装置。 A fixed magnetic pole that also serves as a shaft is located at the axial center position, and is magnetized to have different polarities in the radial direction, with one magnetic pole facing the fixed magnetic pole concentrically at a predetermined interval around the fixed magnetic pole. a permanent magnet disposed along the circumferential direction; a yoke magnetically connecting the other magnetic pole of the permanent magnet to the magnetic pole; and a plastic disposed slidably in the axial direction on the fixed magnetic pole. and a movable coil wound around the coil bobbin so as to form a slight gap between the coil bobbin and the inner peripheral surface of the permanent magnet,
An electromagnetic drive device characterized in that a moving coil is driven in the axial direction by an electromagnetic force generated by an interaction between a magnetic flux generated by the permanent magnet and passing through the moving coil and a current supplied to the moving coil. .
