Claims

[Claims for Utility Model Registration] A bottomed cylindrical piston facing the back surface of the friction pad is slidably fitted into the cylinder of the cylinder housing with the open end of the piston facing the bottom of the cylinder. On the back side, a combined body of a first strut and a second strut screwed together is interposed in the cylinder in the disk axial direction, so that the first strut is slidable in the cylinder housing but not rotatable. When the second strut is pressed against the rear surface of the piston and the piston presses the friction pad toward the disk, the amount of displacement of the piston is equal to or greater than a predetermined value;
In the disc brake in which the second strut rotates with respect to the first strut and the total length of both struts is increased, the first strut is a cylindrical body having a female threaded portion on its inner peripheral surface, and A disc brake characterized in that the second strut is attached to a solid shaft having a male threaded portion corresponding to the acid threaded portion on the outer circumferential surface of the second strut.
