PURPOSE: A backlash control device for a worm driver capable of changing the position of a wheel axle is provided to minimize the variation of the wheel axle in position. CONSTITUTION: A worm driver includes a worm(22) rotatably coupled to a driving shaft(21), and a worm wheel(24) installed in a body(10). The worm wheel is coupled to the worm and a driven shaft(23), and transmits the driving force of the worm to the drive shaft. A control housing(30) is rotatably coupled to the inside of the body. The driven shaft is coupled to the control housing eccentrically.
