Further, a part of the air A introduced into the vehicle front space S from the opening 1402 of the front grill 14 is guided to the space S1 from the opening 56 of the fender garnish 42, and the flange portion 1602 and the upper horizontal plate of the upper frame 34. It is sucked into the air intake 2202 of the air cleaner 22 through the gap S2 between the portions 38.
- the fender garnish 42 passes through the vehicle width direction inner side of the upper end of the upper frame 34 and the vehicle width direction inner side of the flange portion 1602 above the air intake 2202. It extends in the front-back direction. Therefore, the high-temperature air warmed by the engine 20 in the vehicle front space S passes through the gap S2 between the flange portion 1602 of the fender panel 16 and the upper lateral plate portion 46 of the upper frame 34 to the fender panel 16.
- the fender garnish 42 prevents the high-temperature air from flowing into the fender space S3 between the upper frame 34 and the upper frame 34 and being sucked into the air cleaner 22 from the air intake 2202.
- the support portion 50 of the fender garnish 42 supports the hood 18 above the flange portion 1602 of the fender panel 16. Therefore, for example, when the head of a pedestrian collides from the upper side of the hood 18 obliquely rearward, the hood 18 deforms downward while deforming the fender garnish 42. As a result, the collision energy can be absorbed before the hood 18 comes into contact with the fender panel 16, the impact absorption performance is improved, and the pedestrian protection performance is improved.
- the shielding portion 45 of the fender garnish 42 is formed in a U shape having a lower plate portion 46, a vertical plate portion 47, and an upper plate portion 48. For this reason, when the head of a pedestrian collides diagonally rearward from above the hood 18, the fender garnish 42 is likely to be deformed downward together with the hood 18. Therefore, the deformation stroke of the hood 18 is secured, and the shock absorbing performance is improved. At this time, the deformation stroke of the hood 18 is further secured by inclining the upper plate portion 48 so as to gradually move upward toward the vehicle width direction outer side, and the shock absorbing performance is improved.

Therefore, when the vehicle is traveling, the air of low temperature introduced into the vehicle front space S from the opening 1402 of the front grill 14 is efficiently introduced into the inside of the fender garnish 42 (fender space S3). As a result, the low temperature air A is sucked into the air cleaner 22 from the air intake 2202, the combustion efficiency of the engine 20 is secured, and the fuel consumption is improved.
- the cross-sectional shape of the front portion 42A of the fender garnish 42 cut along a virtual plane passing through the vehicle width direction and the vertical direction is formed larger than the cross-sectional shape of the rear portion 42B of the fender garnish 42, and the air intake port 2202 is It is provided on the front portion 42A side.

It is formed to be larger than a cross-sectional shape obtained by cutting the space at the rear portion with an imaginary plane passing through the vehicle width direction and the vertical direction.
- the air intake 2202 is located below the vehicle front portion of the fender garnish 42. Therefore, when the vehicle is traveling, the low temperature air introduced into the vehicle front space S from the opening 1402 of the front grill 14 is positively introduced into the fender space S3. As a result, low-temperature air is sucked into the air cleaner 22 from the air intake 2202, the combustion efficiency of the engine 20 is ensured, and the fuel consumption is improved.
- the vertical plate portion 47 of the fender garnish 42 has a vertical plate inclined portion 4702 that inclines outward in the vehicle width direction toward the rear of the vehicle. Due to the vertical plate inclined portion 4702, the space S1 becomes smaller toward the rear of the vehicle. Therefore, it is advantageous for guiding the air having a low temperature to the air intake port 2202.
- the mounting portion 44 is provided with a mounting tool insertion hole 4402 for mounting the mounting part 44 to the upper frame 34, and the mounting tool insertion hole 4402 is a slender long hole that is displaced toward the front of the vehicle as it goes upward. It is formed of 4402A. Therefore, when the head of a pedestrian collides with the hood 18, the fender garnish 42 is likely to be displaced downward and rearward of the vehicle together with the hood 18. Therefore, the deformation stroke of the hood 18 is secured, and the shock absorbing performance is improved.
- a leg portion 5002 that abuts the flange portion 1602 is vertically provided on the support portion 50, and the leg portion 5002 is formed with an inclination that is displaced rearward of the vehicle as it goes downward. Therefore, when the head of the pedestrian collides with the hood 18, the fender garnish 42 is likely to be deformed downward and rearward of the vehicle together with the hood 18.

Abstract
Description
この車両では、走行時に、フロントグリルの開口から車両前部空間に導入された空気が、フェンダーパネルの車幅方向内側とアッパーフレームとの間を通り、エアクリーナの空気取り入れ口に至る。
そのため、車両前部空間内でエンジンにより暖められた温度の高い空気が、フェンダーパネルの上端フランジとアッパーフレームの上端との間の隙間から、フェンダーパネルとアッパーフレームとの間の空間に流れ込み、温度の高い空気が空気取り入れ口からエアクリーナに吸い込まれるおそれがある。
このように温度の高い空気がエアクリーナに供給されると、燃焼効率の低下を招き燃費が低下することが懸念される。
また、本発明の実施の形態によれば、フードの上方から斜め後方に向かって例えば歩行者の頭部が衝突した際、フードはフェンダーガーニッシュを変形させながら下方に変形する。このため、フードがフェンダーパネルに当接する前に衝突エネルギーが吸収される。この結果、衝撃吸収性能が向上し、歩行者保護性能が向上する。
以下の図面において符号UPは車両上方を示し、符号FRは車両前方を示し、符号INは車幅方向内側を示す。
また、車両の左右は、車両の後方から前方を見ていうものとする。
図1、図2に示すように、車両10は、ダッシュパネル12の前方でフロントグリル14の後方に、上方が開閉可能なフード18で仕切られた車両前部空間S(エンジンルーム)を備えている。
車両前部空間Sには、駆動輪を駆動する駆動源としてエンジン20、エンジン20に吸気を供給するエアクリーナ22、インテークマニホールド24、排気を排出する不図示のエキゾーストマニホールド、エンジン20に冷却水を循環させるラジエータ26、などが配置されている。
図1、図2、図4に示すように、フロントグリル14には空気A(走行風)を車両前部空間Sに導く開口1402が設けられている。
アッパーフレーム34は、上下に延在する本体板部36と、本体板部36の上端から車幅方向外側に延在する上横板部38と、を備えている。
図1~図3に示すように、エアクリーナ22の空気取り入れ口2202は、右側のアッパーフレーム34の本体板部36に設けられている。
したがって、空気取り入れ口2202は、アッパーフレーム34とフェンダーパネル16との間に配置されている。
フランジ部1602は、本体板部36に取り付けられたブラケット40により、アッパーフレーム34の上面(後述する上横板部38)に対して上方に隙間S2を有して支持されている。
図7に示すように、フェンダーガーニッシュ42は合成樹脂で形成される。空気取り入れ口2202は、フェンダーガーニッシュ42の車両前方の箇所である前部42Aの下方、すなわち、フェンダー空間S3内の前部42Aと隣り合う箇所に位置している。
図3、図5、図6に示すように、フェンダーガーニッシュ42は取付部44と遮蔽部45と支持部50とを備えている。
取り付け具挿通孔4402は、上方に至るにつれて車両前方に変位するように傾斜した長孔4402Aで形成されている。
下板部46は、取付部44の上部から車幅方向内側に突出している。
縦板部47は、横板部46の車幅方向内側の端部から上方に延在している。
上板部48は、縦板部47の上端から車幅方向外側に延在している。また、上板部48は、フェンダーガーニッシュ42の前部42Aにおいて、車幅方向外側に至るにつれて次第に上方に変位するように傾斜している。
言い換えると、縦板部47は、隙間S2と対向して上下方向に延びる。下板部46は、縦板部47の下端から車幅方向外側に延びて取付部44に連結される。上板部48は、縦板部47の上端から車幅方向外側に延びて、後述する支持部50に連結されている。
上記構成により、フェンダーガーニッシュ42は、車幅方向かつ車両上下方向に延びる仮想平面での断面形状が車幅方向外側に開口する略U字状に形成されている。
言い換えると、支持部50は、フェンダーパネル16のフランジ部1602の上方に所定の間隔を設けて配設されてフード18を支持する。
なお、図5に示すように、フェンダーガーニッシュ42の車両後方の箇所である後部42Bでは、下板部46の突出量が前部42Aに比べ小さく、縦板部47が前部42Aに比べ車幅方向外側に位置している。また、上板部48は傾斜していない。
フェンダーガーニッシュ42の前部42Aと後部42Bとの境界では、縦板部47が後方に至るにつれて車幅方向外側に傾斜した縦板傾斜部4702となっており、前部42Aと後部42Bとを連結している。
脚部5002は、下方に至るにつれて車両後方に変位するよう傾斜して形成されている。
すなわち、図5、図6、図7に示すように、フェンダーガーニッシュ42の車両前方側端部4202は、フェンダーガーニッシュ42とアッパーフレーム34とで囲まれる空間S1に車両前方側から空気を取り込み可能となるように車両前方に開放されている。
また、フェンダーガーニッシュ42とアッパーフレーム34との間の空間S1は、車両前方側(前部42A)の大きさが車両後方側(後部42B)の大きさに比べ大きくなるように形成されている。本実施形態では、後部42Bの縦板部47が前部42Aの縦板部47よりも車幅方向外側に位置している、すなわち、アッパーフレーム34に接近していることによって、空間S1を小さくしている。
また、フロントグリル14の開口1402から車両前部空間Sに導入された空気Aの一部は、フェンダーガーニッシュ42の開口部56から空間S1に導かれ、フランジ部1602とアッパーフレーム34の上横板部38の間の隙間S2を通り、エアクリーナ22の空気取り入れ口2202に吸入される。
したがって、エンジン20の燃焼効率が確保され、燃費が向上する。
また、フェンダーガーニッシュ42の支持部50が、フェンダーパネル16のフランジ部1602よりも上方でフード18を支持する。このため、フード18の上方から斜め後方に向かって例えば歩行者の頭部が衝突した際、フード18はフェンダーガーニッシュ42を変形させながら下方に変形する。この結果、フード18がフェンダーパネル16に当接する前に衝突エネルギーを吸収することができ、衝撃吸収性能が向上して歩行者保護性能が向上する。
このとき、上板部48を車幅方向外側に向かって次第に上方へ変位するよう傾斜させることによって、フード18の変形ストロークが更に確保され、衝撃吸収性能が向上する。
言い換えると、フェンダーガーニッシュ42の車両前方箇所における空間(フェンダーガーニッシュ42とアッパーフレーム34とで囲まれる空間S1)を車幅方向および上下方向を通る仮想平面で切断した断面形状は、フェンダーガーニッシュ42の車両後方箇所における空間を車幅方向および上下方向を通る仮想平面で切断した断面形状よりも大きく形成されている。空気取り入れ口2202は、フェンダーガーニッシュ42の車両前方箇所の下方に位置している。
したがって、走行時、フロントグリル14の開口1402から車両前部空間Sに導かれた温度の低い空気が、積極的にフェンダー空間S3に導かれる。この結果、温度の低い空気が、空気取り入れ口2202からエアクリーナ22に吸い込まれ、エンジン20の燃焼効率が確保されて、燃費が向上する。
フェンダーガーニッシュ42の縦板部47は、車両後方に至るにつれて車幅方向外側に傾斜する縦板傾斜部4702を有する。縦板傾斜部4702により、空間S1は車両後方に至るにつれて小さくなる。このため、温度の低い空気を空気取り入れ口2202に導く上で有利となる。
