To provide a steer-by-wire system vehicle steering device that can restrict the rotation of a steering wheel at an arbitrary angular position.SOLUTION: In a steer-by-wire system including: a motor shaft 20 rotationally supported about an axis line different from a rotation axis line of a steering shaft 4; and a power transmission mechanism 6 connecting the motor shaft 20 and the steering shaft 4 so as to transmit torque, an electromagnetic brake 7 is disposed coaxially with the motor shaft 20, the electromagnetic brake being configured to switch between a rotation allowable state where the rotation of the motor shaft 20 is allowed by switching energization and non-energization and a rotation restricted state where the rotation of the motor shaft 20 is restricted.SELECTED DRAWING: Figure 2

    【課題】ステアリングホイールの回転を任意の角度位置で規制することが可能なステアバイワイヤ方式の乗り物用操舵装置を提供する。【解決手段】ステアリングシャフト4の回転軸線と食い違う軸線まわりに回転可能に支持されるモータ軸20と、モータ軸20とステアリングシャフト4をトルク伝達可能に連結する動力伝達機構6とを有するステアバイワイヤ方式の乗り物用操舵装置において、通電と非通電の切り替えによりモータ軸20の回転を許容する回転許容状態とモータ軸20の回転を阻止する回転制動状態とを切り替える電磁ブレーキ7をモータ軸20と同軸上に設けた。【選択図】図2
