Abstract: A composite disc rotor includes a disc main body, a coupling bracket and coupling units. Each of the coupling units includes a bobbin, a clip and a coupling bolt. A head part of the bobbin includes a torque receiving portion inserted in the notch and a projection projected in a circumferential direction from an end of the torque receiving portion. A pipe part of the bobbin is extended from the head part and is fitted in a coupling through hole of the disc main body. The clip includes a connecting portion between the torque receiving portion and the notch and a pressing portion extended from the connecting portion between the head part and the coupling bracket. The coupling bolt is inserted into each of through hole of the bobbin to fix the coupling bracket to the coupling unit.

Abstract: An object of the present invention is to provide a floating caliper type disc brake which can effectively suppress the occurrence of uneven wear in linings of respective pads, and effectively suppress the occurrence of noise and judder during braking. In the present invention, a caliper is supported by a support member displaceably in an axial direction of a rotor. Pressed-side shim plates are respectively lined on reverse surfaces of back plates of pads supported by the support, while supporting-side shim plates are lined on an inner side surface of a claw portion and on a distal end face of a piston. The pressed-side shim plates and the pressing-side shim plates are respectively retained by mating members to be lined on by means of resilient retainers, and one surface of each of the mutually opposing pressed-side shim plates and one surface of each of the pressing-side shim plates are slidably abutted against each other.
