Abstract
To improve the detection accuracy of a rotation angle of a rotation shaft caused by the magnetic flux distribution of a magnet. In an absolute encoder, a support shaft has one end fixed to a gear base part as a substrate, and includes a flange part at the other end. A first bearing and a second bearing as at least one bearing include inner rings fixed to the support shaft. The first bearing and the second bearing are disposed between the gear base part and the flange part in an axial direction. A spacer is disposed between the first bearing and the second bearing, and a magnet (Mq), in the axial direction of the support shaft. The spacer is in contact with outer rings of the first bearing and the second bearing from the axial direction inside a bearing fixing part.
