Claims

[Scope of utility model registration request]

In a disc brake that has an anchor pin that is inserted and screwed between the boss parts of the caliper body, a screw for fixing the anchor pin to the caliper body is attached to the first arm of the fixture consisting of the first arm, the second arm, and the body. A notch for receiving the cylindrical portion of the anchor pin is provided in the second arm of the screw, and the inner surface of the second arm of the fixing tool is brought into contact with the inner surface of the boss of the caliper body, and the threaded portion is attached to the threaded portion of the screw. A structure that prevents the anchor pin from being removed, which is characterized by tightening the tip of the adjustment bolt that is threaded onto the top surface of the head of the anchor pin.
