Abstract
Two shim plates provided for a friction pad are arranged to be slidable relative to each other in the circumferential direction of a disk, thereby suppressing the transmission of rotational force from the disk to a caliper through the friction pad and so forth during a braking operation. A friction pad including a lining and a backing plate is disposed between the disk and an outer leg portion of the caliper. An inner shim plate is integrally mounted on the back of the backing plate. An outer shim plate is disposed between the inner shim plate and the outer leg portion of the caliper in such a manner as to be slidable relative to the inner shim plate in the circumferential direction of the disk. During a braking operation, when the friction pad pressed by the caliper is circumferentially displaced by being dragged by the disk, the inner shim plate, together with the friction pad, slides relative to the outer shim plate, thereby reducing rotational force transmitted from the disk to the caliper.
