PROBLEM TO BE SOLVED: To prevent damage of a shim board resulting from an positional error upon the assembling to a carrier. SOLUTION: Since an outer peripheral part 530 of a stopper part 53 of a shim board 50 is positioned outer than an inner peripheral part 531 thereof in relation to a tangential direction of a disc from a pawl side 42, the shim itself receives a force transmitted from a caliper 40 at assemblage and is adjusted in its position.
