Claims

[Scope of utility model registration request]

A member that moves substantially linearly or rotationally due to a moving biasing force when the lock is released, a rotating member that is engaged with this member and rotated, and a rotating shaft fixed to this rotating member are rotatably supported. A cylindrical bearing member is formed, and a disc-shaped flange is formed at the base of the rotating shaft of the rotating member and a cylindrical mouth of the cylindrical bearing member, and a plurality of cylindrical parts concentric with the rotating shaft are formed on the flange surface. The cylindrical parts are formed so as to fit each other, and the viscous oil interposed between the rotating shaft and the cylindrical bearing member to obtain a damper effect does not leak to the outside. A damper device featuring:
