Abstract: In a seat-rotating device that enables a seat to be rotated on a base member, a rattle-suppressing member operating in association with a lock member, which switches between the locked state in which rotation of an annular rotating member supporting a seat frame is prevented and release of the locked state, is in close contact with both a support member and the annular rotating member when the lock member is at the locked position, and a gap is created between the support member and the annular rotating member when the lock member attains the lock release position. Accordingly, it is possible to prevent the seat from rattling when it is in a stationary state and to facilitate rotation by releasing the rattle-preventing state when the seat is rotating.
