To provide a single wheel independent steering device having high practicability.SOLUTION: A steering device includes an electric motor 36a as a driving source, an operation conversion mechanism 44 for converting operation of the electric motor into steering operation of a wheel, and a controller 50 for achieving steering of the wheel 12 according to the operation position of the electric motor by controlling supply current to the electric motor, and detects deviation between the operation position of the electric motor and the steering position of the wheel based on supply current to the electric motor when the operation position of the electric motor is kept at a direct advance state position, and executes reference change processing of changing setting of the direct advance state position so as to dissolve the detected deviation. The deviation between the steering position of the wheel and the operation position of the electric motor can be easily dissolved by execution of the reference change processing.SELECTED DRAWING: Figure 1
【課題】 実用性の高い単輪独立転舵装置を提供する。【解決手段】 駆動源としての電動モータ36aと、その電動モータの動作を車輪の転舵動作に変換する動作変換機構44と、その電動モータへの供給電流を制御することでその電動モータの動作位置に応じた車輪12の転舵を実現させるコントローラ50とを備えた単輪独立転舵装置において、電動モータの動作位置が直進状態位置に維持されているときの電動モータへの供給電流に基づいて、電動モータの動作位置と車輪の転舵位置とのズレを検出し、その検出されたズレを解消すべく、直進状態位置の設定を変更する基準変更処理を実行する。その基準変更処理の実行によって、車輪の転舵位置と電動モータの動作位置とのズレを、容易に解消することができる。【選択図】 図1
