PURPOSE:To simplify a rear wheel steering device in structure as well as to improve reliability in steering operation, by constituting a support device, which supports a suspension arm for rear wheels elastically on a car body, with both outer and inner cylinders and an elastic body and a fluid chamber being set up between these cylinders. CONSTITUTION:When a steering wheel 3 is operated and a rack 5 is moved to a right direction C by way of example, discharge oil flowing from a cylinder device 10 to a line 14 enters a left fluid chamber 23 of support devices 16 and 17 via each of lines 14a and 14b. On the other hand, a right fluid chamber is connected to a left cylinder chamber 10b via a line 15, and since the said chamber 10b is connected to a reservoir 13 as well, the right fluid chamber inside comes to almost nearly atmospheric pressure. As a result, oil pressure inside the left fluid chamber becomes yet higher than the former whereby an outer cylinder is moved in a body left direction E in relation to an inner cylinder 24 attached to a support pin so that rear wheels 2a and 2b are sterred round in a clockwise direction F via each of front suspension arms 33a and 33b. And, each of front wheels 1a and 1b is also steered round in a clockwise direction D. |
