PROBLEM TO BE SOLVED: To realize the single phase drive and simplify a structure by forming a toroidal coil as the stator winding of the stator. SOLUTION: This actuator has a structure where a moving body (6) is provided to move freely between the first and second stators (2, 3) having the stator coil (2a, 3a) of the toroidal coil and the moving body (6) can reciprocally move with a single phase drive current.
