を特徴とするデイスクブレーキ。[Scope of Claim for Utility Model Registration] A pair of friction pads arranged to face each other on the outer periphery of a disc rotor, a caliper arranged so as to straddle the pair of friction pads and the outer periphery of the disc rotor, A pair of pistons arranged in the cylinder portion of the caliper in a state lined up in the rotating direction of the outer peripheral portion of the disc rotor, and a ring-shaped elastic member each having an inner peripheral surface that is constant to the pair of pistons. a retract member that is fitted under the frictional force of and has an outer peripheral portion fixed to the inner wall of the cylinder portion, and when the piston is pushed out by the supply of brake fluid pressure to the cylinder portion, the retract member In a disc brake of a type in which a member elastically deforms to store a restoring force, and when the hydraulic pressure is released, the piston is returned to a non-operating position by the restoring force, on the rotation side of the outer periphery of the disc rotor. A disc brake characterized in that the amount of elastic deformation of a retract member fitted to a piston is set to be larger than that of the other retract member.
