PROBLEM TO BE SOLVED: To provide a vehicular steering device capable of suppressing rotation of a steering member when a turning angle of a turning wheel reaches a turning angle limit value.SOLUTION: A vehicular steering device includes: an input shaft connected to a steering wheel; a torsion bar which has one end connected to the input shaft; an output shaft connected to the other end of the torsion bar; a reaction force motor 19 which is connected to the output shaft and applies reaction force to the steering member; and a reaction force motor control section 70 for controlling the reaction force motor. The reaction force motor control section 70 includes target rotation angle setting means 71 which sets a target rotation angle of the output shaft at a position closer to a neutral position side of the output shaft by a rotation angle according to steering torque detected by a torque sensor 16 with respect to a rotation angle of the output shaft corresponding to a turning angle limit value when a turning angle of a turning wheel reaches the turning angle limit value and steering torque larger than steering torque at a point of time when the turning angle reaches the turning angle limit value is applied to the steering wheel.SELECTED DRAWING: Figure 5

    【課題】転舵輪の転舵角が転舵角限界値に到達しているときに、操舵部材が回転するのを抑制できる車両用操舵装置を提供する。【解決手段】ステアリングホイールに連結される入力軸と、入力軸に一端が連結されるトーションバーと、トーションバーの他端に連結される出力軸と、出力軸に連結され、操舵部材に反力を与えるための反力モータ19と、反力モータを制御する反力モータ制御部70とを含む。反力モータ制御部70は、転舵輪の転舵角が転舵角限界値に到達しており、かつ転舵角限界値への到達時点の操舵トルクよりもステアリングホイールに大きな操舵トルクが加えられているときには、転舵角限界値に対応する出力軸の回転角に対して、トルクセンサ16によって検出される操舵トルクに応じた回転角だけ、出力軸の中立位置側に近い位置に、出力軸の目標回転角を設定する目標回転角設定手段71を含む。【選択図】図5
