PROBLEM TO BE SOLVED: To suppress the behavior of a caliper body by ensuring mounting strength on the disc turning-in side in radially mounting the caliper body to a vehicle body. SOLUTION: A screw length B2 of an external screw part 6a and an internal threaded hole 3d on the disc turning-out side of a caliper body is made almost the same as the conventional length, while a screw length B1 of an external screw part 5a and an internal threaded hole 3c on the disc turning-in side is set longer than the screw length B2. Mounting structure on the disc turning-in side of the caliper body 2 is thereby enhanced with simple structure.
