a lock plate configured to rotate about a rotation shaft as a center while being hooked to the lower arm stopper in a process of reclining forward together with the seatback with respect to the reclining hinge shaft as the center;
a folding link configured to be limited to rotate by being hooked to the lock plate and configured to make folding rotation together with the seatback with respect to a folding hinge shaft, as a center, located at a part above the reclining hinge shaft, by being released from being hooked to the lock plate according to the rotation of the lock plate; and
a lever configured to manipulate a reclining or folding operation of the seatback,
wherein according to a manipulation of the lever, locking between the seatback and the seat cushion is released so that the lock plate and the folding link together with the seatback rotate forward about the reclining hinge shaft as the center,
with the reclining hinge shaft as the center, a guide pin is fixed at another predetermined radial position of the lower arm, and
a guide hole of a long hole into which the guide pin is inserted extends along a rotation path of the lever in the lever, thereby allowing the lever to rotate in a guide hole section.
