The present invention relates to an electric power steering apparatus for a vehicle. An interval due to a backlash between a worm wheel (200) and a worm shaft (300) and flow of the worm shaft (300) are prevented by using a bearing-integrated damper bush (600) made of steel coupled to an end part of the worm shaft (300). When the worm shaft (300) rotates, a lubricant (800) is supplied between the worm shaft (300) and the bearing-integrated damper bush (600) to promote lubrication and cooling. The electric power steering apparatus for the vehicle of the present invention comprises: the worm shaft; and a the bearing-integrated damper bush.

    본 발명은 차량용 전동식 조향장치에 관한 것으로, 웜샤프트(300)의 단부에 결합되는 스틸재질의 베어링 통합형 댐퍼부시(600)를 이용해서 웜휠(200)과 웜샤프트(300)의 백래쉬에 의한 유격방지 및 웜샤프트(300)의 유동을 방지하고, 웜샤프트(300)의 회전시 웜샤프트(300)와 베어링 통합형 댐퍼부시(600)사이로 윤활제(800)를 공급하여 윤활 및 냉각을 촉진할 수 있도록 된 것이다.
