According to the present embodiments, provided is a rack-driven power assisted steering device in which a rolling member supporting the rotation of a ball nut is provided in a double row, a ball nut assembly is coupled to a housing through an elastic member, the flow of the ball nut is absorbed to improve noise performance, and the rolling member is directly supported by the ball nut or a support member, so that the number of parts can be reduced and easy assembly is possible.

    根据本实施例,提供了一种齿条驱动型动力辅助转向装置,该装置中支撑滚珠螺母的旋转的滚动构件设置成双排并且滚珠螺母组件通过弹性构件联接到壳体,通过吸收滚珠螺母的移动来改善噪音性能,并且滚动构件由滚珠螺母或支撑构件直接支撑,从而可以减少部件的数量并且可易于组装。
