<p>PROBLEM TO BE SOLVED: To provide a wheel which does not go flat, therefore which does not use air pressure.SOLUTION: Air pressure has two functions, namely, a function as a cushioning material and a function of load distribution. Therefore, a wheel which does not use air pressure is subjected to load concentration. In load concentration, a center of gravity is one point. In load distribution, centers of gravity are distributed, so that load distribution is favorable for movement. Therefore, air is not used for preventing a wheel from going flat, and a wheel is divided into an outer wheel and an inner wheel and the cushioning material is interposed therebetween so that the wheel is subjected to load distribution.</p> |
