A recliner adjuster for adjusting an inclination of a seat back with respect to a seat cushion includes a guide bracket (2) to be secured to one of the seat cushion and the seat back, an internal gear (3) to be secured to the other of the seat cushion and the seat back, a cam (6) interposed between the guide bracket and the internal gear, a pair of lock gears (4) interposed between the guide bracket (2) and the internal gear (3) so as to be radially slidable in association with movement of the cam (6), and a mounting ring (7) for mating the guide bracket (2) and the internal gear (3) with each other with the cam (6) and the pair of lock gears (4) accommodated therein. The mounting ring (7) has a generally flat annular portion (7a), a cylindrical side portion (7b), and a plurality of bent portions (7d) formed at a distal end of the cylindrical side portion (7b). The guide bracket (2) and the internal gear (3) are sandwiched between the generally flat annular portion (7a) and the plurality of bent portions (7d) of the mounting ring (7), and an outer peripheral surface of the internal gear (3) is held in sliding contact with an inner surface of the cylindrical side portion (7b) of the mounting ring (7), thereby radially positioning the internal gear (3). |
