摘要

A seat reclining apparatus is provided with a neutral position returning means which holds a link lever at a forward reclining operating position, and releases the holding of the link lever in the case that a seat back is shifted from a forward reclined position side to a neutral position within a reclining range. The neutral position returning means shifts a cam plate (15) by a spring in such a manner as to hold the position of the link lever (13) at a lever rotating position while the link lever rotates a releasing lever (12) fixed to a center shaft of a reclining lock mechanism together therewith so as to release a lock of the reclining lock mechanism , and shifts the cam plate to an original position against the spring by a cam releasing means so as to return the link lever to an original position, in the case that the forward reclining seat back (3) is shifted to the neutral position.
