In a position detecting device including a movable member provided in a displaceable manner on a base member, and a proximity sensor which detects the position of the movable member, the proximity sensor includes a magnetic field generating portion, a detecting portion which detects a change in magnetic field according to the displacement of the movable member, and a protruding portion made of a nonmagnetic material, which protrudes toward an object to be detected. A seat position detecting device of a vehicle including the configuration of the position detecting device mentioned above is provided. The base member is comprised of a lower rail which is fixedly installed on a floor of a vehicle body, and the movable member is comprised of an upper rail which is attached to a seat for a vehicle and slidably engaged with the lower rail and which is allowed to be fixed in arbitrary sliding positions on the lower rail.
