ABSTRACT:
An actuator includes: a rotary shaft allowed to axially and including a threaded portion at a protruding portion thereof and two idle regions disposed respectively at both ends of the threaded portion; a movable structure adapted to travel along the rotary shaft; a stopper means facing the end of the protruding portion of the rotary shaft and configured to restrict the axial movement of the movable structure located at the idle region; an open space disposed between the stopper means and the end of the rotary shaft and configured to allow the rotary shaft to axially move; an urging means for urging the movable structure toward the motor; and a recovery means for urging the movable structure toward the threaded portion by a magnetic thrust force exerted by cutting off power supply to the motor when the movable structure is in contact with the stopper means.
