To achieve, in a steering system, downsizing of a displacement amount obtaining device that obtains the displacement amount of a steering shaft.SOLUTION: In the displacement amount obtaining device, a rotation angle of a rotating body that rotates around an axial line together with a displacement of a steering shaft in the axial-line direction is detected by a rotation angle detecting unit, and the displacement amount of the steering shaft is obtained on the basis of the rotation angle detected by the rotation angle detecting unit. As described above, the displacement amount obtaining device includes the rotation angle detecting unit that detects the rotation angle of the rotating body. Hence, in comparison with linear-type displacement amount obtaining devices that obtain the displacement amount of the steering shaft in the axial-line direction by utilizing an electromagnetic or optical change due to the displacement of the steering shaft in the axial-line direction, downsizing can be accomplished.SELECTED DRAWING: Figure 5
【課題】転舵システムにおいて、転舵軸の移動量を取得する移動量取得装置の小形化を図ることである。【解決手段】本移動量取得装置において、転舵軸の軸線方向の移動に伴って軸線回りに回転させられる回転体の回転角が回転角検出部によって検出され、その回転角検出部によって検出された回転角に基づいて転舵軸の移動量が取得される。このように、移動量取得装置は、回転体の回転角を検出する回転角検出部を含むものである。そのため、転舵軸の軸線方向の移動量を、転舵軸の軸線方向の移動に伴う電磁的または光学的な変化を利用して取得するリニア型の移動量取得装置に比較して、小形化を図ることができる。【選択図】 図5
