Abstract
A seat reclining device is provided, which has a base plate secured to a seat cushion; a tooth plate secured to a seatback; a center shaft for permitting the tooth plate to pivot relative to the base plate; first teeth possessed by the tooth plate; a tooth piece having second teeth which are engageable with the first teeth to establish a locked condition between the base plate and the tooth plate, the tooth piece having parallel side walls; and a guide groove defined by the base plate for slidably receiving therein the tooth piece, the guide groove having parallel guide walls which face and contact the parallel side walls of the tooth piece respectively. The parallel side walls are provided near the first teeth with respective projections which are directed toward each other. Due to provision of the projections, the locked engagement between the tooth piece and the tooth plate through the first and second teeth is assuredly kept without producing play even when a marked shock is applied therebetween.
