ABSTRACT:
A position detecting sensor includes a magnet, a magnetic detecting element, and a yoke adjacent to or near the magnet. A detected member is positioned at one side of the position detecting sensor so as to be adjacent to or away from the position detecting sensor. The magnet is oriented to generate a magnetic line of flux which flows in a direction complying with an extending direction of the detected member. The magnetic detecting element is positioned in an area in which a magnetic flux density generated by the magnet is relatively low when the detected member is positioned away from the position detecting sensor and a magnetic flux density is relatively high when the detected member is positioned adjacent to the position detecting sensor.
