摘要：
A rotation angle detector for detecting change in the magnetic flux has a magnetic sensor being disposed at a position in a space between an outer surface of a shaft and a periphery of the magnetic flux generation means. A supplementary magnet is also used in a space that is enclosed in a circular trace of the magnetic sensor around the shaft for even distribution of the magnetic flux generated by the magnetic flux generation means.
