Disclosed is a steering reaction force control device of a steer-by-wire system, including: a presser being rotated in one or the other direction within a rotational path set in accordance with the rotational direction of a steering wheel; a pressure block rotationally provided on rotational paths of the presser in one and the other directions; a first spring for providing an elastic restoring force with respect to a rotational direction of the presser so that the rotational displacement between the presser and the pressure block can be changed; and a second spring for providing an elastic restoring force with respect to the rotational direction of the pressure block such that the rotational displacement can be elastically changed as the pressure block is rotated in the direction away from the pressure, wherein the second spring has a smaller spring constant than the first spring and is configured to have a spring force greater than that of the first spring in a compressed state in advance at a steering angle neutral position.

    본 발명은 스티어링휠의 회전방향에 따라 설정된 회전경로 내에서 일방 또는 타방으로 회전되는 프레셔; 상기 프레셔의 일방 및 타방의 회전경로 상에 회전 가능하게 구비된 가압블록; 상기 프레셔와 가압블록 사이의 회전변위가 변화되도록 프레셔의 회전방향에 대해 탄성복원력을 제공하는 제1스프링; 및 상기 가압블록이 프레셔와 멀어지는 방향으로 회전됨에 따른 회전변위가 탄력적으로 변화되도록 가압블록의 회전방향에 대해 탄성복원력을 제공하고, 상기 제1스프링보다 작은 스프링상수를 갖되, 조향각 중립위치에서 미리 압축상태로 구비되어 상기 제1스프링보다 큰 스프링력을 갖도록 구성된 제2스프링;을 포함하여 구성되는 스티어 바이 와이어 시스템의 조향 반력장치가 소개된다.
