전동식 조향장치에 관한 발명이 개시된다. 개시된 전동식 조향장치는, 동력을 발생시키는 구동부와, 웜기어가 구비되어 웜휠과 맞물려 회전하는 웜샤프트부와, 구동부와 웜샤프트부 사이에 위치하여, 구동부에서 발생된 동력을 웜샤프트부로 전달하는 커플링부를 포함하며, 커플링부는, 구동부의 회전축에 결합되는 제1커플러와, 웜샤프트부에 결합되고 제1커플러에 삽입되며, 제1커플러가 설정 각도 이상 회전되면 제1커플러에 접하는 제2커플러와, 제2커플러에 결합되며, 신축 가능하게 구비되고, 제1커플러에 접하여, 제2커플러의 이동을 제한하는 회전제한부를 포함하는 것을 특징으로 한다.

    The present invention provides a motor driven power steering system. The motor driven power steering system comprises: a drive unit generating power; a worm shaft unit provided with a worm gear to rotate by being engaged with a worm wheel; and a coupling unit placed between the drive unit and the worm shaft unit to transmit power generated in the drive unit to the worm shaft unit. The coupling unit comprises: a first coupler coupled to a rotating shaft of the drive unit; a second coupler coupled to the worm shaft unit, inserted into the first coupler, and coming in contact with the first coupler when the first coupler rotates more than a predetermined angle; and a rotation restriction unit coupled to the second coupler, provided to be flexible, and coming in contact with the first coupler to restrict movement of the second coupler.
