To reduce air pollution caused by increase in fuel consumption by a vehicle and save fuel in contrast to price rise, to straighten air turbulence and eddy flow generated at a bottom part of a vehicle body during travelling of the vehicle to reduce travelling resistance, to prevent floating up of a rear part of the vehicle body by generating negative pressure under a floor of the vehicle body to secure travelling stability, and to reduce volumes by introducing exhaust from a self-fitted oil motor into a device for cooling at the same time and forcibly suction and discharge the exhaust utilizing generated negative pressure to improve fuel efficiency, while silencing and muffling detonating sound.SOLUTION: An exhaust pipe (3) is connected to a front end part (1A) and an arbitrary volume is secured between the part and a rear end part (1B) to make a volume reduction/sound-muffling chamber, predetermined bulge is provided between an upper surface (1F) and a lower surface (1E), widths in a perpendicular/vertical direction are narrowed toward the rear end part (1B) and the lower surface (1E) is attached to a predetermined position at a bottom part of a vehicle body, toward the ground surface.SELECTED DRAWING: Figure 2

    【課題】車両の燃料消費量増大に伴う、大気汚染の軽減と価格上昇に対する燃料の節約。車両走行時に車体の底部に発生する乱気流、渦流を整流化し、走行抵抗を減少させる。車体床下に負圧を発生させて車体後部の浮上がりを防ぎ、走行安定の確保。同時に自装発動機の排気を装置内に導いて冷却して減容を図り、爆音の静音化、消音化を図りながら、発生負圧を利用して排気を強制吸引排出させて燃費の向上を図る。【解決手段】前端部(1A)に排気管(3)を接続し、後端部(1B)迄の間に任意の容積を確保して減容消音室とし、上面(1F)と下面(1E)の間に所定の膨らみを与え、後端部(1B)に向かうにつれ垂直上下方向を狭め、下面(1E)を地面側に向けて車体底部の所定の位置に取り付ける。【選択図】図2
