ABSTRACT:
An actuator has a cylindrical body, on the outer peripheral surface of which an induction coil is formed directly and a piston accommodated in the body and functioning as a core. The displacement of the piston can be detected by a detecting circuit for the change of the coil inductance in response to the displacement of the piston.
