The present invention relates to a rack assist type power steering apparatus. According to the present invention, in the rack assist type power steering apparatus, the weight of a nut pulley can be greatly reduced, and noise due to friction with a belt also can be greatly reduced. In addition, in comparison with an existing one in which a ball nut and the nut pulley are coupled by indenting, the rack assist type power steering apparatus can greatly increase coupling force of the ball nut and the nut pulley and can prevent a condition that the nut pulley runs idle so that steering assist force is changed or steering is unable during high speed running. Therefore, a stable steering condition can be provided to a driver.

    본 발명은 랙구동형 동력 보조 조향장치에 관한 것으로 본 발명에 의하면, 랙구동형 동력 보조 조향장치에 있어서 너트풀리의 중량을 대폭 감소시키면서 벨트와의 마찰에 의한 노이즈를 대폭 감소시키는 효과가 있게 된다. 또한, 종래에 볼너트와 너트풀리가 압입에 의해 결합되는 것에 비하여 볼너트와 너트풀리의 결합력이 대폭 증대되고 너트풀리가 헛돌면서 조향 보조력이 변동되거나 고속 주행중 조향 불능 상태를 미연에 방지하여 운전자에게 안정된 조향 조건을 제공하는 효과를 갖게 된다.
