The present invention relates to a rack type power steering apparatus, including: a ball nut, which has a rack bar coupled to the inner circumferential surface thereof, is divided into a first ball nut and a second ball nut rotating together by being screw-coupled to each other, and has a first coupling portion formed in a cylindrical shape by protruding axially from one side end at any one of the first ball nut and the second ball nut, and a second coupling portion formed at the other of the first ball nut and the second ball nut so as to have a reduced diameter on the outer circumferential surface and screw-coupled to the first coupling portion; and a bearing which is coupled to the inner side of a rack housing so as to support rotation of the first ball nut and the second ball nut, and has one side of an inner race supported by a lock nut coupled to the outer circumferential surface of the second ball nut, and the other side of the inner race supporting a sill member with coupling power of the lock nut.

    본 발명은 랙구동형 동력 보조 조향장치에 관한 것으로, 내주면에 랙바가 결합되고, 서로 나사결합되어 함께 회전되는 제1볼너트와 제2볼너트로 분리되되, 제1볼너트와 제2볼너트 중 어느 하나에는 일측단에서 축방향으로 돌출되어 원통형으로 형성되는 제1결합부가 구비되고 나머지 하나에는 외주면에서 직경이 축소되어 형성되어 제1결합부에 나사결합되는 제2결합부가 구비되어 있고, 제1볼너트의 외주면에 링형상의 단턱부재가 결합되는 볼너트, 랙하우징 내측에 결합되어 제1볼너트와 제2볼너트의 회전을 지지하며, 내륜의 일측은 제2볼너트 외주면에 체결되는 락너트에 지지되고 내륜의 타측은 락너트의 체결력으로 단턱부재를 지지하는 베어링을 포함한다.
