The hood contact portion 30X is formed with an upright wall portion 31X that rises from the front end of the connection portion 20X in the height direction of the vehicle. Configure. A seal member 37X that is pressed against the bonnet hood 8X and an air intake 12X are provided on the upper surface of the hood contact portion 30X. This air intake port 12X is a through hole for taking in outside air, and is also used for drainage of rainwater and the like.
 また図9に示すカウルトップカバー10Xでは、そのフード当接部30Xが車両の高さ方向下側に延びる縦壁35Xを介して車体パネル90Xに支持されている。この縦壁35Xは、車両前側が解放された横U字に形成されていると共に、その縦壁35Xの車両前側は、車両の高さ方向に延びる板状の補強リブ36Xにて補強されている。そして縦壁35Xと補強リブ36Xとには、それぞれ溝状の屈曲線XLが車両の高さ方向中央に形成されている。上記構成では、ボンネットフード8Xに加わる衝撃荷重をフード当接部30Xが車両の高さ方向下側に変形することで吸収する。このとき縦壁35X及び補強リブ36Xが対応する屈曲線XLを基点に折れ曲がるため、フード当接部30Xがスムーズに変形できるようになる。 Further, in the cowl top cover 10X shown in FIG. 9, the hood contact portion 30X is supported by the vehicle body panel 90X via the vertical wall 35X extending downward in the height direction of the vehicle. The vertical wall 35X is formed in a horizontal U shape with the vehicle front side open, and the vehicle front side of the vertical wall 35X is reinforced by a plate-shaped reinforcing rib 36X extending in the height direction of the vehicle. . The vertical wall 35X and the reinforcing rib 36X are each formed with a groove-shaped bending line XL at the center in the height direction of the vehicle. In the above configuration, the impact load applied to the bonnet hood 8X is absorbed by the hood contact portion 30X deforming downward in the height direction of the vehicle. At this time, since the vertical wall 35X and the reinforcing rib 36X are bent around the corresponding bending line XL, the hood contact portion 30X can be smoothly deformed.
 ところで上記カウルトップカバー10X(カウルルーバ)では、空気取り入れ口12Xが水の排水に利用されるが、この空気取り入れ口12Xは接続部20Xよりも高い位置に形成されている。このためフロントガラス7Xから流下した雨水等が接続部20Xと立壁部31Xとの交差箇所25Xに溜まった場合、この溜まった雨水等を排水し難くなる。また上記カウルトップカバー10Xでは、衝撃吸収性の確保のために縦壁35Xと補強リブ36Xとに屈曲線XLが形成されるが、当該構成は、車種によってはカウル形状の制約等で採用できない場合がある。本発明は上述の点に鑑みて創案されたものであり、本発明が解決しようとする課題は、カウルルーバの排水性と衝撃吸収性をより確実に確保することにある。 By the way, in the cowl top cover 10X (cowl louver), the air intake 12X is used for water drainage, and the air intake 12X is formed at a position higher than the connecting portion 20X. Therefore, when rainwater or the like flowing down from the windshield 7X accumulates at the intersection 25X between the connecting portion 20X and the standing wall portion 31X, it is difficult to drain the collected rainwater or the like. Further, in the cowl top cover 10X, the bending line XL is formed between the vertical wall 35X and the reinforcing rib 36X in order to ensure shock absorption. There is The present invention has been made in view of the above points, and an object of the present invention is to more reliably secure drainage and impact absorption of the cowl louver.

At this time, the support portion 30 can smoothly deform downward in the height direction of the vehicle, triggered by the groove portion 60 provided at the intersection 25 with the extension portion 20 . Therefore, according to this embodiment, it is possible to more reliably ensure the drainage and impact absorption of the cowl louver 10 .
 さらに本実施例の溝部60は、延長部20と支持部30とに沿うように、車幅方向に延びている。このため延長部20に流下する水を、溝部60を通じて車幅方向に導けるようになると共に、この溝部60をきっかけとして、衝撃荷重Fが加えられた支持部30がよりスムーズに変形できるようになる。また本実施例では、フロントガラス7から延長部20に流下した水を、交差箇所25に形成された溝部60を通じて、カウルルーバ10に設けられた排水孔16に導けるようになる。そして本実施例では、平常時における交差箇所25の強度を凸部13,14の設けられた領域(外気導入部12)にて確保する。そして衝撃荷重Fが加えられた支持部30は、領域内の凸部(13)を分断する溝部60をきっかけとして、車両の高さ方向下側に変形できるようになる。 Furthermore, the groove portion 60 of this embodiment extends in the vehicle width direction along the extension portion 20 and the support portion 30 . Therefore, the water flowing down to the extension portion 20 can be guided in the vehicle width direction through the groove portion 60, and the groove portion 60 serves as a trigger for smoother deformation of the support portion 30 to which the impact load F is applied. . Further, in this embodiment, water flowing down from the windshield 7 to the extended portion 20 can be guided to the drain hole 16 provided in the cowl louver 10 through the groove portion 60 formed at the intersection 25 . In this embodiment, the strength of the crossing point 25 in a normal state is ensured by the region (outside air introducing portion 12) provided with the projections 13 and 14. FIG. Then, the support portion 30 to which the impact load F is applied becomes deformable downward in the height direction of the vehicle, triggered by the groove portion 60 that divides the convex portion (13) in the area.
