A portion of the main body plate portion 56 of the rear shielding plate 40B where the third air passage portion 46C is not provided is located. Further, the third air passage portion 46C is arranged on the downstream side in the flow direction of the air A at the portion where the first air passage portion 46A and the second air passage portion 46B of the main body plate portion 44 of the front shielding plate 40A are not provided. ing.

次に作用効果について説明する。
本実施の形態では、空気取り入れ口２２０２より車両前方に車両前後方向に間隔をおいて複数の遮蔽板４０が設けられる。隣り合う前遮蔽板４０Ａおよび後遮蔽板４０Ｂに設けられた第１～第３空気通過部４６Ａ～４６Ｃは空気の流れ方向で互いに重ならないように配置されている。言い換えると、前遮蔽板４０Ａおよび後遮蔽板４０Ｂに、車幅方向および上下方向の位相をずらして空気Ａの通過を可能とした第１～第３空気通過部４６Ａ～４６Ｃが、設けられている。
したがって、前遮蔽板４０Ａの本体板部４４、後遮蔽板４０Ｂの本体板部５６、第１～第３空気通過部４６Ａ～４６Ｃにより構成される流路構造が、いわゆるラビリンス構造（迷路構造）を構成する。このため、フロントグリル１４の開口１４０２から空気取り入れ口２２０２に向かって導かれる空気Ａに雪などの異物が混入した場合に、ラビリンス構造によってそれら異物の空気取り入れ口２２０２への侵入が防止される。この結果、異物のエアクリーナ２２への侵入が防止される。
そのため、エンジン２０の燃焼効率を確保して燃費の向上を図る上で有利となる。
また、後遮蔽板４０Ｂは、アッパーフレーム３４に設けられフェンダーパネル１６を支えるフェンダーブラケット４８で構成される。すなわち、ラビリンス構造が、フェンダーパネル１６を支えるフェンダーブラケット４８を利用して構成される。このため、部品点数の抑制を図り、コストダウンを図る上で有利となる。Next, the action and effect will be described.
In the present embodiment, a plurality of shielding plates 40 are provided in front of the vehicle from the air intake 2202 at intervals in the front-rear direction of the vehicle. The first to third air passage portions 46A to 46C provided on the adjacent front shielding plate 40A and the rear shielding plate 40B are arranged so as not to overlap each other in the air flow direction. In other words, the front shielding plate 40A and the rear shielding plate 40B are provided with first to third air passing portions 46A to 46C that allow the passage of air A by shifting the phases in the vehicle width direction and the vertical direction. ..
Therefore, the flow path structure composed of the main body plate portion 44 of the front shielding plate 40A, the main body plate portion 56 of the rear shielding plate 40B, and the first to third air passage portions 46A to 46C has a so-called labyrinth structure (maze structure). Configure. Therefore, when foreign matter such as snow is mixed in the air A guided from the opening 1402 of the front grill 14 toward the air intake port 2202, the labyrinth structure prevents the foreign matter from entering the air intake port 2202. As a result, foreign matter is prevented from entering the air cleaner 22.
Therefore, it is advantageous in ensuring the combustion efficiency of the engine 20 and improving the fuel efficiency.
Further, the rear shielding plate 40B is composed of a fender bracket 48 provided on the upper frame 34 and supporting the fender panel 16. That is, the labyrinth structure is configured by using the fender bracket 48 that supports the fender panel 16. Therefore, it is advantageous in reducing the number of parts and reducing the cost.

また、遮蔽板４０は、フェンダーパネル１６の前端部に設けられフェンダー空間ＳＦ内への空気の流入を規制する後遮蔽板４０Ｂと、後遮蔽板４０Ｂより空気の流れの上流側に設けられる前遮蔽板４０Ａとを含んでいる。
後遮蔽板４０Ｂがフェンダー空間ＳＦの前に設けられているので、フェンダー空間ＳＦ内に異物が溜まることが抑制される。このため、空気の流れにより舞い上げられた異物が空気取り入れ口２２０２へ侵入することが防止される。この結果、エンジン２０の燃焼効率が確保さえ、燃費が向上する。Further, the shielding plate 40 includes a rear shielding plate 40B provided at the front end portion of the fender panel 16 to regulate the inflow of air into the fender space SF, and a front shielding plate 40 provided on the upstream side of the air flow from the rear shielding plate 40B. Includes plate 40A.
Since the rear shielding plate 40B is provided in front of the fender space SF, it is possible to prevent foreign matter from accumulating in the fender space SF. Therefore, foreign matter blown up by the air flow is prevented from entering the air intake port 2202. As a result, even if the combustion efficiency of the engine 20 is ensured, the fuel efficiency is improved.

また、後遮蔽板４０Ｂに設けられる第３空気通過部４６Ｃは、後遮蔽板４０Ｂの車幅方向外側の端部を切り欠いた欠部５６１０で形成されている。このため、エンジンルームから遠くより温度の低い空気が積極的に空気取り入れ口２２０２に取り入れられ、燃費が向上する。
また、フロントサイドフレーム３４に設けられた空気取り入れ口２２０２に空気を導く際に、欠部５６１０で形成された第３空気通過部４６Ｃによりフロントサイドフレーム３４から車幅方向で離れた箇所から空気が導かれる。このため、空気の流れがより安定する。Further, the third air passage portion 46C provided in the rear shielding plate 40B is formed by a notch 5610 notched at the outer end portion of the rear shielding plate 40B in the vehicle width direction. Therefore, air having a lower temperature than far from the engine room is positively taken into the air intake port 2202, and fuel efficiency is improved.
Further, when the air is guided to the air intake port 2202 provided in the front side frame 34, the air is discharged from a portion separated from the front side frame 34 in the vehicle width direction by the third air passing portion 46C formed by the missing portion 5610. Be guided. Therefore, the air flow becomes more stable.

また、前遮蔽板４０Ａに設けられる第１、第２空気通過部４６Ａ、４６Ｂは、前遮蔽板４０Ａを貫通する開口４４１０、４４１２により形成される。開口４４１０、４４１２は、前遮蔽板４０Ａの空気の流れ方向の下流側に凹んだ凹部４４０４、４４０６内に設けられている。
したがって、図６に示すように、第１空気通過部４６Ａおよび第２空気通過部４６Ｂを通過する空気Ａに乱流Ｆが生じやすくなる。乱流Ｆによって雪などの異物が第１空気通過部４６Ａおよび第２空気通過部４６Ｂを通過しにくくなる。このため、異物のエアクリーナ２２への侵入を防止する上でより有利となり、エンジン２０の燃焼効率を確保して燃費の向上を図る上でより有利となる。Further, the first and second air passage portions 46A and 46B provided in the front shielding plate 40A are formed by openings 4410 and 4412 penetrating the front shielding plate 40A. The openings 4410 and 4412 are provided in the recesses 4404 and 4406 recessed on the downstream side of the front shielding plate 40A in the air flow direction.
Therefore, as shown in FIG. 6, turbulent flow F is likely to occur in the air A passing through the first air passing portion 46A and the second air passing portion 46B. The turbulent flow F makes it difficult for foreign matter such as snow to pass through the first air passage portion 46A and the second air passage portion 46B. Therefore, it is more advantageous in preventing foreign matter from entering the air cleaner 22, and it is more advantageous in ensuring the combustion efficiency of the engine 20 and improving fuel efficiency.

また、空気取り入れ口２２０２に向かって導かれる空気Ａに雪などの異物が混入している場合に、雪などの異物は、最も車両前方に位置する前遮蔽板４０Ａに衝突して下方に落下する割合が大きい。
本実施の形態では、最も車両前方に位置する前遮蔽板４０Ａは、車両前方に至るに連れて次第に下方に変位するスプラッシュシールド３６の傾斜部３６０２の上方に配置される。このため、前遮蔽板４０Ａにより空気Ａから取り除いた異物が前遮蔽板４０Ａの前方に蓄積することが抑制される。
したがって、異物のエアクリーナ２２への侵入を防止する上でより有利となり、エンジン２０の燃焼効率を確保して燃費の向上を図る上でより有利となる。Further, when foreign matter such as snow is mixed in the air A guided toward the air intake port 2202, the foreign matter such as snow collides with the front shielding plate 40A located most in front of the vehicle and falls downward. The ratio is large.
In the present embodiment, the front shielding plate 40A located at the front of the vehicle is arranged above the inclined portion 3602 of the splash shield 36 which is gradually displaced downward toward the front of the vehicle. Therefore, foreign matter removed from the air A by the front shielding plate 40A is suppressed from accumulating in front of the front shielding plate 40A.
Therefore, it is more advantageous in preventing foreign matter from entering the air cleaner 22, and is more advantageous in ensuring the combustion efficiency of the engine 20 and improving fuel efficiency.
