ーキ。[Claims for Utility Model Registration] A caliper having a cylinder bore that opens in one direction, and an adjustment bolt that is fitted into the cylinder bore and reciprocated in the axial direction in conjunction with the operation of the parking brake operating member. A piston that is pushed out through an adjusting nut, a peripheral wall into which the adjusting bolt is inserted, an inward flange formed at one end of the peripheral wall, and an outward flange formed at the other end of the peripheral wall. a spring receiver fixed to the inner circumferential surface of the cylinder bore or an inner circumferential surface separately provided on the inner circumferential side of the inner circumferential surface; A parking type that includes a spring provided on the outer peripheral side of the adjusting bolt between the inward flange of the spring receiver and the adjusting bolt, and urging the adjusting bolt in a direction opposite to the direction in which the piston is pushed out. In a disc brake equipped with a brake mechanism, a plurality of first engagement protrusions that protrude inward in the circumferential direction are provided on the inner circumferential surface of the cylinder bore or on an inner circumferential surface separately provided on the inner circumferential side of the inner circumferential surface. are integrally provided at predetermined intervals, and the outward flange of the spring receiver is configured to have a plurality of second engaging protrusions that protrude toward the outer circumferential side of the peripheral wall at predetermined intervals in the circumferential direction, After inserting the spring receiver into the cylinder bore until the second engagement protrusion passes through the first engagement protrusion in a state where the second engagement protrusion is positioned between the plurality of first engagement protrusions in the circumferential direction, the spring receiver is inserted. By rotating a predetermined angle around the axis, the first engagement protrusion and the second engagement protrusion can be engaged in a direction parallel to the axis of the cylinder bore, while the first engagement protrusion and the second engagement protrusion can be engaged with each other in a direction parallel to the axis of the cylinder bore. The second engaging protrusion prevents rotation of the spring receiver about the axis when the second engaging protrusion is engaged with the second engaging protrusion in a direction parallel to the axis of the cylinder bore according to the biasing force of the spring. A disc brake equipped with a parking brake mechanism, characterized in that the parking brake mechanism is provided on at least one of the first engagement protrusion and the second engagement protrusion.
