According to embodiments, provided is a rack-driven type power assisted steering device, wherein rolling members supporting the rotation of a ball nut are provided in a double row, and a ball nut assembly is coupled to a housing through an elastic member. Moreover, the movement of the ball nut is absorbed to improve noise performance, and the rolling members are directly supported by the ball nut or the support member. Therefore, the rack-driven type power assisted steering device can be easily assembled with reduced number of parts.

    본 실시예들에 의하면, 볼너트의 회전을 지지하는 구름부재가 복열로 구비되고 볼너트조립체가 하우징에 탄성부재를 매개로 결합되며 볼너트의 유동이 흡수되어 노이즈 성능이 개선되고, 구름부재가 볼너트 또는 지지부재에 직접 지지되어 부품 수가 감소되고 용이하게 조립이 가능한 랙구동형 동력 보조 조향장치가 제공될 수 있다.
