Abstract
A rotation angle detector is simple in structure and is capable of angle detection with a high resolution. First and second detecting units detect rotations of first and second detecting members rotating in association with a rotating member as detection signals in which predetermined waveforms continue. A control unit connected with the first and second detecting units detects a difference between the waveforms output from first and second detecting units as a gradually increasing detection signal and detects a rotation angle of the rotating member from two signals: the gradually increasing detection signal and the waveform output from the first detecting unit.
