Abstract
A reclining device includes a guide bracket that is fixedly attached to one of a seat cushion and a seatback, an internal gear that is fixedly attached to the other and is shiftable for relative rotation to the guide bracket, at least a pair of lock gears that are respectively movable along a guide part provided on the guide bracket and includes external teeth meshable with internal teeth of the internal gear, and a cam that shifts the lock gears along the guide part between a lock position at which the relative rotation is regulated and an unlock position to release lock. The external teeth of the lock gear each have a shape including an indentation portion on a tooth surface closer to the guide part in a tooth thickness direction so as to define a gap between the tooth surface closer to the guide part and an internal tooth of the internal gear when the lock gears are in the lock position.
