Abstract: A magnetic sensor is able to detect a magnetic field applied from a position detecting magnet that makes relative movement as an optical reflector is rotated. Rotation of the optical reflector enables the position detecting magnet to pass through a reference position where a rotation axis, a center or approximate center of the magnetic sensor, and a center or approximate center of the position detecting magnet are located in order on a straight line, as seen in the axial direction of the rotation axis. The magnetic sensor is in an XZ plane that includes a magnetization direction passing through the center or approximate center of the position detecting magnet located at the reference position, and the axial direction of the rotation axis.
