; a bushing having a generally cylindrical outer surface and a mating groove formed in the outer surface within the bore; and extending through the lever arm opposite the mating groove. a bushing extending from the outside of said lever arm through a cavity provided to a preventing pin, the pin having a locking pin for supporting the pin within the cavity;
a large head at one end abutting the outer surface of the lever arm and attachment means extending through the other end of the pin to thereby prevent rotation of the bushing within the aperture of the lever arm; Further, a reinforcing shoulder is provided at one end of the hole for holding the bushing, and the pin prevents the bushing from coming out of the lever arm in one direction. Movement of the bushing in the direction is adapted to be supported by the shoulder of the brake rod connection device to the lever arm of the automatic slack adjuster.
