PROBLEM TO BE SOLVED: To solve problems for example, in a conventional vehicle having a box type rear deck, during travel, a negative pressure region which is generated on a rear side serves as resistance, so that fuel consumption performance is deteriorated.SOLUTION: A plate having a hole for air discharge on the central vicinity is attached to a rear part of a box type rear deck, with a space between the plate and the rear deck, in which the plate has size almost equal to size of a rear face of the rear deck, so that when a truck travels, air which is taken from surrounding of the box type rear deck can be discharged from the hole for air discharge on a rear part of the box type rear deck, so that generation of a negative pressure region during travel can be suppressed, so that travel resistance is reduced, and fuel economy can be improved.SELECTED DRAWING: Figure 1
【課題】 従来の箱形荷台の自動車では、走行時に、後方に発生する負圧域が抵抗となり、燃費性能を低下させる原因となっていた。【解決手段】箱型荷台の後方に、荷台との間に隙間を設けて、荷台の後面とほぼ同じ大きさで、中央付近に空気排出の穴を設けた板を取り付けたので、トラックが走行する時に、箱型荷台の周辺から取り込んだ空気を、箱型荷台の後の空気排出穴から排出出来るようになり、走行中の負圧域の発生が抑制され、走行抵抗が減少し、燃費を向上させる事が出来る。【選択図】図1
