Disclosed is a motor driven steering device. The motor driven steering device comprises a worm wheel gear, a worm shaft, a bearing member, a base part and multiple elastic bodies. The worm wheel gear is fixed to the outside of a steering shaft. The worm shaft is engaged with the worm wheel gear to be rotated. The bearing member is installed to have a shape to cover the exterior of the worm shaft and reduce friction generated when the worm shaft is rotated. The base part is mounted on a housing member covering the worm shaft and the bearing member. The multiple elastic bodies are positioned in the inner space of the base part while the elastic bodies are in contact with the bearing member and are operated under each difference load. The motor driven steering device can reduce the number of parts thereof and simplify the assembly process.

    전동식 조향장치에 대한 발명이 개시된다. 본 발명의 전동식 조향장치는: 스티어링축의 외측에 고정되는 웜휠기어와, 웜휠기어에 맞물려 돌아가는 웜샤프트와, 웜샤프트의 외측을 감싸는 형상으로 설치되며 웜샤프트의 회전시 발생하는 마찰을 감소시키는 베어링부재와, 웜샤프트와 베어링부재를 감싸는 하우징부재에 장착되는 베이스부 및 베어링부재에 접한 상태에서 베이스부의 내측공간에 위치하며 서로 다른 작용하중에서 작동되는 복수 개의 탄성체를 포함하는 것을 특징으로 한다.
