Abstract
A reclining device for a vehicle seat, which has 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 having an outwardly toothed portion is movably supported by two guide elements in a diametrical direction of a circle along which the arcuate inwardly toothed portion is formed, to thereby insure a full meshed engagement between the outwardly and inwardly toothed portions. The lock gear member is operatively connected via a cam plate and interlocking elements to an operation lever. The interlocking elements include enagement pin and elongated guide hole which are coacted by rotation of the operation lever so as to guide the lock gear member in such diametrical direction. Additionally, a non-circular engagement may be arranged between the shaft and upper arm to prevent rotation of the shaft, and a connecting tubular member may be connected coaxially to the shaft.
