According to the characteristics of the present invention, a steering shaft fixed bearing structure is fixed to a vehicle body and is penetrated by a steering shaft, when the steering shaft formed at a lower part of a steering wheel of a vehicle is installed to penetrate the body of the vehicle. The steering shaft fixed bearing structure includes: a pair of bearings combined to the steering shaft; a pair of bearing housings which are combined to surround the outer circumference of the bearing, and have a concave groove part formed along the outer circumference; and a pair of seal parts which have a through-hole combined to the bearing housing, and have a protrusion which is formed on the inner circumference of the through-hole and is combined to the concave groove part formed on the outer circumference of the bearing housing. The concave groove part formed in the bearing housing is combined with the protrusion formed on the inner circumference of the through-hole of the seal part, so insertion of foreign substances into the seal part and corrosion thereof are prevented. According to the present invention seen in the above, provided is the steering shaft fixed bearing structure which can prevent corrosive substances and foreign substances or noise generated from an engine room from being inputted into the vehicle.

    본 발명의 특징에 따르면, 자동차의 스티어링 휠 하부에 구비되는 스티어링 샤프트가 차량의 차체를 관통하여 설치될 때, 상기 차체에 고정되며 상기 스티어링 샤프트가 관통되는 스티어링 샤프트 고정 베어링 구조에 있어서, 상기 스티어링 샤프트에 결합되는 한 쌍의 베어링; 상기 베어링의 외주면을 감싸도록 결합되며, 외주면을 따라 오목홈부가 형성된 한 쌍의 베어링하우징; 및 상기 베어링하우징과 결합되는 관통홀을 갖되, 상기 관통홀의 내주면에 돌기부가 형성되며, 상기 돌기부가 상기 베어링하우징의 외주면에 형성된 오목홈부와 결합된 한 쌍의 씰부;를 포함하고, 상기 베어링하우징에 형성된 오목홈부와 상기 씰부의 관통홀 내주면에 형성된 돌기부가 결합되며, 상기 씰부의 내부로 이물질의 투입 및 부식을 방지한다. 이상 살펴본 바와 같은 본 발명에 따르면, 엔진룸으로부터 발생되는 소음이나 이물질 및 부식물을 차량의 실내로 유입되는 것을 방지할 수 있는 방지할 수 있는 스티어링 샤프트 고정 베어링 구조를 제공할 수 있다.
