Abstract: An electric caliper includes an electric drive mechanism which generates a pressing force for pressing a friction pad against a disc rotor, and a retraction mechanism provided in a piston of a pressing mechanism. The mechanism includes a reversing member which is compressed by a force transmission portion and a pressing portion of the piston to thereby generate a reverse force. Also, the mechanism includes a movable element which relatively retracts due to the reverse force, and a first elastic member which is compressed by the movable element and the advancing force transmission portion to thereby apply a restoring force. Thus, in the mechanism, the reversing member generates the reverse force as a result of advancement of the force transmission portion, and the movable element relatively retracts due to the reverse force and compresses the first elastic member. When free rotation (no-load rotation) of a brake motor of the mechanism is permitted, the restoring force generated as a result of compression of the first elastic member is applied to the force transmission portion, whereby the piston is retracted.
