Abstract

A rotation angle detector for detecting a relative rotation angle of two respective parts includes two sensors, two magnetic flux induction devices as well as a magnetic flux generation unit. Variation in the magnetic flux formed in respective gaps of the two magnetic flux induction devices is detected by using the two magnetic sensors for detecting a relative rotation angle of the two parts.
