PURPOSE: A decelerator of an electric power auxiliary steering device is provided to prevent a motor from being malfunctioned due to an overload by assisting the control power of a steering wheel while individually rotating a first worm shaft and a second worm shaft in a normal direction or a reverse direction with a first motor and a second motor. CONSTITUTION: A decelerator of an electric power auxiliary steering device comprises a steering shaft (301), a worm wheel (303), a first worm shaft (310), and a second worm shaft (320). The steering shaft transmits rotatory power of a steering wheel. The worm wheel rotates by being connected to the steering shaft and includes a gear tooth (303a) on the outer circumference. The first worm shaft includes a first worm gear tooth (310a) connected to one side of the worm wheel and is driven by a first motor (315). The second worm shaft includes a second worm gear tooth (320a) connected to the other side of the worm wheel and is driven by a second motor (325). |
