The present invention relates to a rack driving type power assist steering device. The rack driving type power assist steering device comprises: a screw groove unit enabling a rack bar to be slid inside a rack housing and having the inner circumferential screw groove where the rack bar is coupled to the inner circumferential surface by a means of a ball; a ball nut extended from the screw groove unit in the shaft direction to have a cylindrical unit where a nut pulley is coupled to the outer circumferential surface; and a bearing coupled to the inside of the screw groove unit among the outer circumferential surface of the ball nut to support a gap between the rack housing and the ball nut. Therefore, the present invention reduces a difference of noises which are generated while a driver steers the vehicle leftward and rightward.

    본 발명은 랙구동형 동력 보조 조향장치에 관한 것으로, 랙하우징 내측에서 랙바를 슬라이딩시키고, 내주면에 랙바가 볼을 매개로 결합되는 내주스크류홈이 형성된 스크류홈부와, 스크류홈부에서 축방향으로 연장되어 외주면에 너트풀리가 결합되는 원통부가 구비되어 있는 볼너트 및 볼너트의 외주면 중 스크류홈부 내에 결합되어 랙하우징과 볼너트 사이를 지지하는 베어링을 포함하여 운전자의 좌측과 우측으로 조향시 발생되는 노이즈의 차이를 줄인다.
