Abstract
PURPOSE:To surely detect the moving portion of an ultra short stroke in the title apparatus by enclosing a plurality of detecting elements in a state of being shifted from each other in the moving direction of an actuator in one case. CONSTITUTION:A detecting element 3a on one side is attached on one side main surface of a substrate 2 and the detecting element 3b on the other side is attached on the opposite main surface of the substrate 2 and both detecting elements 3a, 3b are arranged in a state of being shifted from each other in the piston moving direction by exactly a distance equal to the length of the piston stroke. Through this manner, since the mutual distance between a plurality of detecting elements 3a, 3b in one case 7 can be selected appropriately as required, the moving portion of the ultra short stroke can be surely detected.
