According to one aspect of the present invention, provided is a reducer of an electronic power steering system, including: a gear housing including a worm housing and a worm wheel housing; a worm shaft which is disposed in the worm housing, rotates by receiving the rotational force of a driving unit, supports rotation by a first bearing coupled to one end close to the driving unit of both ends and a second bearing coupled to the other end thereof, and has a worm formed on the outer circumferential surface; a worm wheel which is disposed in the worm wheel housing and is engaged with the worm; and a clearance compensator for compensating for a clearance generated between the worm and the worm wheel by pressing the worm shaft in the direction of the worm wheel by coming in contact with one side of both sides of the first bearing, which is close to the driving unit.

    본 발명의 일 측면에 따르면, 웜 하우징 및 웜휠 하우징을 포함하는 기어 하우징; 상기 웜 하우징 내에 배치되고, 구동부의 회전력을 전달받아 회전하되, 양단부 중 상기 구동부와 가까운 일단부에 결합된 제1 베어링과 타단부에 결합된 제2 베어링에 의해 회전이 지지되며, 외주면에 웜이 형성되는 웜축; 상기 웜휠 하우징 내에 배치되며, 상기 웜과 치합되는 웜휠 및 상기 제1 베어링의 양측면 중 상기 구동부와 가까운 일측면에 접하여 상기 웜축을 상기 웜휠 방향으로 가압함으로써 상기 웜과 상기 웜휠 사이에 발생하는 유격을 보상하여 주는 유격보상기구를 포함하는 전동식 조향장치의 감속기가 제공된다.
