Abstract
A position sensor for a transmission mode selector lever includes a magnet and three magnetic flux detection elements that detect magnetic flux of the magnet. A determination circuit determines an operation position of the transmission mode selector lever based on output levels of detection signals generated by the magnetic flux detection elements. The magnet includes first and second magnetized regions. The first and second magnetized regions are formed so that when the magnet is moved relative to the magnetic flux detection elements along a straight line, output levels of the detection signals generated by the magnetic flux detection elements change in accordance with a proportional relationship having a first or second gradient relative to the distance of the movement. The three detection elements are spaced apart from each other on a straight line that is parallel to the first and second straight lines.
