PURPOSE: To improve the stability of a vehicle at the time of transient turning by constructing an automobile suspension device in such a way as to drive the outer end of a lower arm to the rear side of a vehicle on the turning outer wheel side by the signal of a turning direction detecting means and to drive the outer end of a lower arm to the front side of the vehicle on the turning inner wheel side.

CONSTITUTION: At the time of turning to the left, for instance, a cylinder 60 is driven to the right, and pressure in a cylinder chamber 74 is lowered, while pressure in a cylinder chamber 76 is enlarged. This pressure is transmitted into the internal spaces 46R, 46L of bush devices 32R, 32L by conduits 78, 80, and the lower arm 20R of a right front wheel 16R, a turning outer wheel, is pivotally rotated clockwise around the center O2 of a front side bush device 30R so as to move a ball joint 28R to the rear side of a vehicle. Inversely, the ball joint 28L of the lower arm 20L of a left side front wheel 16L, is moved to the front side of the vehicle. The position of the vehicle at the time of transient turning is thereby stabilized.
