ABSTRACT:
A reclining device for vehicle seats utilizes a differential reduction gear (A) and a small size high speed motor (27) as a drive source, wherein one gear (10) having a plurality of slots (15) positioned radially outwardly from the axis of the gear is between another gear (16) having a corresponding number of slots (20) in alignment with the slots (15) in the one gear and a bracket (22) associated with the other gear (16) and held in position by rivets (12,21) through the aligned slots in the two gears to thereby regulate the adjustment range of the reclining angle. The motor output shaft (27a) and reduction gear (A) are connected by a resilient joint (35), a resilient member (32) is interposed between the motor and coupling (33) or between the coupling and reduction gear (A) to prevent oscillation and noise, and a coiled spring (43) acts on one end of the worm shaft (30a) of the reduction gear to prevent play between a worm (30 ) and worm gear (29).
