Abstract: An electromagnetic actuator including a coil; a non-movable part constituted by a magnetic substance and disposed on one side relative to the coil; and a movable part including a permanent magnet on the other side relative to the coil. Applying a current to the coil alternately generates first and third driving forces to move the magnet and the movable part to one and the other sides in a first direction relative to the coil and the non-movable part. As the movable part moves from a neutral position to the one side in the first direction, a portion of the magnet positioned on the one side in the first direction relative to the first end of the first non-movable part gradually enlarges and is magnetically attracted toward the non-movable part.
