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. |
