Abstract
A disc brake for use in a vehicle, such as an automobile, includes a carrier, a rotating disc having inner and outer braking surfaces, inner and outer pads, and a caliper supported in a floating condition by the carrier. The caliper has a cylinder member housing a piston for forcing the inner pad against the inner braking surface of the disc, and a claw member having a disc-passing portion straddling the disc and a claw portion for abutting against the outer pad. The cylinder member defines a through-hole extending therethrough in the axial direction of the disc. The disc-passing portion has an inner surface facing the disc and a tapped hole. A bolt member of the caliper secures the cylinder and claw members together. The tapped portion of the tapped hole is formed such that the end of the tapped portion which is remote from the cylinder member is located on the side of the cylinder member with respect to the inner braking surface. The disc-passing portion is provided with a raised portion forming a protrusion at the inner surface thereof. The protrusion extends a predetermined inward distance, with respect to the radial direction of the disc, and extends in the axial direction of the hole to the extent over which the tapped portion is formed.
