发明名称 VEHICLE DISC BRAKE
摘要 A pad retainer of a vehicle disc brake includes: a pair of retainer portions mounted in pad guide grooves; a connecting piece connecting the pair of retainer portions together; and pad returning portions configured to bias the friction pads to a side opposite to the disc rotor. Each of the pad returning portions includes an elastic loop portion formed into an arc shape by bending a narrow elongated piece, which extends in a direction opposite to the disc rotor from an inner side in a disc radial direction of a deep side piece of the retainer portion, and then back towards the disc rotor; and a holding portion extending from a bent-back end of the elastic loop portion towards the disc rotor and configured to hold a lug piece of the friction pad.

主权项 1. A vehicle disc brake comprising: a pair of caliper supporting arms provided on a caliper bracket which is fixedly provided on a vehicle body, the pair of caliper supporting arms extending over an outer edge of a disc rotor in a disc axis direction; pad guide grooves provided in the caliper supporting arms so as to face each other; and lug pieces projecting from both side portions of a shoe of each of a pair of friction pads disposed to sandwich the disc rotor, the lug pieces movably supported in the pad guide grooves by pad retainers, each of the pad retainers including a pair of retainer portions mounted in the pad guide grooves on both sides of the disc rotor,a connecting piece extending over the outer edge of the disc rotor and connecting the pair of retainer portions together, andpad returning portions configured to bias the friction pads to a side opposite to the disc rotor, wherein each of the pad returning portions includes an elastic loop portion formed into an arc shape by bending a narrow elongated piece, which extends in a direction opposite to the disc rotor from the retainer portion, and then back towards the disc rotor, anda holding portion extending from a bent-back end of the elastic loop portion towards the disc rotor and configured to hold the lug piece, and the friction pads move in the disc axis direction while the holding portions hold the lug pieces.
