Claim:
1. A vehicle seat slide device adapted for a seat including a seatback, the vehicle seat slide device comprising: a lower rail and an upper rail coupled to each other in a manner movable relative to each other; a lock member that selectively allows and restricts relative movement of the lower rail and the upper rail; a memory piece located in the lower rail, wherein the memory piece is engaged with the upper rail by urging force of a memory piece urging member, and the memory piece is engaged with the lower rail by pressing force that counters the urging force; a memory link pivotally coupled to the upper rail in the upper rail, wherein the memory link releases the lock member and the memory piece with urging force of a memory link urging member, and the memory link pivots in a releasing direction to press the lock member in a pivot direction in which restriction of the relative movement is cancelled and press the memory piece against the urging force of the memory piece urging member; a slide member coupled to the upper rail in a manner movable in a direction of the relative movement, wherein the slide member releases the memory link with urging force of a slider urging member, and the slide member moves to press the memory link in the releasing direction when the seatback is collapsed forward; and a stopper member fixed to the upper rail, wherein after the seatback is collapsed forward and the upper rail is moved in a seat-frontward direction, when the upper rail is moved in a seat-rearward direction, the stopper member contacts the memory piece and restricts seat-rearward movement of the upper rail at a relative position of the lower rail and the upper rail prior to the movement.
