Abstract
A seat reclining device has an external gear member and an internal gear member positioned in opposing relation, and a stopper member between the opposing gear members for regulating the reclining movement of the backrest relative to the seat cushion. The stopper member includes a first convex portion on the external gear (or internal gear) member and a stopper provided on the outer peripheral surface of the internal gear (or external gear) member. A second convex portion is also provided on the external gear (or internal gear) member. By engaging the second convex portion with a bore on a ring member that surrounds the periphery of the internal and external gear members, a part of the contact force between the stopper and the first convex portion is transmitted to the ring member.
