PROBLEM TO BE SOLVED: To suppress occurrence of a situation where a vehicle height is made lower than an originally set vehicle height due to a failure of a vehicle height detecting portion.SOLUTION: A vehicle height adjustment device comprises: a changing device that changes a relative position between a vehicle main body and an axle of a vehicle; a detecting portion that detects the relative position between the vehicle main body and the axle; a vehicle height control device that controls a height of the vehicle main body, or a vehicle height, by controlling the changing device on the basis of detected value by the detecting portion to change the relative position; and a failure detecting portion that detects whether a failure may occur in the detecting portion if the detected value by the detecting portion varies by a predetermined amount or more during a predetermined period of time.SELECTED DRAWING: Figure 14

    【課題】車高の検出部の故障によって本来の設定よりも車高を低下させてしまう事態の発生を抑制する。【解決手段】車高調整装置は、車両の車両本体と車軸との相対位置を変更する変更装置と、車両本体と車軸との相対位置を検出する検出部と、この検出部の検出値に基づき変更装置を制御して相対位置を変更することにより、車両本体の高さである車高を制御する車高制御装置と、検出部による検出値が、所定期間内に所定量以上変動した場合に、検出部に故障が発生した可能性があることを検出する故障検出部と、を備える。【選択図】図14
