Patent number: 11493098Abstract: Provided are a one-way clutch and a rotary damper device equipped with the one-way clutch, in which size reduction can be achieved. A claw of a slide member has a retreat surface that abuts against an internal tooth of an outer member when the outer member turns toward one side with respect to an inner member and an engagement surface that abuts against the internal tooth when the outer member turns toward the other side with respect to the inner member. When the internal tooth and the retreat surface abut against each other, the slide member slides in a sliding direction, thus causing the claw to retreat from the internal tooth, and the outer member turns independently of the inner member. When the internal tooth and the engagement surface abut against each other, the internal tooth and the engagement surface are engaged, and the outer member and the inner member integrally turn.Type: GrantFiled: December 27, 2017Date of Patent: November 8, 2022Assignee: SIMOTEC CO., LTD.Inventor: Yorikazu Yasui
