Zusammenfassung:	To improve the detection accuracy of the magnetic field generated with the rotation of a rotary member.SOLUTION: A magnet 2 is bonded to a steering shaft 100. A magnetic yoke member 3 has a portion facing the magnet 2 in the direction crossing a rotation axis A of the steering shaft 100. A detection portion 4 detects a magnetic field, and outputs a signal corresponding to the detected magnetic field. A support body 5 supports the detection portion 4, and displaces following the displacement of at least the magnetic yoke member 3.SELECTED DRAWING: Figure 3 【課題】回転部材の回転に伴って生ずる磁場の検出精度を向上させる。【解決手段】磁石２は、ステアリングシャフト１００に結合される。磁気ヨーク部材３は、ステアリングシャフト１００の回転軸Ａと交差する方向に磁石２と対向する部分を有している。検出部４は、磁場を検出し、検出された磁場に応じた信号を出力する。支持体５は、検出部４を支持しており、少なくとも磁気ヨーク部材３の変位に追随して変位する。【選択図】図３
