PROBLEM TO BE SOLVED: To provide an under cover capable of effectively reducing air resistance at a lower part of a vehicle front portion, while sufficiently ensuring stiffness.SOLUTION: An under cover 10 disposed at a lower part of a vehicle front portion, which has a platy base plate portion 12 leading an air flow: Fc flowing out from an engine room: E to a vehicle rear side; and a rear side rising wall portion 14c formed upward from an end edge portion on the vehicle rear side of the base plate portion 12 so as to rise at predetermined height. On the rear side rising wall portion 14c, a window portion 26 opening to a vehicle rear side is formed, and on a part on the vehicle rear side on the base plate portion 12, a structure 28 for guiding and introducing a part of an air flow: Fu flowing from a vehicle front side to a rear side under the base plate portion 12 is provided.SELECTED DRAWING: Figure 7
【課題】剛性を充分に確保しつつ、車両前部の下部部位における空気抵抗を効果的に低減せしめることが出来るアンダーカバーを提供すること。【解決手段】エンジンルーム:Eから流出せしめられる空気の流れ:Fcを車両後方側に導く平板状の基板部12と、基板部12の車両後方側の端縁部から上方に向かって所定高さで立ち上がるように形成された後側立壁部14cとを有する、車両前部の下部部位に配置されるアンダーカバー10において、後側立壁部14cに、車両後方に向かって開口する窓部26を形成すると共に、基板部12における車両後方側の部位に、基板部12の下方を車両前方から後方に向かって流れる気流:Fuの一部を案内乃至導入するための構造28を設けて、構成した。【選択図】図7
