Abstract

The present disclosure relates to A rotating device, comprising: a fixed disc; a movable disc rotatably provided on the fixed disc via rolling elements; a driving device configured to drive the movable disc to rotate relative to the fixed disc; wherein the driving device drives the movable disc to rotate relative to the fixed disc via a gear pair; characterized in that the rotating device further comprises: at least one restraining mechanism configured to restrict rotation of the movable disc, wherein when the driving device drives the movable disc to stop at any position, the restraining mechanism restricts rotation of the movable disc, causing the driving device to stall, so as to eliminate the gap between adjacent teeth in the gear pair. The present disclosure also relates to a seat comprising the aforementioned rotating device. The present disclosure eliminates the gap between adjacent teeth in the gear pair by causing the driving device to stall.
