Abstract

PROBLEM TO BE SOLVED: To stabilize traveling air flowing under the floor of a vehicle.SOLUTION: In a vehicle to which a vehicle front part structure is applied, a streamline part 28 of a vertical wall 26 of an air deflector 20 is disposed with a gradient to the vehicle rear side as it goes toward the inside in the vehicle width direction as viewed from the lower side of the vehicle. Thus, the traveling air striking on the vertical wall 26 is routed to the vehicle rear side of the streamline part 28 to stride over the end of the inside in the vehicle width direction of the vertical wall 26 (see an arrow D shown in Fig. 1). The lower end part of the streamline part 28 is inclined to the rear side of the vehicle in a side view. Thus, the traveling air striking on the vertical wall 26 is routed to the rear side of the vehicle of the streamline part 28 to stride over the lower end part of the streamline part 28 (see an arrow E shown in Fig. 1). Whereupon, at the rear side of the vehicle, a vortex, the axial direction of which is the longitudinal direction of the vehicle, is generated at the rear side of the vehicle of the streamline part 28. Therefore, the air under the floor of the vehicle is streamlined to the rear side of the vehicle by the aerodynamic force of the vortex, so that the flow of the air under the floor of the vehicle can be stabilized.

Moreover, the tire deflector has a main body portion, and the main body portion is formed in a plate shape and extends from the attachment portion to the vehicle lower side. Thereby, when a motor vehicle drive | works, a driving | running wind hits a main-body part, and can reduce the quantity of the driving | running | working wind introduce | transduced in a tire house.

特開２００７−１６８６２０号公報JP 2007-168620 A

しかしながら、このタイヤデフレクタでは、タイヤデフレクタの本体部に当たった走行風が、車両の床下における空気の流れを安定させることについては考慮されていない。   However, in this tire deflector, it is not considered that the traveling wind that hits the main body of the tire deflector stabilizes the air flow under the floor of the vehicle.

本発明は、上記事実を考慮し、車両の床下を流れる走行風を安定させることができる車両前部構造を提供することを目的とする。   In view of the above facts, an object of the present invention is to provide a vehicle front structure that can stabilize the traveling wind flowing under the floor of the vehicle.

請求項１に記載の車両前部構造は、前輪の車両前側で車両幅方向に延在されると共に、車両の下部に取付けられる取付部と前記取付部から車両下側へ延びる縦壁とを含んで構成されたスパッツと、前記縦壁の車両幅方向内側部分を構成し、車両下方から見て車両幅方向内側へ向かうに従い車両後側へ傾斜して配置されると共に、側面視で車両下側へ向かうに従い車両後側へ傾斜して配置された整流部と、を備えている。   The vehicle front portion structure according to claim 1 includes a mounting portion attached to a lower portion of the vehicle and a vertical wall extending from the mounting portion to the vehicle lower side while extending in the vehicle width direction on the vehicle front side of the front wheel. The spats are configured to form an inner portion of the vertical wall in the vehicle width direction, and are inclined to the vehicle rear side toward the vehicle width direction inward when viewed from the lower side of the vehicle. And a rectifying unit arranged to be inclined toward the rear side of the vehicle as it goes to.

請求項１に記載の車両前部構造では、前輪の車両前側にスパッツが設けられており、スパッツは車両幅方向に延在されている。また、スパッツは、車両の下部に取付けられる取付部を有しており、取付部から縦壁が車両下側へ延びている。このため、車両が走行する際に走行風が縦壁に当たることによって、前輪に直接当たる走行風の量を減らすことができる。また、この際には、走行風が縦壁に当たるため、縦壁の車両前側の領域における圧力が、縦壁の車両後側の領域における圧力に比して大きくなる。換言すると、縦壁の車両後側の領域が負圧領域になる。   In the vehicle front structure according to the first aspect, spats are provided on the front side of the front wheels, and the spats extend in the vehicle width direction. Further, the spats have an attachment portion that is attached to the lower portion of the vehicle, and a vertical wall extends downward from the attachment portion. For this reason, when the vehicle travels, the amount of travel wind that directly hits the front wheels can be reduced by the travel wind hitting the vertical wall. At this time, since the traveling wind hits the vertical wall, the pressure in the vehicle front side region of the vertical wall becomes larger than the pressure in the vehicle rear side region of the vertical wall. In other words, the area on the vehicle rear side of the vertical wall becomes the negative pressure area.

ここで、縦壁の車両内側部分が整流部とされており、整流部は、車両下方から見て車両幅方向内側へ向かうに従い車両後側へ傾斜して配置されている。これにより、縦壁に当たった走行風が車両下方から見て縦壁（整流部）に沿って車両幅方向内側へ案内される。そして、縦壁の車両後側の領域が負圧領域とされているため、縦壁の車両幅方向内側の端部に案内された走行風が、車両下方から見て、この端部を跨ぐように整流部（縦壁）の車両後側（負圧領域側）へ回り込む。   Here, the vehicle inner side portion of the vertical wall is a rectifying unit, and the rectifying unit is arranged to be inclined toward the vehicle rear side as it goes inward in the vehicle width direction when viewed from the lower side of the vehicle. As a result, the traveling wind hitting the vertical wall is guided inward in the vehicle width direction along the vertical wall (rectifying portion) when viewed from below the vehicle. And since the area | region of the vehicle rear side of a vertical wall is made into the negative pressure area, the driving | running | working wind guided to the edge part of the vehicle width direction inside of a vertical wall seems to straddle this edge part seeing from a vehicle lower part. To the vehicle rear side (negative pressure region side) of the rectification unit (vertical wall).

また、整流部は、側面視で車両下側へ向かうに従い車両後側へ傾斜して配置されている。これにより、縦壁に当たった走行風が側面視で整流部に沿って車両下側にも案内される。そして、縦壁の車両後側の領域が負圧領域とされているため、整流部の下端部に案内された走行風が、側面視で、整流部の下端部を跨ぐように整流部（縦壁）の車両後側（負圧領域側）へ回り込む。   Moreover, the rectification | straightening part is inclined and arrange | positioned at the vehicle rear side as it goes to the vehicle lower side by side view. As a result, the traveling wind hitting the vertical wall is guided to the lower side of the vehicle along the rectifying unit in a side view. And since the area | region of the vehicle rear side of a vertical wall is made into the negative pressure area | region, the driving | running | working wind guided to the lower end part of the rectification | straightening part is a rectification | straightening part (vertical | vertical) so that it may straddle the lower end part of a rectification | straightening part in side view. Go to the rear side of the vehicle (wall side) (negative pressure area side).

そうすると、車両下方から見て縦壁の車両幅方向内側の端部を跨いで整流部（縦壁）の車両後側へ回り込む走行風と、側面視で整流部の下端部を跨いで整流部（縦壁）の車両後側へ回り込む走行風と、によって、車両前後方向を軸方向とした渦流が整流部の車両後側に生じる。したがって、この渦流（の空気力）によって車両の床下の空気が車両後側へ整流されるため、車両の床下の空気の流れを安定させることができる。   Then, when viewed from the bottom of the vehicle, the running wind that goes around the vehicle width direction inner end of the vertical wall to the vehicle rear side of the rectifying unit (vertical wall), and the rectifying unit (crossing the lower end of the rectifying unit in side view) Due to the traveling wind that circulates to the vehicle rear side of the vertical wall), a vortex with the vehicle longitudinal direction as the axial direction is generated on the vehicle rear side of the rectifying unit. Therefore, the air under the floor of the vehicle is rectified to the rear side of the vehicle by the eddy current (the aerodynamic force), and the flow of air under the floor of the vehicle can be stabilized.

請求項２に記載の車両前部構造は、請求項１に記載の車両前部構造において、前記整流部は、車両下方から見て車両幅方向内側へ向かうに従い車両後側へ湾曲して傾斜されると共に、側面視で車両下側へ向かうに従い車両後側へ湾曲して傾斜されている。   The vehicle front part structure according to claim 2 is the vehicle front part structure according to claim 1, wherein the rectifying part is curved and inclined toward the vehicle rear side as it goes inward in the vehicle width direction when viewed from the vehicle lower side. In addition, it is curved and inclined toward the rear side of the vehicle as it goes to the lower side of the vehicle in a side view.

請求項２に記載の車両前部構造では、整流部が、車両下方から見て車両幅方向内側へ向かうに従い車両後側へ湾曲されているため、縦壁に当たった走行風が整流部に沿って車両幅方向内側へスムースに案内される。また、整流部が、側面視で車両下側へ向かうに従い車両後側へ湾曲されているため、縦壁に当たった走行風が整流部に沿って車両下側へスムースに案内される。これにより、整流部の車両後側に渦流を効率よく発生させることができる。   In the vehicle front structure according to claim 2, since the rectification portion is curved toward the vehicle rear side as it goes inward in the vehicle width direction when viewed from the lower side of the vehicle, traveling wind hitting the vertical wall follows the rectification portion. Thus, the vehicle is smoothly guided inward in the vehicle width direction. Further, since the rectifying unit is curved toward the rear side of the vehicle as viewed from the side as viewed from the side, the traveling wind hitting the vertical wall is smoothly guided to the lower side of the vehicle along the rectifying unit. Thereby, a vortex | eddy_current can be efficiently generated on the vehicle rear side of a rectification | straightening part.

請求項１に記載の車両前部構造によれば、車両の床下の空気の流れを安定させることができる。   According to the vehicle front structure according to the first aspect, the flow of air under the floor of the vehicle can be stabilized.

請求項２に記載の車両前部構造によれば、整流部の車両後側に渦流を効率よく発生させることができる。   According to the vehicle front structure according to the second aspect, it is possible to efficiently generate a vortex on the vehicle rear side of the rectifying unit.

In the drawings, the front side of the vehicle is indicated by an arrow FR, the right side of the vehicle (one side in the vehicle width direction) is indicated by an arrow RH, and the upper side of the vehicle is indicated by an arrow UP.

この図に示されるように、車両１０は、ホイールハウス１２に沿って配置されたフェンダライナ１４を備えている。このフェンダライナ１４は、側面視で車両下方へ開放された略アーチ形板状に形成されており、フェンダライナ１４の前端部が車両前側へ屈曲されている。そして、フェンダライナ１４の径方向内側には、前輪１６が配置されており、フェンダライナ１４は、前輪１６の上部を車両上側から覆っている。   As shown in this figure, the vehicle 10 includes a fender liner 14 disposed along the wheel house 12. The fender liner 14 is formed in a substantially arched plate shape opened to the vehicle lower side in a side view, and the front end portion of the fender liner 14 is bent toward the vehicle front side. And the front wheel 16 is arrange | positioned inside the radial direction of the fender liner 14, and the fender liner 14 has covered the upper part of the front wheel 16 from the vehicle upper side.

また、前輪１６の車両前側には、「スパッツ」としてのエアスパッツ２０がそれぞれ設けられており、エアスパッツ２０は、フェンダライナ１４の前端部に取付けられている（図４及び図５参照）。以下、このエアスパッツ２０について、図１〜図５に基づいて説明する。なお、エアスパッツ２０は、車両幅方向において左右対称に構成されているため、車両右側に配置されたエアスパッツ２０について説明し、車両左側に配置されたエアスパッツ２０についての説明は省略する。   Further, air spats 20 as “spats” are respectively provided on the front side of the front wheels 16, and the air spats 20 are attached to the front end portion of the fender liner 14 (see FIGS. 4 and 5). Hereinafter, the air spats 20 will be described with reference to FIGS. In addition, since the air spats 20 are symmetrically configured in the vehicle width direction, the air spats 20 disposed on the right side of the vehicle will be described, and the description of the air spats 20 disposed on the left side of the vehicle will be omitted.

これらの図に示されるように、エアスパッツ２０は、樹脂により製作されると共に、取付部２２と縦壁２６とを含んで構成されている。取付部２２は、車両上方から見て、略長尺板状に形成されて、板厚方向を車両上下方向にして車両幅方向に延びている。具体的には、取付部２２の車両幅方向外側の部分（図１に示される矢印Ａ及び矢印Ｂの範囲の部分）が、車両上方から見て車両前側へ凸となるように僅かに湾曲されており、取付部２２の車両幅方向内側の部分（図１に示される矢印Ｃの範囲の部分）が、車両上方から見て車両幅方向内側へ向かうに従って車両後側へ直線状に傾斜されている。   As shown in these drawings, the air spats 20 are made of resin, and include an attachment portion 22 and a vertical wall 26. The attachment portion 22 is formed in a substantially long plate shape as viewed from above the vehicle, and extends in the vehicle width direction with the plate thickness direction being the vehicle vertical direction. Specifically, the outer portion of the mounting portion 22 in the vehicle width direction (the portion in the range of the arrow A and the arrow B shown in FIG. 1) is slightly curved so as to protrude toward the front of the vehicle when viewed from above the vehicle. The portion of the mounting portion 22 on the inner side in the vehicle width direction (the portion in the range of the arrow C shown in FIG. 1) is linearly inclined toward the vehicle rear side as it goes inward in the vehicle width direction as viewed from above the vehicle. Yes.

また、取付部２２には、複数（本実施の形態では３つ）の取付孔２４が形成されており、取付孔２４は、略円形状に形成されて、車両上下方向に貫通されている。図４に示されるように、この取付孔２４には、グロメット１８等の締結部材が挿入されており、このグロメット１８等の締結部材によって取付部２２（エアスパッツ２０）がフェンダライナ１４の前端部に取付けられている。   A plurality of (three in this embodiment) attachment holes 24 are formed in the attachment portion 22, and the attachment holes 24 are formed in a substantially circular shape and penetrate in the vehicle vertical direction. As shown in FIG. 4, a fastening member such as a grommet 18 is inserted into the mounting hole 24, and the mounting portion 22 (air spats 20) is inserted into the front end portion of the fender liner 14 by the fastening member such as the grommet 18. Installed on.

図１〜図３に示されるように、縦壁２６は、取付部２２の後端部に一体に形成されると共に、当該後端部から車両下側へ延びている。これにより、縦壁２６の車両幅方向内側の部分（図１に示される矢印Ｃの範囲の部分）が、車両上方から見て車両幅方向内側へ向かうに従って車両後側へ直線状に傾斜されており、この部分が整流部２８とされている。そして、車両幅方向に沿った基準線Ｈ１に対する整流部２８の成す角度が傾斜角θ１（図１参照）とされている。   As shown in FIGS. 1 to 3, the vertical wall 26 is formed integrally with the rear end portion of the attachment portion 22 and extends from the rear end portion to the vehicle lower side. As a result, the portion of the vertical wall 26 on the inner side in the vehicle width direction (the portion in the range of the arrow C shown in FIG. 1) is linearly inclined toward the vehicle rear side toward the inner side in the vehicle width direction as viewed from above the vehicle. This portion is the rectifying unit 28. The angle formed by the rectification unit 28 with respect to the reference line H1 along the vehicle width direction is the inclination angle θ1 (see FIG. 1).

また、図３に示されるように、整流部２８における車両下側の部分は、側面視で車両前斜め下方へ凸となる略円弧状に湾曲されており、この湾曲された部分の曲率半径は一定に設定されている。これにより、整流部２８の下端部は、側面視で、車両上下方向に対して当該下端部に接する接線に沿って車両後側に傾斜して配置されており、車両上下方向に沿った基準線Ｈ２に対する整流部２８における下端部の成す角度が傾斜角θ２とされている。   Further, as shown in FIG. 3, the vehicle lower side portion of the rectifying unit 28 is curved in a substantially arc shape that protrudes obliquely downward in front of the vehicle in a side view, and the curvature radius of the curved portion is It is set constant. Accordingly, the lower end portion of the rectifying unit 28 is disposed to be inclined toward the rear side of the vehicle along a tangent line in contact with the lower end portion with respect to the vehicle vertical direction in a side view, and a reference line along the vehicle vertical direction. The angle formed by the lower end of the rectifying unit 28 with respect to H2 is the inclination angle θ2.

一方、縦壁２６の整流部２８以外の部分（図１に示される矢印Ａ及び矢印Ｂの範囲の部分）は、一般部３０とされており、一般部３０は車両上方から見て車両前側へ凸となるように僅かに湾曲されている。この一般部３０における車両幅方向外側の部分（図１に示される矢印Ａの範囲の部分）では、図４に示されるように、取付部２２の後端部から一般部３０（縦壁２６）が直線状に車両下側へ延びている。また、一般部３０における車両幅方向内側の部分（図１に示される矢印Ｂの範囲の部分）では、図５に示されるように、一般部３０（縦壁２６）の車両下側の部分が、車両前斜め下方へ凸となる略円弧状に湾曲されており、この部分の曲率半径が、車両幅方向内側へ向かうに従って小さくなるように設定されている。すなわち、一般部３０における車両幅方向内側の部分（図１に示される矢印Ｂの範囲の部分）では、車両幅方向内側（整流部２８側）へ向かうに従って基準線Ｈ２に対する傾斜角θ２が徐々に大きくなるように設定されている。これにより、一般部３０と整流部２８とが段差がないように滑らかに接続されている。   On the other hand, a portion of the vertical wall 26 other than the rectifying portion 28 (a portion in the range of arrows A and B shown in FIG. 1) is a general portion 30, and the general portion 30 is directed to the front side of the vehicle as viewed from above the vehicle. It is slightly curved to be convex. In the vehicle width direction outer portion of this general portion 30 (the portion in the range of arrow A shown in FIG. 1), as shown in FIG. 4, the general portion 30 (vertical wall 26) from the rear end portion of the attachment portion 22. Extends downward in the vehicle. In addition, in the vehicle width direction inner portion of the general portion 30 (the portion in the range of arrow B shown in FIG. 1), as shown in FIG. 5, the vehicle lower portion of the general portion 30 (vertical wall 26) is It is curved in a substantially arc shape that protrudes obliquely downward in front of the vehicle, and the radius of curvature of this portion is set so as to decrease toward the inner side in the vehicle width direction. That is, in the vehicle width direction inner portion of the general portion 30 (the portion in the range of the arrow B shown in FIG. 1), the inclination angle θ2 with respect to the reference line H2 gradually increases toward the vehicle width direction inner side (rectifier portion 28 side). It is set to be large. Thereby, the general part 30 and the rectification | straightening part 28 are connected smoothly so that there may be no level | step difference.

そして、図６に示されるように、車両下方から見て、縦壁２６の一般部３０が前輪１６の車両前側に配置されると共に、縦壁２６の整流部２８は前輪１６よりも車両内側に配置されるように構成されている。   As shown in FIG. 6, when viewed from the lower side of the vehicle, the general portion 30 of the vertical wall 26 is disposed on the vehicle front side of the front wheel 16, and the rectifying portion 28 of the vertical wall 26 is on the vehicle inner side than the front wheel 16. It is configured to be arranged.

次に、本実施の形態の作用及び効果について説明する。   Next, the operation and effect of the present embodiment will be described.

上記のように構成された車両前部構造Ｓが適用された車両１０が走行すると、走行風の一部が、エアスパッツ２０の縦壁２６に当たる。これにより、縦壁２６の車両前側の領域における圧力が、縦壁２６の車両後側の領域における圧力に比して大きくなる。換言すると、縦壁２６の車両後側の領域が負圧領域になる。   When the vehicle 10 to which the vehicle front structure S constructed as described above is applied travels, a part of the traveling wind hits the vertical wall 26 of the air spats 20. Thereby, the pressure in the area | region of the vehicle front side of the vertical wall 26 becomes large compared with the pressure in the area | region of the vehicle rear side of the vertical wall 26. FIG. In other words, the region on the vehicle rear side of the vertical wall 26 becomes a negative pressure region.

ここで、縦壁２６の車両幅方向内側部分を構成する整流部２８は、車両下方（上方）から見て、車両幅方向内側へ向かうに従い車両後側へ傾斜して配置されている。これにより、縦壁２６に当たった走行風が、車両下方（上方）から見て、整流部２８に沿って車両幅方向内側へ案内される。そして、縦壁２６の車両幅方向内側の端部に案内された走行風は、車両下方（上方）から見て、当該端部を跨ぐように整流部２８（縦壁２６）の車両後側（負圧領域側）へ回り込む（図１の矢印Ｄ参照）。   Here, the rectification part 28 which comprises the vehicle width direction inner side part of the vertical wall 26 is arrange | positioned so that it may incline to the vehicle rear side as it goes to a vehicle width direction inner side seeing from the vehicle lower side (upper side). As a result, the traveling wind hitting the vertical wall 26 is guided inward in the vehicle width direction along the rectifying unit 28 when viewed from the lower side (upper side) of the vehicle. And the driving | running | working wind guided to the edge part of the vehicle width direction inner side of the vertical wall 26 sees from the vehicle downward (upper side), and the vehicle rear side (vertical wall 26) of the rectification | straightening part 28 (vertical wall 26) is straddle | crossed the said edge part. It goes around to the negative pressure region side (see arrow D in FIG. 1).

また、整流部２８の車両下側部分は、側面視で車両前斜め下方へ凸となるように湾曲されると共に、基準線Ｈ２に対して傾斜角θ２に傾斜されている。これにより、縦壁２６に当たった走行風が、側面視で整流部２８に沿って車両下側にも案内される。そして、整流部２８の下端部に案内された走行風は、側面視で、整流部２８の下端部を跨ぐように整流部２８（縦壁２６）の車両後側（負圧領域側）へ回り込む（図１及び図３の矢印Ｅ参照）。   Further, the vehicle lower side portion of the rectifying unit 28 is curved so as to protrude obliquely downward in front of the vehicle in a side view, and is inclined at an inclination angle θ2 with respect to the reference line H2. Thereby, the traveling wind hitting the vertical wall 26 is guided to the vehicle lower side along the rectifying unit 28 in a side view. And the driving | running | working wind guided to the lower end part of the rectification | straightening part 28 turns into the vehicle rear side (negative pressure area | region side) of the rectification | straightening part 28 (vertical wall 26) so that the lower end part of the rectification | straightening part 28 may be straddle | crossed by side view. (See arrow E in FIGS. 1 and 3).

そうすると、車両下方（上方）から見て縦壁２６の車両幅方向内側の端部を跨いで整流部２８（縦壁２６）の車両後側（負圧領域側）へ回り込む走行風と、側面視で整流部２８の下端部を跨いで整流部２８の車両後側へ回り込む走行風と、によって、車両前後方向を軸方向とした渦流Ｆが整流部２８の車両後側に生じる（図２及び図６の矢印Ｆ参照）。したがって、この渦流Ｆ（の空気力）によって車両１０の床下の空気が車両後側へ整流されるため（図６の矢印Ｇ参照）、車両１０の床下の空気の流れを安定させることができる。   Then, as viewed from the lower side (upper side) of the vehicle, traveling wind that wraps around the vehicle width direction inner side end of the vertical wall 26 to the vehicle rear side (negative pressure region side) of the rectifying unit 28 (vertical wall 26), and side view Thus, eddy current F having the vehicle longitudinal direction as an axial direction is generated on the vehicle rear side of the rectification unit 28 by the traveling wind that crosses the lower end portion of the rectification unit 28 and turns to the vehicle rear side of the rectification unit 28 (FIGS. 2 and FIG. 2). 6 (see arrow F). Therefore, the air under the floor of the vehicle 10 is rectified to the rear side of the vehicle by the vortex flow F (the aerodynamic force thereof) (see the arrow G in FIG. 6), so that the flow of the air under the floor of the vehicle 10 can be stabilized.

また、上述したように、エアスパッツ２０の縦壁２６に整流部２８を形成することによって渦流Ｆが縦壁２６の車両後側に生じて、車両１０の床下の空気の流れが当該渦流Ｆによって安定する。これにより、部品点数を増加させることなく簡易な構成で車両１０の床下における空気の流れを安定させることができる。しかも、各種の車両に対応して、車両幅方向に沿った基準線Ｈ１に対する整流部２８の傾斜角θ１及び車両上下方向に沿った基準線Ｈ２に対する整流部２８の傾斜角θ２を適宜設定することで、各種車両において、車両の床下における空気の流れを安定させることができる。   Further, as described above, by forming the rectifying portion 28 on the vertical wall 26 of the air spats 20, the vortex F is generated on the vehicle rear side of the vertical wall 26, and the air flow under the floor of the vehicle 10 is caused by the vortex F. Stabilize. Thereby, the flow of air under the floor of the vehicle 10 can be stabilized with a simple configuration without increasing the number of parts. Moreover, the inclination angle θ1 of the rectification unit 28 with respect to the reference line H1 along the vehicle width direction and the inclination angle θ2 of the rectification unit 28 with respect to the reference line H2 along the vehicle vertical direction are set as appropriate for various vehicles. Thus, in various vehicles, the air flow under the floor of the vehicle can be stabilized.

さらに、縦壁２６の一般部３０は、車両上方から見て、車両前側へ凸となるように湾曲されている。これにより、縦壁２６の一般部３０に当たった走行風を縦壁２６の整流部２８へ向けてスムースに案内させることができる。   Furthermore, the general part 30 of the vertical wall 26 is curved so as to protrude toward the front side of the vehicle when viewed from above the vehicle. Thereby, the traveling wind which hits the general part 30 of the vertical wall 26 can be smoothly guided toward the rectifying part 28 of the vertical wall 26.

また、一般部３０における車両幅方向内側の部分（図１に示される矢印Ｂの範囲の部分）では、基準線Ｈ２に対する傾斜角θ２が車両幅方向内側へ向かうに従って徐々に大きくなるように設定されており、一般部３０と整流部２８とが段差がないように滑らかに接続されている。これにより、縦壁２６の一般部３０に当たった走行風を、縦壁２６の整流部２８へ向けて一層スムースに案内させることができる。   Further, in the vehicle width direction inner portion of the general portion 30 (the portion in the range of the arrow B shown in FIG. 1), the inclination angle θ2 with respect to the reference line H2 is set to gradually increase toward the vehicle width direction inner side. The general portion 30 and the rectifying portion 28 are smoothly connected so that there is no step. Thereby, the traveling wind hitting the general part 30 of the vertical wall 26 can be guided more smoothly toward the rectifying part 28 of the vertical wall 26.

なお、本実施の形態では、縦壁２６の整流部２８が、車両上方から見て車両内側へ向かうに従い車両後側へ直線状に傾斜されている。これに替えて、縦壁２６の整流部２８を車両上方から見て湾曲（曲線状）して傾斜させてもよい。これにより、縦壁２６に当たった走行風が車両幅方向内側へスムースに案内されるため、渦流Ｆを効率よく発生させることができる。   In the present embodiment, the rectifying portion 28 of the vertical wall 26 is linearly inclined toward the vehicle rear side as it goes toward the vehicle inner side as viewed from above the vehicle. Instead of this, the straightening portion 28 of the vertical wall 26 may be curved (curved) and inclined when viewed from above the vehicle. As a result, the traveling wind that hits the vertical wall 26 is smoothly guided inward in the vehicle width direction, so that the vortex F can be efficiently generated.

また、本実施の形態では、縦壁２６の整流部２８が、側面視で車両下側へ向かうに従い車両後側へ湾曲（曲線状）して傾斜されている。これに替えて、縦壁２６の整流部２８を、側面視で車両下側へ向かうに従い車両後側へ直線状に傾斜させてもよい。例えば、図７（Ａ)に示されるように、整流部２８の車両上下方向中間部と下端部との間の部分を直線状に傾斜させてもよいし、図７（Ｂ)に示されるように、整流部２８の上端部と下端部との間の部分を直線状に傾斜させてもよい。   Moreover, in this Embodiment, the rectification | straightening part 28 of the vertical wall 26 is curving (curve-shaped) and inclining to the vehicle rear side as it goes to the vehicle lower side by side view. Instead of this, the straightening portion 28 of the vertical wall 26 may be inclined linearly toward the rear side of the vehicle as it goes to the lower side of the vehicle in a side view. For example, as shown in FIG. 7A, the portion between the vehicle vertical direction middle portion and the lower end portion of the rectifying portion 28 may be linearly inclined, or as shown in FIG. 7B. In addition, the portion between the upper end portion and the lower end portion of the rectifying unit 28 may be inclined linearly.

さらに、本実施の形態では、縦壁２６の一般部３０の車両幅方向内側部分（図１の矢印Ｂの範囲の部分）において、車両下側部分の曲率半径が車両内側へ向かうに従い徐々に小さく設定されており、縦壁２６の整流部２８における車両下側部分の曲率半径が一定に設定されている。これに替えて、一般部３０の車両幅方向内側部分及び整流部２８の範囲において、縦壁２６の車両下側部分の曲率半径を車両内側へ向かうに従い徐々に小さく設定してもよい。   Further, in the present embodiment, the curvature radius of the vehicle lower side portion of the general portion 30 of the vertical wall 26 in the vehicle width direction inner portion (the portion in the range of the arrow B in FIG. 1) gradually decreases as it goes toward the vehicle inner side. The radius of curvature of the lower portion of the vehicle in the straightening portion 28 of the vertical wall 26 is set to be constant. Instead, in the range of the vehicle width direction inner portion of the general portion 30 and the rectifying portion 28, the radius of curvature of the vehicle lower side portion of the vertical wall 26 may be set gradually smaller toward the vehicle inner side.

また、本実施の形態では、車両上方から見て、縦壁２６の一般部３０が車両前側に凸になるように湾曲して配置されている。これに替えて、車両上方から見て、一般部３０を車両幅方向内側へ向かうに従い車両後側へ若干傾斜するように直線状に配置してもよい。また、車両上方から見て、一般部３０を車両幅方向に直線状に延びるように設定してもよい。   Moreover, in this Embodiment, seeing from the vehicle upper direction, the general part 30 of the vertical wall 26 is curved and arrange | positioned so that it may protrude in the vehicle front side. Alternatively, the general portion 30 may be arranged in a straight line so as to slightly incline toward the rear of the vehicle as it goes inward in the vehicle width direction when viewed from above the vehicle. Further, when viewed from above the vehicle, the general portion 30 may be set to extend linearly in the vehicle width direction.
