Claims

[Scope of utility model registration request]

The caliper is placed across the disc rotor and a pair of friction pads facing each other on both sides.
The supporting arms of the brackets, which are arranged in parallel on the outer periphery of the disk rotor with a caliper in between, are supported movably in the disk axis direction via sliding pins, and the retainer is attached to the pad guide section provided opposite to both supporting arms. A retainer/pad spring having a pad spring section and a pad spring section is installed, and the ears protruding from both sides of the back plate of the friction pad are supported by the retainer section, and the pad pressing pieces of the pad spring section support the ears protruding from both sides of the back plate of the friction pad. In a vehicle disc brake in which a friction pad is suspended so as to be movable in an axial direction of the disc by resiliently repelling an ear piece toward the inner diameter of the disc, the pad pressing piece of the pad spring portion is used as a first pad pressing piece; A second pad pressing piece is provided on the retainer portion to face the first pad pressing piece, and the first and second pad pressing pieces are moved closer to the disk rotor. A friction pad return structure for a disc brake for a vehicle, characterized in that the ear pieces are arranged at an angle so as to approach each other, and each of the ear pieces has a tapered surface formed on the upper and lower edges thereof on the side of the disc rotor.
