A reclining device comprises a housing fixed to a seat cushion of a seat, a shaft connected to a seat back, and a locking member. A helical thread groove is formed in the outer peripheral surface of the shaft. The locking member has thread ridges that can engage the shaft. The locking member is movable between a lock position in which the thread ridges engage the thread groove of the shaft and an unlock position in which the thread ridges are disengaged from the thread groove of the shaft. The locking member is held in the lock position by means of a cam member that is urged toward a first position by means of a spring. The locking member can be moved to the unlock position when the cam member is moved to a second position.
