PURPOSE:To easily perform the automatically corrected steering against disturbances such as the cross wind by changing the steering gear ratio in a wide range in response to the running mode such as the vehicle speed. CONSTITUTION:One end of a connecting rod 11 is connected to one end of the first rack shaft 5, the other end is connected to one end of the second rack shaft 9, and a portion near the hinge type joint 11' of the connecting rod 11 is connected to the front wheel 15. An electric motor 7 is controlled by the output signal of a control circuit 19 based on signals of a steering angle sensor 16, a vehicle speed sensor 17, and a lateral acceleration sensor 18. The rotation of the electric motor 7 is feedback-controlled by the output signal of the control circuit 19 and the output signal of an output angle sensor 20 detecting the rotation angle of the pinion 8 of the second gear box 10 and generating the output angle signal.
