PURPOSE:To avoid the need of the mechanical connection of the steering means for front and rear wheels by steering rear wheels by a steering means which utilizes a subframe which can be turned and installed separately from the steering means for front wheels. CONSTITUTION:A power cylinder 22 for turning a subframe 6 is allowed to cross with the centrifugal direction around the pivot 7 of the subframe 6, and the both edges are pivotally installed onto the cross members 5 of the subframe 6 and a main frame 1. The power cylinder 2 is connected with a hydraulic driving means 23 for controlling the hydraulic pressure, and is operated by allowing the hydraulic driving means 23 to receive the control instruction corresponding to the operation state of the car from a control means 24. The control means 24 receives the signal of a car speed sensor 25, front wheel steering angle sensor 26, and the right and left rear wheel revolution speed sensors 27 and 28 as the detection signal for the operation state of the car. |
