A winding coil(30) is coupled with either one of the outer core and the inner core. A stator(S) is constituted of the outer core, the inner core and the winding coil. A mover(K') is inserted in the outer core and the inner core so as to be moved. The mover(K') comprises a magnet holder(50) of a cup shape having a constant outer diameter and a permanent magnet(60) formed with a ring shape and inserted in the magnet holder(50). The permanent magnet(60) is inserted and joined at the magnet holder(50) in a length direction.
