To provide a vehicular engine hood structure which has a little air resistance when a vehicle is running, prevents water rain from entering in a rainy day, and capable of discharging heat from a heat generating body like an engine.SOLUTION: A front surface plate 2, a back surface plate 3, and a circumference edge 4 are joined to form an internal space 5 therein. The back surface plate 3 immediately above a heat generating body is caused to protrude upwardly so as to form a flange 7. An inlet port 8 in communication with the internal space 5 is provided in the flange 7. A discharge port 9 is formed at a position in the front surface plate 2 shifted in the horizontal direction relative to the flange 7. A ceiling 10 may be provided at the flange 7. A vane wall which extends in the back-and-forth direction and which protrudes downwardly may be provided at the center part of the ceiling 10.SELECTED DRAWING: Figure 6

    【課題】走行時の空気抵抗が小さく、雨天時の雨水の侵入を防ぎつつ、エンジン等の発熱体からの熱気を排出できるようにした自動車用ボンネットの構造を提供する。【解決手段】表面板2と裏面板3とを周縁部4を接合して内部に内部空間5を形成し、発熱体の直上部の裏面板3を上方に突出させてフランジ部7を形成し、該フランジ部7に内部空間5に連通する吸気口8を設け、フランジ部7に対して左右方向に位置をずらせた表面板2の位置に排気口9を形成した。フランジ部7に天井10を設けることができる。天井10の中央部に前後方向に延び下方に突出する分流壁を設けることもできる。【選択図】図6
