A parking mechanism part () including a clamp member () and a thrust generation mechanism () is integrally arranged in a caliper () constituting an opposed-piston type disk brake (). The clamp member () is supported on the caliper () to be movable along the axial direction with respect to an inner body part () of the caliper (), a spindle () of the thrust generation mechanism () is rotatably supported on the base part () of the clamp member (), a nut () threadedly engaged with the tip end of the spindle () is arranged inside a combined-use piston () fitted in an enter-side inner cylinder ().

Opposed-piston type disk brake device

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.
