Abstract
A movable member coupled to a displacement detector via a void is disposed with respect to a fixed member to which a coil is fixed. By disposing the coil in a closed loop magnetic circuit including a permanent magnet, the movable-side member, and the fixed member, a Lorentz force for moving the movable-side member in the axial direction is generated.
