PROBLEM TO BE SOLVED: To provide a rear wheel steering device which can find an abnormality of a rod position detector for detecting a position of a rod in an axial direction before the traveling of a vehicle.SOLUTION: When a power supply is powered on, a position of a second rod 16 detected by a second rod position detector 51 is stored as an initial position P. After that, the second rod 16 is slightly moved by a prescribed command value C. After that, a difference ΔPbetween the position Pof the second rod 16 detected by the second rod position detector 51 and the initial position Pof the second rod 16 is calculated. The difference ΔPis compared with the command value C, and when both the difference and the value do not coincide with each other, an abnormality is determined.SELECTED DRAWING: Figure 2

    【課題】ロッドの軸方向の位置を検出するロッド位置検出器の異常を、車両走行前に発見することが可能な後輪転舵装置を提供する。【解決手段】電源が投入されたときに、第2のロッド位置検出器51で検出される第2のロッド16の位置を初期位置P0として記憶する。その後、第2のロッド16を所定の指令値Cだけ軸方向に微小移動させる。その後、第2のロッド位置検出器51で検出される第2のロッド16の位置P1と、第2のロッド16の初期位置P0との差分ΔP1を算出する。その差分ΔP1と指令値Cとを比較し、両者が一致しないときは異常と判定する。【選択図】図2
