Abstract
Provided is a vehicle testing apparatus which involves load variation and alignment variation, for analyzing a maneuverability of a vehicle on flat belts or rollers adapted to be rotated together with wheels of the vehicle, and in particular, maneuver variation. Load variation caused by an inertia force and a gravitational force which are produced during actual running of the vehicle, and tire alignment variation caused by suspension strokes, are forcibly reproduced by forces produced by actuators or a gravitational force, thereby it is possible to evaluate a maneuverability of the vehicle in a condition substantially the same as that during actual running of the vehicle.
