Claims (1)

A shaft member fixed to the main body structure, an output member loosely fitted to the shaft member, and rotatably supported by the shaft member, and the output member rotating together with the movement in the rotation direction. An operation contact portion provided at least at one position on the output member side, a wedge slope forming a wedge portion between a peripheral portion of the output member and a peripheral surface of the shaft member facing the output member; At least a pair of circular cross-section members that are located on both sides of the contact portion in the rotational direction and engage with the wedge slope to stop the reverse input rotation of the output member, and the input rotatably supported by the shaft member and the member is formed in the input member, wherein disposed opposite to the circular cross section member between the peripheral surface of the shaft member facing the peripheral surface and which of said output member, said input rotation of the input member It transmits to the said operation contact part via a circular section member And a working portion, the actuating abutments constituted by the rod-shaped member separate from the said output member, against the rod-shaped member with respect to the peripheral surface of the shaft member toward and away from the slide freely and the output A direction in which the circular cross-section member is abutted and arranged on both side surfaces of the rod-shaped member so that the rod-shaped member approaches the circumferential surface of the shaft member. The reverse input blocking device according to claim 1, wherein the circular cross-section members disposed on both side surfaces of the rod-shaped body are brought into contact with the wedge slope by the biasing force .
