PROBLEM TO BE SOLVED: To apply an appropriate steering reaction force corresponding to a driving condition to a steering shaft while ensuring an excellent steering feeling when a steering operation is performed in a steer-by-wire system.SOLUTION: A vehicular steering device comprises: a steering shaft 11 rotatable around an axis by a steering operation; a turning shaft 12 rotating around an axis for driving a steering device 3 that steers a wheel 2 to the left and right; an elastic member 20 interposed between the steering shaft 11 and the turning shaft 12 and applying a steering reaction force to the steering shaft 11 according to relative rotation of both shafts 11, 12 about the axes; and a clutch 10 capable of switching between a direct connection state in which the relative rotation around the axes between the steering shaft 11 and the turning shaft 12 during the steering operation is disabled and a disconnection state in which the relative rotation is permitted.SELECTED DRAWING: Figure 2

    【課題】ステアバイワイヤ方式において転舵操作を行う際に、良好な操舵感覚を確保しつつ、操舵軸に運転状況に対応した適切な操舵反力を与えること。【解決手段】ステアリング操作によって軸周りに回転可能な操舵軸11と、軸周りに回転して、車輪2を左右に転舵する転舵装置3を駆動する転舵軸12と、操舵軸11と転舵軸12との間に介在して設けられ、両軸11、12の軸周りの相対回転に伴って操舵軸11に操舵反力を与える弾性部材20と、ステアリング操作時における操舵軸11と転舵軸12との間の軸周りの相対回転を不能とする直結状態、又は、前記相対回転を許容する切り離し状態のいずれかの状態に切り替え自在とするクラッチ10と、を備えた車両用操舵装置を構成する。【選択図】図2
