The present embodiments relate to a steer-by-wire type steering apparatus. According to the present embodiments, provided is the steer-by-wire type steering apparatus, comprising: a ball nut having an inner circumferential screw groove provided on the inner circumferential surface thereof and having a ball circulation path for connecting one end and the other end of the inner circumferential screw groove between the inner circumferential surface and the outer circumferential surface thereof; a ball screw having an outer circumferential screw groove provided on the outer circumferential surface thereof to correspond to the inner circumferential screw groove and axially sliding by rotation of the ball nut by balls; a first shaft rotatably coupled to a steering column and having one end coupled to a steering wheel and the other end coupled so that one end of the ball screw is slid; a second shaft having one end coupled so that the other end of the ball screw is slid and the other end coupled to a reaction motor; and a rotation angle restriction member coupled to the ball nut and inserted into the ball circulation path to restrict the circulation of the balls. When the rotation of wheels reaches the maximum point or when the same can no longer be rotated, the steer-by-wire type steering apparatus prevents a steering shaft from being further rotated so that a driver can recognize this condition and take action.

    본 실시예들은 스티어 바이 와이어식 조향장치에 관한 것으로, 본 실시예들에 의하면, 내주면에 내주스크류홈이 구비되고 내주면과 외주면 사이에 내주스크류홈의 일측단과 타측단을 연결하는 볼순환로가 구비되어 있는 볼너트, 외주면에 내주스크류홈과 대응되는 외주스크류홈이 구비되고 볼을 매개로 볼너트의 회전에 의해 축방향으로 슬라이딩되는 볼스크류, 조향컬럼에 회전가능하게 결합되되, 일측단은 조향휠과 결합되고 타측단은 볼스크류의 일측단이 슬라이딩되도록 결합되는 제1축, 일측단은 볼스크류의 타측단이 슬라이딩되도록 결합되고 타측단은 반력모터와 결합되는 제2축, 볼너트에 결합되며 볼순환로의 내측으로 삽입되어 볼의 순환을 제한하는 회전각제한부재를 포함하는 스티어 바이 와이어식 조향장치가 제공될 수 있다.
