Abstract: The vehicle seat includes: a seat cushion; a seat back; a lifter link mechanism wherein the seat cushion is displaced by a sector gear being displaced; and a speed reducer-equipped motor including a pinion gear engaging with the sector gear; and a first and second restriction portions that stop the rotation of the pinion gear to one side. The sector gear is displaced to one side by the pinion gear being rotated to one side. The displacement of the sector gear to one side is stopped by the rotation of the pinion gear to one side being stopped by the first and second restriction portions. The sector gear is displaced to the other side by the pinion gear being rotated to the other side. The rotation of the pinion gear to the other side is stopped by the displacement of the sector gear to the other side being restricted.
