PROBLEM TO BE SOLVED: To solve the problem that in the case of automobiles, Karman vortex generated during traveling cannot be controlled, resulting in an increased air resistance and poor fuel economy.SOLUTION: Fuel economy is improved by disposing a large number of concave parts (3) so as to decrease Karman vortex and air resistance.SELECTED DRAWING: Figure 1
【課題】 自動車を例にとると、走行時発生するカルマン渦を制御できず、空気抵抗を増やし、燃費を悪くしている。【解決手段】多数の凹部(3)を設けることによりカルマン渦を減らし空気抵抗を減らし、燃費を良くしている。【選択図】図1
