。[Claims for Utility Model Registration] A disc rotor that rotates the wheels together; an inner pad and an outer pad that are disposed to face the plate surface of the disc rotor; a torque receiving member that supports an inner pad and the outer pad and includes a bridge portion that connects a pair of support portions that support the outer pad; and two cylinder portions that each include a piston that presses the inner pad against the disc rotor. , a reaction part that has a pair of side pawls and a central pawl provided opposite to the cylinder part and presses the outer pad against the disc rotor, and is movable in a direction parallel to the axis of the disc rotor. In a caliper floating type two-piston disc brake that includes a caliper, the cross-sectional shape of the central part and both ends of the bridge part is defined by the disc rotor's radial dimensions X 1 and X 2 and the axial dimension Y 1 , Y2 is shaped so that X 1 Y 1 > X 2 Y 2 , and the central claw part is inserted between the waata pad and the central part of the bridge part. disc brake.
