To make a wind pass through an intercooler by eliminating a wind which stagnates in the vicinity of a protrusion piece at an upper face of the intercooler.SOLUTION: A duct 5 opened at a vehicle front side, and surrounded by left and right sidewalls 10 is arranged on an intercooler 3, and a protruding piece 18 protruding with a gap between an upper face of the intercooler 3 and itself is arranged at an opening 12 of the duct 5. A penetration hole 21 is formed at a sidewall 10 in the vicinity of the protruding piece 18 at a side at which an introduction wind introduced into the duct 5 stagnates on an upper face of the intercooler 3 at the traveling of a vehicle. The wind which stagnates without passing through the intercooler 3 is discharged to the outside of the duct 5 from the penetration hole 21. A wind stagnation in a stagnated region is suppressed, a circumferential wind flows in, and a volume of the wind which passes through the intercooler 3 is increased.SELECTED DRAWING: Figure 1

    【課題】インタークーラの上面で突出片近傍に滞留する風をなくして、インタークーラを通り抜けるようにする。【解決手段】インタークーラ3上に、車両前方側が開口され、左右の側壁10で囲まれたダクト5が設けられ、ダクト5の開口12に、インタークーラ3の上面と間隙をもって突出する突出片18が設けられる。車両走行時、ダクト5への導入風がインタークーラ3の上面で滞留している側の突出片18近傍の側壁10に貫通孔21設けられる。インタークーラ3を通り抜けずに滞留した風は貫通孔21からダクト5の外部に排出される。滞留していた領域で風の滞留が減って、周囲の風が流れ込み、インタークーラ3を通り抜ける風が増える。【選択図】図1
