<p>PROBLEM TO BE SOLVED: To provide a stroke sensor capable of improving productivity.SOLUTION: Provided is a stroke sensor 1 for detecting, by a magnetic detection element 9a, the movement amount of a magnet 4 provided on a shaft 3 moving along with the movement of an object to be detected, wherein the stroke sensor is characterized in that the magnet 4 is provided with yokes 4, 40, 40a in adjacency along the axial direction of the shaft 3. Therefore, it is possible to make the magnet 4 sharable by disposing the yokes 4, 40, 40a adjacent to the magnet 4 instead of adjusting the thickness of the magnet 4 in accordance with the stroke amount of the shaft 3, making it possible to provide the magnet 4 at low cost. The stroke sensor capable of improving productivity can thereby be provided.</p> |
