Provided is a seat reclining device configured so that a spring cover for covering a lock spring for rotating and pressing a rotatable cam can be easily and reliably mounted to the outer surface of either a base plate or a ratchet plate. A seat reclining device is provided with: a lock spring (68) for rotating and pressing a rotatable center shaft (51) in the direction in which a rotatable cam (47) is rotated to the lock position side, the lock spring (68) being either disposed so as to face the outer surface of either a base plate (27) or a ratchet plate (57), or disposed within a hole formed in either the base plate or the ratchet plate; and a spring cover (72) for covering the lock spring and disposed so as to face the outer surface of either the base plate or the ratchet plate. The inner surface of one of a seat cushion-side frame (13) and a seat back-side frame (16) is made to be in contact with the outer surface of a protrusion (76) protruding from the spring cover. |
