To suppress power consumption to suppress a temperature rise, and to make a device compact.SOLUTION: A steer-by-wire system vehicular steering device is provided with a steering sensor 60 on an end portion on the opposite side to a steering wheel 1 side of a shaft 4. An operation converting mechanism 28 energizes an electromagnet 27 when an orientation of a steering wheel 3 reaches a stroke end, thereby circumferentially moving an engaging piece 24 from an engagement releasing state position to an engagement state position to lock an inner ring 20 connected to a shaft 4 and a fixed outer ring 21, and releases the energization to the electromagnet 27 when separating from the stroke end, thereby circumferentially moving the engagement piece 24 from the engagement state position to the engagement releasing state position to release the locking of the inner ring 20 and the outer ring 21.SELECTED DRAWING: Figure 2
【課題】電力の消費量を抑えて温度上昇を抑制し、装置をコンパクトにする。【解決手段】操舵センサ60をシャフト4のステアリングホイール1側とは反対側の端部に設け、動作変換機構28は、転舵輪3の向きがストロークエンドに到達したときに電磁石27に通電させて、係合子24を係合解除状態の位置から係合状態の位置に周方向移動させシャフト4に接続された内輪20と固定の外輪21とをロックし、ストロークエンドから離脱すれば電磁石27への通電を解除させて、係合子24を係合状態の位置から係合解除状態の位置に周方向移動させ内輪20と外輪21とのロックを解除するステアバイワイヤ方式の車両用操舵装置とした。【選択図】図2
