The present invention relates to a steering actuator device for a vehicle, which comprises: a housing; a driving unit supported by the housing and generating driving force; a transmission shaft unit installed to be movable inside the housing and varying an angle of a wheel while receiving the driving force from the driving unit to reciprocate; a measurement unit linked to movement of the transmission shaft unit to measure a steering angle of the wheel; and a rotation prevention unit provided between the housing and the transmission shaft unit to prevent relative rotation of the transmission shaft unit and the housing. According to the present invention, the steering actuator device for a vehicle has a simplified coupling structure of a steering angle sensor and can stably support a rack bar.

    본 발명은 차량용 조향 액추에이터 장치에 관한 것으로, 하우징과, 하우징에 의해 지지되고, 구동력을 발생시키는 구동부와, 하우징 내부에 이동 가능하게 설치되고, 구동부로부터 구동력을 전달받아 왕복 이동하며 휠의 각도를 가변시키는 전달축부와, 전달축부의 이동에 연동되어 휠의 조향각을 측정하는 측정부 및 하우징과 전달축부의 상대 회전이 방지되도록 하우징과 전달축부의 사이에 구비되는 회전방지부를 포함하는 것을 특징으로 한다.
