In a magnet 2 which is relatively displaced with a magnetic sensor 3, parts 2A-N and 2B-S are magnetized in the opposite direction to the magnetic sensor 3 with O1 set as a magnetizing axis. Parts 2A-S and the 2B-N are magnetized in the opposite direction to the magnetic sensor 3 with O2 set as the magnetizing axis.
