An electric power steering system (100) for vehicles includes a driving control circuit (50) adapted to generate a torque magnitude signal (Sa) and a torque direction signal (Sdr, Sdl), based on an output signal (VR, VL) from a torque detection mechanism (4, 9) for detecting the magnitude and the direction of steering torque acting on an input shaft (101) connected to a steering wheel (8), and to feed, to an electric motor (5) for supplying auxiliary torque to an output shaft (3) operatively interconnected with a steered ground wheel, an armature current (Io) of such a magnitude and in such a direction of conduction as desirous in accordance with both the torque magnitude signal (Sa) and the torque direction signal (Sdr, Sdl). The steering shaft (101) comprises a first shaft (1) connected to the steering wheel (8), a second shaft (2) interconnected with the first shaft (1), and a third shaft (3) as the output shaft (3) interconnected with the second shaft (2), and a torque detecting means ( 4, 9) comprising a torque direction detecting mechanism (4) interposed between the first shaft (1) and the second shaft (2), and a torque magnitude detecting mechanism (9) interposed between the second shaft (2) and the third shaft (3).
