A seat reclining apparatus includes a folding operation lever displacing a reclining lock mechanism to a lock release position. When the folding operation lever is operated to a folding operation position, the reclining lock mechanism is displaced from a lock position to the lock release position. A seatback is displaced to a folded position by a biasing force of a folding biasing unit. A neutral position returning unit that retains a releasing lever disposed between the folding operation lever and the reclining lock mechanism when the seatback is inclined forward beyond a predetermined neutral position, and does not retain the releasing lever when the seatback is inclined rearward beyond the neutral position is further provided. A configuration for returning the seatback to the neutral position can be provided by a simple structure and only a slight design change at a lower production cost, and assembling is performed simply.
