ABSTRACT:
A reclining device for a vehicle seat, which has a base arm and an upper arm rotatably connected via a shaft to the base arm, with an arcuate inwardly toothed portion formed in the upper arm. A lock gear member is rotatably supported on a pin fixed to the base arm, having an outwardly toothed portion to be meshed with the arcuate inwardly toothed portion of upper arm. The lock gear member is operatively connected via a cam plate and interlocking elements to an operation lever. Thus, motion of the lock gear member is confined to rotation about the pin, without wobbling therein, and further the lock gear member is moved via those cam plate and interlocking elements by handling the operation lever so as to positively bring the outwardly toothed portion to and out of meshed engagement with the inwardly toothed portion.
