The present invention relates to a steer-by-wire steering device comprising: a slide bar that slides in an axial direction by a motor; a housing that accommodates the slide bar; and a damper formed in a ring shape and including a first support portion coupled to an inner circumferential surface of the housing and supported by the inner circumferential surface of the housing in a circumferential direction, and a second support portion coupled to the slide bar and supported by the slide bar in the circumferential direction. According to the embodiment, the number of parts is reduced by removing parts such as a pinion and a support yoke, and the shape and assembly process of the parts are simplified, so that the cost is reduced, the operation noise caused by friction between gears and the noise caused by reverse steering are reduced, the noise performance is improved, the friction during driving is reduced, and the durability of the parts is improved.

    本发明涉及一种线控转向型转向装置,其包括:滑动杆,通过马达沿轴向滑动;壳体,容纳上述滑动杆;以及阻尼器,形成为环状,并且包括结合到所述壳体的内周面并在圆周方向上被所述壳体的内周面支撑的第一支撑部和结合到所述滑动杆并在圆周方向被所述滑动杆支撑的第二支撑部。根据本实施例,通过去除小齿轮和支撑轭等部件而减少部件数量,简化部件的形状和组装工艺,从而降低成本,降低齿轮之间的摩擦引起的操作噪音和反向转向引起的噪音以改善噪音性能,减少驱动时的摩擦,提高部件的耐久性。
