PROBLEM TO BE SOLVED: To achieve both reduction of a vehicle body slip angle and insurance of a target yaw rate. SOLUTION: The steering device is provided with LSD 9 provided between a right side rear wheel 6a and a left side rear wheel 6b and capable of changing distribution of driving force transmitted from an engine to the rear wheels 6a, 6b; a front wheel steering actuator 7 for varying steering angles of the front wheels 4a, 4b; a rear wheel steering actuator 8 for varying steering angles of the rear wheels 6a, 6b; and a four-wheel steering controller 10 for outputting control instruction for varying the steering angle to the front wheel steering actuator 7 and the rear wheel steering actuator 8 in response to the traveling state. When engine torque is not varied, the four-wheel steering controller 10 outputs the control instruction for making the front wheel steering angle and the rear wheel steering angle large in proportion to a control current value of the LSD 9.
