Claims

[Scope of utility model registration request]

a full rake disc that rotates integrally with the wheel; a brake pad that has a friction material that presses the peripheral surface of the brake disc on one side and a backing metal on the other side; the brake pad is supported by the backing metal; A torque receiving member that transmits braking torque of a wheel from a brake pad to a vehicle body side, and a caliper that moves relative to the torque receiving member so as to move the brake pad toward the circumferential surface of a brake disk by a piston fitted therein. The torque receiving member is provided with an overhang for receiving the braking torque acting on the brake pad, and the overhang is such that the input direction of the braking torque is aligned with the center position of the piston. A disc brake characterized by being arranged so as to almost match each other.
