Abstract

PURPOSE: To suppress a vibration, noise and a torque loss or the like by providing constitution of a pair of rotor magnets fixed into center holes of the first/ second stators and a rotor shaft screwed to a lead screw.
CONSTITUTION: A center hole is formed in the first stator 20 to rotatably fix a rotor magnet 42 into the inside. A center hole is formed in the second stator 28 to rotatably fix a rotor magnet 44 into the inside. The rotor magnets 42, 44 are set up on both sides of a lead screw 52 of a rotor shaft 36 and fixed in a position corresponding to the center holes of the stators 20, 28. A nut 50 is screwed to the lead screw 52 engraved in the center part of the rotor shaft 36. When the lead screw 52 is turned, the nut 50 and a movable part 57 are linearly moved in a direction of the axial line of the rotor shaft 36 by a length determined by a product of a pitch and a number of turns of the lead screw 52.
