Claims

[Scope of Claim for Utility Model Registration] 1. A caliper that straddles a disc rotor and a pair of friction pads facing each other on both sides thereof at a bridge part is supported movably in the disc axial direction by a bracket fixed to the vehicle body, A pair of support arms are provided on the outer periphery of the disc rotor and are arranged side by side with a caliper in between.A pair of support arms are provided on the outer periphery of the disc rotor and are arranged in parallel with each other across the caliper. In a vehicle disc brake in which a friction pad is suspended so as to be movable in the disk axial direction by holding a provided lug, the guide surface of the pad guide portion that supports the inner surface of the lug is moved away from the disk rotor. A friction pad return structure for a disc brake for a vehicle, characterized in that the pad is inclined so as to gradually approach the disc axis. 2. A caliper that straddles the disc rotor and a pair of friction pads facing each other on both sides of the caliper is supported movably in the disc axial direction by a bracket fixed to the vehicle body, and the outer periphery of the disc rotor is attached to the bracket. A pair of support arms are extended to be arranged in parallel with the caliper in between, and ear pieces protruding from both sides of the back plate of the friction pad are held in pad guide grooves provided opposite to each other in both support arms. , in a vehicle disc brake in which a friction pad is suspended so as to be movable in the direction of the disc axis, the outer guide surface of the pad guide groove is inclined so as to gradually move away from the disc axis as it moves away from the disc rotor; For vehicles, a pad spring is compressed between the and the back plate and urges the friction pad toward the outer diameter side of the disc and presses the outer surface of the lug against the outer guide surface of the pad guide groove. Disc brake friction pad return structure. 3. A caliper that straddles a disc rotor and a pair of friction pads facing each other on both sides thereof at a bridge part is supported movably in the disc axial direction by a bracket fixed to the vehicle body, and the outer periphery of the disc rotor is attached to the bracket. A pair of support arms are installed in parallel with the caliper in between, and a pad guide section provided opposite to both support arms is provided with a retainer protruding from both sides of the back plate of the friction pad. hold the piece,
In a disc brake for a vehicle in which a friction pad is suspended so as to be movable in the disc axis direction, a guide part of a retainer that supports the outer surface of the ear piece is inclined so as to gradually approach the disc axis as it moves away from the disc rotor. A friction pad return structure for vehicle disc brakes. 4. A caliper that straddles the disc rotor and a pair of friction pads facing each other on both sides thereof is supported movably in the disc axial direction by a bracket fixed to the vehicle body, and the outer periphery of the disc rotor is attached to the bracket. A pair of support arms are installed in parallel with the caliper in between, and a pad guide section provided opposite to both support arms is provided with a retainer protruding from both sides of the back plate of the friction pad. hold the piece,
In a vehicle disc brake in which a friction pad is suspended so as to be movable in the axial direction of the disc, the retainer includes an outer guide portion that supports the outer surface of the ear piece, and urges the friction pad toward the outer diameter side of the disc, A disc for a vehicle, characterized in that it is provided with an ear piece and a pressing piece that presses the outer surface against the outer guide part, and further, the outer guide part is inclined so as to gradually move away from the disc axis as it moves away from the disc rotor. Brake friction pad return structure. 5. A pad spring is compressed between a pair of friction pads that are arranged opposite to each other with a disc rotor in between, and a bridge part of a caliper that straddles both friction pads,
For vehicles, a pressing piece disposed on the outer periphery of the disk rotor in the disk axial direction on the pad spring is brought into contact with the upper surface of the back plate of the friction pad to urge the friction pad toward the center of the disk. A friction pad return structure for a disc brake for a vehicle, characterized in that the pressing piece of the pad spring is inclined so as to gradually approach the disc shaft as it approaches the disc rotor.
