Claims

[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 that is reciprocated in the axial direction in conjunction with the operation of the parking brake operating member when the parking brake is applied. A piston that is pushed out through an adjusting nut screwed into the bottom wall, a bottom wall through which the adjusting bolt is inserted, and a side wall extending from the outer circumferential side of the bottom wall in a direction substantially parallel to the axis of the bottom wall. The side wall has a cylindrical shape with a bottom, and the end of the side wall opposite to the bottom wall is immovable at least in the direction toward the opening of the cylinder bore or on the inner peripheral side of the inner peripheral surface. is inserted between a spring receiver attached to an inner circumferential surface provided separately from the spring receiver, and the adjusting bolt inserted through the bottom wall of the spring receiver, and the adjusting bolt is inserted in the direction in which the piston is pushed out. In a disc brake equipped with a parking brake function including a spring that biases in the opposite direction, the inner circumferential surface is attached 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. An annular retaining surface extending toward the outer circumferential direction is provided at an end opposite to the side wall and bottom wall of the spring receiver, and is inclined with respect to the axis of the cylinder bore, and is located on the outer circumferential side and at the end opposite to the bottom wall side of the spring receiver. The cylinder bore is characterized by being integrally provided with engaging protrusions that protrude toward the opening side of the cylinder bore so as to be engaged with the locking surface by a snap action when the cylinder bore is pushed in a predetermined distance from the opening side of the cylinder bore. Disc brake with parking brake function.
