Claims

[Scope of utility model registration request]

The caliper, which is placed across the disk rotor, is supported movably in the disk axial direction via a sliding pin on both support arms of a bracket that is arranged in parallel on the outer periphery of the disk rotor with the caliper in between. A retainer is attached to each of the pad latching portions provided opposite to each other on the arm, and from the retainer, an ear piece protruding from the side of the back plate of the friction pad which is disposed opposite to each other with the disc rotor in between is suspended. , a disc brake for a vehicle in which both friction pads are movably guided in the disc axial direction, wherein the retainer is provided with a guide groove in the disc axial direction, and a plurality of unidirectional teeth are provided on both sides of the guide groove. A pair of opposing slide plates are inserted with the inclined surfaces of the one-way teeth facing the disk rotor side, and a set of opposing one-way teeth of each slide plate is elastically supported in the guide groove. A pair of protruding pawls are provided on each slide plate to permit movement of the slide plate in the direction of the disc rotor, while restricting movement in the direction opposite to the disc rotor. A friction pad return structure for a disc brake for a vehicle, characterized in that a pad return piece is protruded to urge the friction pad in an anti-disc direction.
