Notches 20, 20 constituting engaging portions are provided at portions of middle portions in a rotating direction a rotor at end portions on outer radial side of the two pads 11, 12 in a radial direction of the rotor. Further, an engaging pin 19 is made to bridge an outer body portion 3 b and an inner body portion 4 b constituting the caliper 5 b. Further, the coupling pin 19 is inserted through the notches 20, 20 , so that the two pads 11, 12 are displaceable in an axial direction of the rotor, and a braking torque applied to the two pads 11, 12 can be supported by the coupling pin 19.
