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 can be smoothly deformed downward in the height direction of the vehicle, triggered by the groove portion provided at the intersection with the extension portion.
　第２発明の車両のカウルルーバは、第１発明の車両のカウルルーバにおいて、溝部は、車幅方向に延びている。本発明の溝部は、延長部と支持部とに沿うように、車幅方向に延びている。このため延長部に流下する水を、溝部を通じて車幅方向に導けるようになると共に、この溝部をきっかけとして、衝撃荷重が加えられた支持部がよりスムーズに変形できるようになる。 The vehicle cowl louver of the second invention is the vehicle cowl louver of the first invention, wherein the groove extends in the vehicle width direction. The groove portion of the present invention extends in the vehicle width direction along the extension portion and the support portion. Therefore, the water flowing down to the extension can be guided in the vehicle width direction through the groove, and the groove can be used as a trigger to smoothly deform the support section to which the impact load is applied.
　第３発明の車両のカウルルーバは、第１発明又は第２発明の車両のカウルルーバにおいて、溝部は、カウルルーバを意匠面側からその反対の裏面側に貫通する排水孔に通じている。本発明では、フロントガラスから延長部に流下した水を、交差箇所に形成された溝部を通じて、カウルルーバに設けられた排水孔に導けるようになる。 The vehicle cowl louver of the third invention is the vehicle cowl louver of the first invention or the second invention, wherein the groove communicates with a drain hole penetrating the cowl louver from the design side to the opposite back side. In the present invention, the water that has flowed down from the windshield to the extension can be guided to the drain hole provided in the cowl louver through the groove formed at the intersection.
　第４発明の車両のカウルルーバは、第１発明～第３発明のいずれかの車両のカウルルーバにおいて、車両の高さ方向上側に突出する凸部が複数形成された領域に、延長部と立壁部の交差箇所の少なくとも一部が位置しているとともに、溝部は、フロントガラス側からエンジンフード側に延びる複数又は単数の凸部を分断するように形成されている。本発明では、平常時における交差箇所の強度を凸部の設けられた領域にて確保する。そして衝撃荷重が加えられた支持部は、領域内の凸部を分断する溝部をきっかけとして、車両の高さ方向下側に変形できるようになる。 A vehicle cowl louver according to a fourth aspect of the invention is the vehicle cowl louver according to any one of the first to third aspects of the invention, in which an extension portion and a standing wall portion are formed in a region in which a plurality of protrusions projecting upward in the height direction of the vehicle are formed.

［延長部と支持部の交差箇所］
　そしてカウルルーバ１０には、図２～図４を参照して、支持部３０の後立壁部３１と延長部２０との交差箇所２５が車幅方向に延びるように形成されている。この交差箇所２５は、後立壁部３１の基端と延長部２０の前端の境目であり、図２に示すように、延長部２０において最も低い前端位置に形成されている。また図３及び図４に示すように、交差箇所２５の左寄りの部分（一部）は、上述した外気導入部１２と重なっており、この外気導入部１２の中央位置の蓋部位５１を横切るように形成されている。そして中央位置の蓋部位５１には、交差箇所２５と重なる位置に、後述する溝部６０が形成されている。 [Intersection of extension and support]
2 to 4, the cowl louver 10 is formed with an intersection 25 between the rear wall portion 31 of the support portion 30 and the extension portion 20 so as to extend in the vehicle width direction. This intersection point 25 is a boundary between the base end of the rear wall portion 31 and the front end of the extension portion 20, and is formed at the lowest front end position of the extension portion 20 as shown in FIG. Further, as shown in FIGS. 3 and 4, the portion (part) on the left side of the intersection 25 overlaps with the outside air introduction portion 12 described above, and crosses the lid portion 51 at the center position of the outside air introduction portion 12. is formed in A groove portion 60, which will be described later, is formed in the cover portion 51 at the central position at a position overlapping the intersection portion 25. As shown in FIG.
［溝部］
　図５に示す溝部６０は、中央位置の蓋部位５１の上面、即ち、交差箇所２５の意匠面側に形成されている（図５では、便宜上、中央位置の蓋部位５１にハッチを付けて図示する）。この溝部６０は、中央位置の蓋部位５１を横断しつつ、延長部２０と支持部３０の後立壁部３１とに沿うように車幅方向に延びている。そして溝部６０は、図５及び図６に示すように、延長部２０の前端（最も低い部分）と後立壁部３１の基端の境に形成されており、中央位置の蓋部位５１上の複数の前後凸部１３を車両前後方向に分断している。また外気導入部１２に形成された溝部６０は、図７に示すように外気導入部１２と同様に右下がりの傾斜が付けられており、左側から右側に向かうにつれて次第に車両の高さ方向下側に傾斜している。そして図５及び図８を参照して、溝部６０の最も低い位置にある右端は、中央位置の蓋部位５１の右側に位置する排水孔１６に通じている。 [Groove part]
The groove portion 60 shown in FIG. 5 is formed on the upper surface of the lid portion 51 at the central position, that is, on the design surface side of the intersection 25 (in FIG. 5, the lid portion 51 at the central position is hatched for convenience. do). The groove portion 60 extends in the vehicle width direction along the extension portion 20 and the rear wall portion 31 of the support portion 30 while traversing the central lid portion 51 . 5 and 6, the groove portion 60 is formed at the boundary between the front end (lowest portion) of the extension portion 20 and the base end of the rear wall portion 31. are divided in the vehicle front-rear direction. As shown in FIG. 7, the groove 60 formed in the outside air introduction portion 12 is inclined downward to the right in the same manner as the outside air introduction portion 12, and gradually lowers in the height direction of the vehicle as it goes from the left side to the right side. inclined to 5 and 8, the lowest right end of the groove portion 60 communicates with the drain hole 16 located on the right side of the lid portion 51 at the central position.
　ここで図５及び図７を参照して、車両前後方向における溝部６０の形成位置は、その車幅方向両側の左右凸部１４の位置に合わせられている。このため、カウルルーバ１０の意匠面側では、溝部６０と左右凸部１４とが一連となるような外観を呈し、この溝部６０が過度に目立たないようになっている。なお図７及び図８を参照して、溝部６０の右側に隣接する左右凸部１４０は、車両の高さ方向上側の部分が切り欠かれており、溝部６０の底面と概ね面一となるように半円状となっている。即ち、隣接する左右凸部１４０は、溝部６０の一部を構成している。このため、後述するように溝部６０に流れる水は、隣接する左右凸部１４０に極力邪魔されることなく排水孔１６に流れ落ちるようになる。 5 and 7, the formation positions of the grooves 60 in the vehicle front-rear direction are aligned with the positions of the left and right protrusions 14 on both sides in the vehicle width direction. Therefore, on the design surface side of the cowl louver 10, the groove 60 and the right and left projections 14 appear to be continuous, and the groove 60 is not excessively conspicuous. 7 and 8 , left and right projections 140 adjacent to the right side of groove 60 are notched at the upper side in the height direction of the vehicle so as to be substantially flush with the bottom surface of groove 60 . It has a semicircular shape. That is, the adjacent left and right convex portions 140 constitute a part of the groove portion 60 . Therefore, as will be described later, the water flowing through the groove 60 flows down into the drain hole 16 without being obstructed by the adjacent left and right protrusions 140 as much as possible.
［カウルルーバの性能（溝部の働き）］
　図２示すカウルルーバ１０では、フロントガラス７から延長部２０に流下した雨水等の排水性を確保することが望ましい。またカウルルーバ１０では、その支持部３０の形状等の制約に関わらず、衝撃吸収性を確保することが望ましい。そこでカウルルーバ１０では、その延長部２０が、フロントガラス７の下端部からエンジンフード８に向けて延びていると共に、支持部３０には、延長部２０のエンジンフード８側の端から車両の高さ方向上側に立ち上がる後立壁部３１が形成されている。そして延長部２０と後立壁部３１の意匠面側の交差箇所２５には溝部６０が形成されており、この溝部６０によって、カウルルーバ１０の排水性と衝撃吸収性を確保することとしている。 [Performance of the cowl louver (function of the groove)]
It is desirable for the cowl louver 10 shown in FIG. Further, it is desirable that the cowl louver 10 ensure shock absorption regardless of restrictions such as the shape of the support portion 30 . Therefore, in the cowl louver 10 , the extension 20 extends from the lower end of the windshield 7 toward the engine hood 8 . A rear wall portion 31 is formed that rises upward in the direction. A groove portion 60 is formed at the intersection 25 of the extension portion 20 and the rear standing wall portion 31 on the design surface side.
［カウルルーバの排水性］
　上記構成によると、図５及び図６に示す延長部２０と後立壁部３１の交差箇所２５に設けられた溝部６０を、フロントガラス７から流下する水の排水路として利用できるようになる（各図では、水の流れる向きを示す矢線に符号Ｗを付す）。即ち、フロントガラス７から流下した雨水等は、延長部２０に沿って車両前側に流れたのち、この延長部２０の前端に設けられた溝部６０に流れ落ちる。この溝部６０は、上述したように右下がり傾斜が付けられていると共に、その溝部６０の右端が、中央位置の蓋部位５１の右側に位置する排水孔１６に通じている。このため図５～図８を参照して、溝部６０に流れ落ちた水は、車幅方向となる左側から右側に向けて流れていき、溝部６０の右側に配置された排水孔１６に導かれるようになる。こうして上記構成によれば、フロントガラス７から延長部２０に流下した雨水等を、溝部６０を通じて排水孔１６に導けるようになり、とりわけ最も低い位置にある延長部２０と後立壁部３１の交差箇所２５に水が溜まり難くなる。また洗車時の際には、洗車用具によって延長部２０上の水を車幅方向に押し流しながら拭き取ることがある。このような場合にも、拭き残しの水を溝部６０から排水孔１６に排水できるようになり、優れた洗車性の確保に資する構成となる。 [Drainage of cowl louvers]
According to the above configuration, the groove portion 60 provided at the intersection 25 between the extension portion 20 and the rear wall portion 31 shown in FIGS. In the figure, the arrow indicating the direction of water flow is denoted by W). That is, rainwater or the like that has flowed down from the windshield 7 flows along the extension 20 toward the front of the vehicle, and then flows down into the groove 60 provided at the front end of the extension 20 . The groove portion 60 is inclined downward to the right as described above, and the right end of the groove portion 60 communicates with the drain hole 16 located on the right side of the lid portion 51 at the central position. Therefore, referring to FIGS. 5 to 8, the water flowing down into the groove 60 flows from the left side to the right side in the vehicle width direction, and is guided to the drain hole 16 arranged on the right side of the groove section 60. become. In this way, according to the above configuration, rainwater or the like that has flowed down from the windshield 7 to the extended portion 20 can be guided to the drain hole 16 through the groove portion 60. It becomes difficult for water to accumulate at 25. In addition, when washing the car, the water on the extension 20 may be wiped off while being washed away in the vehicle width direction with a car washing tool. Even in such a case, water left unwiped can be drained from the groove portion 60 to the drain hole 16, which contributes to ensuring excellent car washability.
［カウルルーバの衝撃吸収性］
　また上記構成では、図２に示すエンジンフード８に加わる衝撃荷重Ｆを、カウルルーバ１０の支持部３０が車両の高さ方向下側に変形することで吸収する（図２中、二点破線で示す支持部を参照）。そしてカウルルーバ１０では、その支持部３０の山状部３００が車両の高さ方向に立ち上がっており、エンジンフード８から加わる衝撃荷重Ｆを受けられるようになっている。この山状部３００は、その後立壁部３１の基端（交差箇所２５）を屈曲の基点として、車両の高さ方向下側に屈曲変形する。そこでカウルルーバ１０では、後立壁部３１の基端（交差箇所２５）に設けられた溝部６０が、山状部３００の後立壁部３１に沿うように車幅方向に延びている。このため衝撃荷重Ｆの加えられた支持部３０の山状部３００は、その後立壁部３１に沿うように形成された溝部６０をきっかけとして、車両の高さ方向下側にスムーズに変形できるようになる。こうしてカウルルーバ１０では、交差箇所２５に形成された溝部６０を利用して支持部３０がスムーズに変形できるため、支持部３０の形状上の制約に関わらず、衝撃吸収性を確保することができる。また支持部３０の変形の基点として溝部６０を意図的に用いることで、この支持部３０の変形の際に、カウルルーバ１０の意図しない箇所の破損（折損）を極力回避できるようになる。 [Impact absorption of cowl louvers]
In the above configuration, the impact load F applied to the engine hood 8 shown in FIG. 2 is absorbed by the support portion 30 of the cowl louver 10 deforming downward in the height direction of the vehicle (indicated by a two-dot dashed line in FIG. 2). support). In the cowl louver 10, the mountain-like portion 300 of the support portion 30 rises in the height direction of the vehicle so that the impact load F applied from the engine hood 8 can be received. The mountain-like portion 300 bends and deforms downward in the height direction of the vehicle with the base end (intersection point 25) of the rear wall portion 31 as the base point of bending. Therefore, in the cowl louver 10 , a groove portion 60 provided at the base end (intersection point 25 ) of the rear wall portion 31 extends in the vehicle width direction along the rear wall portion 31 of the mountain-like portion 300 . Therefore, the mountain-shaped portion 300 of the support portion 30 to which the impact load F is applied is smoothly deformed downward in the height direction of the vehicle, triggered by the groove portion 60 formed along the rear wall portion 31. Become. In this way, in the cowl louver 10, the support part 30 can be smoothly deformed by using the groove part 60 formed at the intersection 25, so that impact absorption can be ensured regardless of the restriction on the shape of the support part 30. - 特許庁Further, by intentionally using the groove portion 60 as a base point for deformation of the support portion 30, damage (breakage) of unintended portions of the cowl louver 10 can be avoided as much as possible when the support portion 30 is deformed.
　以上説明した通り本実施例では、意匠面側の交差箇所２５に形成された溝部６０を、フロントガラス７から延長部２０に流下する水の排水路として利用できるようになる。またエンジンフード８に加わる衝撃荷重Ｆを、カウルルーバ１０の支持部３０が車両の高さ方向下側に変形することで吸収する。このとき支持部３０は、延長部２０との交差箇所２５に設けられた溝部６０をきっかけとして、車両の高さ方向下側にスムーズに変形できるようになる。このため本実施例によれば、カウルルーバ１０の排水性と衝撃吸収性をより確実に確保することができる。 As described above, in this embodiment, the groove 60 formed at the intersection 25 on the design surface side can be used as a drainage channel for water flowing down from the windshield 7 to the extension 20 . Further, the impact load F applied to the engine hood 8 is absorbed by the support portion 30 of the cowl louver 10 deforming downward in the height direction of the vehicle. 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.
