To raise air velocity of airflow flowing from a front side of an engine room along a top face of an undercover and deflected upward at a guide.SOLUTION: A guide 33 continuously extending upward from a top face of an undercover 3 comprises: a left-front wall part 331 linearly extending from left-front to right-rear in a plan view; a right-front wall part 332 which is positioned at a right side relative to the left-front wall part in a vehicle width direction, linearly extending from right-front to left-rear in the plan view; and a rear wall part 333 which is respectively connected to a rear end of the left-front wall part 331 and a rear end of the right-front wall part 332 in a vehicle longitudinal direction. The guide 33 is constructed in which at least one part of the rear wall part 333 linearly extends in a vehicle crosswise direction in the plan view. Thereby, airflow flowing over a wide range from a front side of an engine room 2 along the top face of the undercover 3 is aggregated into the rear wall part 333 to raise air velocity and deflect upward so as to be capable of blowing airflow whose air velocity has enough cooling performance.SELECTED DRAWING: Figure 4

    【課題】エンジンルームの前方からアンダーカバーの上面に沿って流れ、ガイドにおいて上方に偏向される空気流の風速を高める。【解決手段】アンダーカバー3の上面から連続して上に延びるガイド33は、平面視で左前から右後へ直線状に延びる左前壁部331と、左前壁部よりも車幅方向で右方へ位置し、平面視で右前から左後へ直線状に延びる右前壁部332と、左前壁部331と右前壁部332の車両前後方向後端のそれぞれに連続する後壁部333とから成る。そしてガイド33は、後壁部333の少なくとも一部が平面視において車両左右方向に直線状に延びるように構成されている。これによりエンジンルーム2の前方からアンダーカバー3の上面に沿って流れる広い範囲の空気流を後壁部333に集約し風速を高め上方に偏向することで冷却に十分な風速の空気流を送風することができる。【選択図】図4
