<p>PURPOSE:To prevent a caliper from clatterning in non-braking and reduce the leakage along an elastic seal, by interposing the elastic seal between the caliper and a shaft to block the slide between the caliper and the shaft by prescribed sliding resistance. CONSTITUTION:A disc brake comprises a fixed support 2 located at a disc rotor 1, a pair of friction pads 3, 4 which are tightened to each other by the rotor 1, the caliper 5 which brings one friction pad 4 into pressural contact with the disc rotor 1 by a built-in piston and brings the other friction pad 3 into pressural contact with the rotor 1 by the reaction of the former pressural contact, and support mechanisms 7, 8 which support the caliper 5 on the fixed support 2 so that the caliper 5 can move in the axial direction of the disc rotor 1. The elastic seal 13 consisting of a bushing 13a and boots 13b, 13c is iterposed between the cylinderical shaft 11 and a through hole part 5b of the caliper 5.</p> |
