Abstract
The seat position sensor includes a housing, a magnetoelectric converting element which performs changeover of an output at a given magnetic field intensity, and a magnet which is held by the housing at a position where the magnet faces the magnetoelectric converting element in an opposed manner. A shielding plate is capable of entering into or exiting from a space defined between the magnetoelectric converting element and the magnet. An inverse bias magnet which applies a magnetic field of an inverse direction to the magnet is provided to a side opposite to the magnet side while sandwiching the magnetoelectric converting element therebetween.
