置検出装置。[Claims for Utility Model Registration] A pair of magnets magnetized on opposing surfaces are opposed to each other with opposite polarities, a magnetically sensitive element is loosely inserted between the pair of magnets, and an actuator is provided, By displacing the actuator by following the moving body whose position is to be detected, the relative position of the pair of magnets and the magnetically sensitive element with respect to the magnetization direction is changed, and the magnetically sensitive element is moved according to the relative position. What is claimed is: 1. A position detection device for detecting the position of the movable body based on an output level of the moving object, the device comprising: means for adjusting the relative position; and means for adjusting the output level.
