According to the present invention, a speed reducer for a motor driven power steering system is disclosed. The disclosed speed reducer for a motor driven power steering system comprises: a drive pulley coupled to a drive unit to be rotated; a driven pulley connected to the drive pulley with a belt as a medium; a ball nut unit coupled to the driven pulley, and moving a rack bar straight by converting the rotational force of the driven pulley; and a bearing unit interposed between the ball nut unit and a housing unit, rotationally supporting the ball nut unit, and coupling the ball nut unit to the housing unit to be tilted. Provided is the speed reducer for a motor driven power steering system, which supports the rack bar to be tilted, and applies the bearing unit which is detachably coupled to the housing unit, thereby reducing the number of components and noise.
