Patent ID: 8256780

Claim:
A vehicle steering device, comprising: left and right arm mechanisms placed between a vehicle body and respective wheel-mounting portions, the left and right arm mechanisms each having a front arm and a rear arm, the front arm having one end rotatably connected at a wheel-side front connecting point to the wheel-mounting portion, and the other end rotatably connected at a body-side front connecting point to the vehicle body, the rear arm having one end rotatably connected at a wheel-side rear connecting point to the wheel-mounting portion, and the other end rotatably connected at a body-side rear connecting point to the vehicle body, the wheel-side front connecting point and the wheel-side rear connecting point being spaced apart from each other in a longitudinal direction of a vehicle, the body-side front connecting point and the body-side rear connecting point being spaced apart from each other in the longitudinal direction of the vehicle, the front arm and the rear arm each including a plurality of links, adjacent links of which are rotatably connected to each other at an intermediate connecting point; and an arm driving device that drives the left and right arm mechanisms independently from each other, the arm driving device driving the left and right arm mechanisms such that angles of the links around the body-side front connecting point, the body-side rear connecting point, the intermediate connecting points, the wheel-side front connecting point, and the wheel-side rear connecting point are uniquely determined.
