To solve the problem that a slip occurs in a wheel grounding surface as a camber angle is changed.
Upper arms 26L, 26R to be connected to wheels 12L, 12R are connected to both ends of a movable bar 24. An electric motor 20 drives a movable bar 24 to incline the wheels 12L, 12R, and to change the camber angle. Rods 36L, 36R connected to the wheels 12L, 12R are connected to both ends of the movable bar 34. The electric motor 30 drives the movable bar 34 to change the toe angle of the wheels 12L, 12R. A camber angle control amount operation unit in an ECU 110 determines the control amount of the electric motor 20 so as to generate the turn according to the rotational angle of a steering wheel in a vehicle, and a toe angle control amount operation unit refers to the control amount of the camber angle, and when the wheels are inclined to the center side of the turning circle, the control amount of the electric motor 30 is determined so that the wheels are opened outward of the turning circle.
