본 실시예들에 의한 전동식 동력 보조 조향장치는, 일측면이 개구되어 웜휠이 수용되는 제 1 수용부, 제 1 수용부와 연통되고 웜축이 수용되는 제 2 수용부가 구비되는 하우징, 제 1 수용부의 일측면에 결합되는 하우징커버, 하우징과 하우징커버에 경방향으로 축력을 제공하는 결합부재를 포함하여, 웜축과 맞물리는 웜휠을 수용하는 하우징과 하우징커버가 축방향 및 경방향으로 지지됨으로써 웜휠에 발생하는 하중에 의해 하우징과 하우징커버가 분리되거나 어긋나는 것을 방지할 수 있으며, 하우징과 하우징커버를 결합하는 볼트 등이 적은 개수 또는 작은 직경으로 구비되더라도 축방향 및 경방향 하중을 모두 지지할 수 있어 원가가 절감되고 조립공정이 단순화될 수 있다.

    According to embodiments of the present invention, an electric power assisted steering apparatus comprises: a housing having a first receiving portion in which one side is opened to accommodate a worm wheel, a second receiving portion communicating with the first receiving portion and receiving a worm axis; a housing cover coupled to one side of the first receiving portion; and a coupling member which provides an axial force to the housing and the housing cover in the radial direction. Accordingly, the housing accommodating the worm wheel meshing with the worm axis, and the housing cover are supported in the axial and radial directions, so that the housing and housing cover can be prevented from being separated or shifted by the load generated on the worm wheel. Even if the number of bolts connecting the housing and housing cover are provided with a small number or small diameter, both axial and radial loads can be supported, thereby reducing cost and simplifying the assembly process.
