A seat reclining apparatus for a vehicle includes a lower frame supporting a seat cushion of a seat for the vehicle, a lower plate mounted on the lower frame, an upper plate rotatably supported by the lower plate, an upper frame supporting a seatback of the seat for the vehicle and rotatably supported by the lower frame via the upper plate and the lower plate, the upper frame being relatively rotatable with respect to the upper plate, a first lock mechanism arranged between the lower plate and the upper plate, the first lock mechanism permitting and restricting a relative rotation of the upper plate to the lower plate, a second lock mechanism arranged between the upper frame and the upper plate, the second lock mechanism permitting and restricting a relative rotation of the upper frame to the upper plate, and a stopper member rotatably supported by the lower frame and frictionally engageable with the upper plate, the stopper member applying a resistance force to the relative rotation of the upper plate to the lower plate.
