According to embodiments, a rack bar support apparatus for a vehicle steering apparatus comprises: a rack bar engaged with a pinion shaft; a guide member provided in a housing and having a first inclined surface facing the rear surface of the rack bar; a rack bar support member having a yoke portion supported on the rear surface of the rack bar and a second inclined surface in contact with the first inclined surface; and an elastic member which is supported, in an axial direction, between the guide member and the rack bar support member, and bringing the rack bar support member into close contact with the rack bar. Clearance caused by the wear of the rack bar support member is compensated to achieve engagement between the pinion shaft and the rack bar, an increase in the clearance is prevented to reduce noise, assembly convenience is increased by simplifying a structure so that the rack bar support apparatus can be assembled in an axial direction of the rack bar, and a space occupied in the vehicle can be minimized.

    본 실시예들에 의한 자동차의 조향장치의 랙바 지지장치는, 피니언축과 치합되는 랙바, 하우징에 구비되되 랙바의 배면과 대향되는 제 1 경사면이 구비되는 가이드부재, 랙바의 배면에 지지되는 요크부와 제 1 경사면에 접하는 제 2 경사면이 구비되는 랙바지지부재, 가이드부재와 랙바지지부재 사이에서 축방향으로 지지되어, 랙바지지부재를 랙바에 밀착시키는 탄성부재를 포함하여, 랙바지지부재의 마모로 발생되는 유격을 보상함으로써 랙바와 피니언축의 치합이 잘 이루어지게 하고, 유격이 증대되는 것을 방지하여 노이즈를 감소시키고, 랙바의 축방향으로 조립할 수 있도록 구조를 단순화시켜 조립편의성이 향상되고 차량 내에서 차지하는 공간을 최소화시킬 수 있는 것을 목적으로 한다.
