Abstract
A rotation angle detecting device includes a magnetic member for providing a magnetic field, a magnetic sensor for sensing a change in the magnetic field when the magnetic member rotates relative to the magnetic sensor about a rotation axis. The magnetic sensor is disposed at a single position and includes a pair of sensor elements. The pair of sensor elements is disposed on an imaginary plane that is perpendicular to the rotation axis so that sensing surfaces of the sensor elements have 90 degrees in angle to each other and so that each of the sensing surfaces inclines by 45 degrees in angle to a line intersecting the rotation axis at right angles.
