Magnetic displacement detector

摘要

A magnet (5) is provided on a detection member (4) that moves on a straight line. A Hall element (6) serving as a magneto-electric element is provided on a fixed member (7) that opposes the magnet. A surface of the magnet that opposes the Hall element is formed into a radius or trapezoidal shape. With this arrangement, linear outputs can be obtained at any rotational angles even when a rotator rotates a plurality of times. <IMAGE>
