Abstract
A steering-feel control device in a steer-by-wire system may include a pressure member for rotating in a predetermined direction or an opposite direction within a rotation path depending on the rotation direction of a steering wheel, a push block rotatably provided in the rotation path of the given or opposite direction, a first elastic member for providing elastic restoration force in the rotation direction of the pressure member for elastic variation in the rotational displacement between the pressure member and the push block, and a second elastic member for providing elastic restoration force in the rotation direction of the push block for elastic variation in the rotational displacement when the push block is rotated away from the pressure member, the second elastic member having an elastic constant smaller than that of the first elastic member and being provided in a pre-compressed state to have elastic force greater than that of the first elastic member.
