The present invention comprises: a worm shaft rotated by being engaged to a worm wheel gear fixed to the outer side of a steering shaft; a bearing member coupled to the worm shaft and reducing friction generated in rotation; and a noise reducing member provided to be in contact with the bearing member, and formed in a plurality of elastic spring structures such that a load applied to the bearing member can be varied.

    본 발명은 스티어링축의 외측에 고정되는 웜휠기어에 맞물려 돌아가는 웜샤프트와 상기 웜샤프트에 결합되어 회전 시 발생하는 마찰을 감소시키는 베어링부재 및 상기 베어링부재와 접하도록 구비되며, 상기 베어링부재로 작용하는 하중이 가변되도록 복수의 탄성 스프링 구조로 형성되는 소음저감 부재를 포함한다.
