PROBLEM TO BE SOLVED: To provide an electric power steering system which electrically generates steering auxiliary force when a driver steers with an inexpensive cost and a simple constitution compared with a hydraulic power steering system. SOLUTION: The electric power steering system comprises an input shaft connected to a steering handle, an output shaft connected to a steering wheel, a motor installed so as to transmit auxiliary steering force to the output shaft, a torsion bar to connect the input shaft to the output shaft and to generate torsional displacement when steering, a switch board and a resistance board mutually exclusively mounted on the input shaft and the output shaft individually and structured such that the resistance to electricity passing through is varied depending on the torsional displacement of the torsion bar, an input means for continuously supplying electricity to the switch board rotating, and an output means for outputting electricity which is passed through the resistance board rotating.
