摘要： PROBLEM TO BE SOLVED: To feed operation oil of a flow rate corresponding to a steering speed to a steering cylinder without detecting a steering angle of a steering wheel. SOLUTION: A controller 45 controls left wheel and right wheel driving motors respectively so that angular velocities of left and right driving wheels become equal against a rotation center of a vehicle based on a tire angle θ detected by a tire angle sensor 42. The controller 45 determines a steering speed of a steered wheel 14 when the steering wheel 22 is steered from the tire angle θ detected by the tire angle sensor 42. A hydraulic motor 31 is controlled based on the steering speed and a flow rate of operation oil corresponding to the steering speed is fed from a hydraulic pump 32 to a steering cylinder 35 through a priority valve 33.
