PROBLEM TO BE SOLVED: To lighten total weight, and increase the performance of machinery, by studying thoroughly the lightening of weight of parts one by one. SOLUTION: In the case of a bicycle, the portion of a tire, a tire cover, a rim, and a handle, etc., is lightened and thickened as much as possible, and gas 1 lighter than air, e.g. hydrogen, helium, a lamp gas, or a hot air, etc., is packed in the inside of the portion to make the difference of specific gravity voyancy to lighten the whole gross weight. Here, it is useless that the whole gross weight become heavy in order to thicken the tire, the tire cover, the rim, and the handle, etc., consequently it is considered in respective parts to jointly use a main body portion such as aluminum, etc., and an airtight auxiliary portion 2 such as vinyl, etc. In the case of a vehicle, a stream-line bag as large as possible is prepared on a roof to pack gas 1 light than air into the bag as if an airship to make the difference of specific gravity voyancy to lighten the whole gross weight. The vehicle can be nimbly maneuvered and operated even in the highest output and torque by the somewhat lightening of the whole gross weight. |
