In this report, the synthetic angle of the front steering position in the two-wheeled vehicle is explained in terms of the camber angle, the steering angle, and a great caster angle in the front-wheel. It helps the running-stability improve. If the caster angle is increased by the leaned steering axis, the stability at straight running is increase, however in that case, immediate escape from the danger of an accident is very difficult, because the two-wheeled vehicle can not smoothly turn when the stability is strong. So, when the system of the front alignment with a great camber angle is incorporated into the rear-steering system, the two-wheeled vehicle gets the improvement of running- stability and controllability. On some patterns of steering positions, relations between the camber angle and the steering angle are shown by numerical calculations. As a result, it is found that the two-wheel steering system of the two-wheeled vehical is easy to turn when its rear wheel is steered in the opposite direction to the front wheel; on the other hand, when the rear wheel is steered in the same direction as the front wheel, the amount of the turning radius becomes greater than in the opposite and the neutral direction.
