Claims

[Scope of utility model registration request]

A caliper disposed straddling the disc rotor is supported by a bracket so as to be movable in the disc axial direction, and pad latching portions are opposed to each support arm of the bracket placed on both sides of the caliper on the outer periphery of the disc rotor. A disc brake for a vehicle that is provided with a retainer attached to the pad latching part, and suspends the ears of friction pads that are arranged opposite to each other across a disc rotor to guide the friction pads so as to be movable in the axial direction of the disc. In this method, guide pieces are provided on both sides of each friction pad to protrude toward the disk rotor, and the tip surfaces of these guide pieces are formed into tapered surfaces that are inclined with respect to the side surfaces of the disk rotor.
A pair of pad return pieces for repelling the friction pads in the anti-disc direction are provided on each of the retainers, protruding from the disk rotor side in the anti-disk direction, and the pad return pieces are brought into contact with the tapered surfaces of the guide pieces, respectively. A friction pad return structure for vehicle disc brakes.
