    摘要： A device for detecting an absolute rotation angle of multiple rotation with a high accuracy and high resolution by using a target connected to the rotation axis and having an outer circumferential surface to which magnetic poles of alternate polarities are magnetized. The device includes: a first rotor holding a target connected to an input axis and having an outer circumferential surface to which magnetic poles of alternate polarities are magnetized at an identical interval and having a multi-rotatable gear; a second rotor connected to the gear of the first rotor, rotated at a low speed by the first rotor, and having a magnet at the center portion; a first detection unit and a second detection unit for detecting the rotation angles of them. With a simple configuration, it is possible to detect an absolution rotation angle with a high accuracy and a high resolution.
