As shown in a sectional view in FIG. 4, the LED 27 as a light source unit that emits light rearward, its substrate 28 (that is, the LED substrate), and the lower surface portion of the rear spoiler 25 are configured, and the LED 27 is supported via the substrate 28. And a housing 29 as a base portion and an outer lens 30 as a red transparent body portion constituting the upper surface portion and the rear surface portion of the rear spoiler 25, and is configured to radiate light of the LED 27 rearward through the outer lens 30.

ここで、上述のLED27は図8に示すように、その複数個が基板28に一列状に設けられており、この基板28を介してリヤスポイラ25内に収容されている。   Here, as shown in FIG. 8, a plurality of the LEDs 27 are provided in a row on the substrate 28, and are accommodated in the rear spoiler 25 via the substrate 28.

図7に分解斜視図で示すように、リヤスポイラ25のハウジング29はリヤハッチ3のアウタパネル15と一体成形されている。上述の各LED27に電源を供給するハーネス31は図7に示すように、ハウジング29に開口形成された孔部32を介してリヤハッチ3側へ配設されて、この孔部32はハーネスグロメット33で閉塞される。また、アウタレンズ30は複数のビス等の取付け部材34を用いてハウジング29乃至リヤハッチ中央凹部22の段差部24に取付けられる。   As shown in an exploded perspective view in FIG. 7, the housing 29 of the rear spoiler 25 is integrally formed with the outer panel 15 of the rear hatch 3. As shown in FIG. 7, the harness 31 for supplying power to each LED 27 is disposed on the rear hatch 3 side through a hole 32 formed in the housing 29. The hole 32 is a harness grommet 33. Blocked. The outer lens 30 is attached to the step portion 24 of the housing 29 or the rear hatch central recess 22 using a plurality of attachment members 34 such as screws.

ここで、上述のハウジング29をリヤハッチ3のアウタパネル15と一体形成する構造に代えて、各要素27〜31から成るリヤスポイラ25をサブアセンブリし、このリヤスポイラ25を、リヤハッチ3におけるリヤハッチ中央凹部22の段差部24に後付けする構造を採用してもよい。   Here, instead of the structure in which the housing 29 described above is integrally formed with the outer panel 15 of the rear hatch 3, a rear spoiler 25 composed of the elements 27 to 31 is sub-assembled, and the rear spoiler 25 is used as a step of the rear hatch central recess 22 in the rear hatch 3. A structure retrofitted to the portion 24 may be employed.

なお、図中、矢印Fは車両前方を示し、矢印Rは車両後方を示すものである。また、図3、図4において仮想線Zは後席乗員の頭部を概略的に示すものである。さらに、図4においては本実施例の構造と、従来例の構造とを対比する目的で、従来構造のルーフパネルβ1と、従来構造の雨樋部の縦壁部において前方に膨出する凹形状β2と、従来構造のリヤハッチβ3とをそれぞれ仮想線にて併記している。   In the figure, arrow F indicates the front of the vehicle, and arrow R indicates the rear of the vehicle. 3 and 4, the imaginary line Z schematically shows the head of the rear passenger. Further, in FIG. 4, for the purpose of comparing the structure of the present embodiment with the structure of the conventional example, a concave shape that bulges forward in the vertical wall portion of the roof panel β1 of the conventional structure and the rain gutter portion of the conventional structure. β2 and the rear hatch β3 of the conventional structure are shown together with phantom lines.

このように構成した車体後部構造において、車両の走行時には図9に矢印dで示すように、ルーフの後面視ラウンド形状に起因して空気流がルーフ中央部に集まり、ルーフ後端部を通過した車幅方向の中心流が車幅方向外側に引き寄せられ、ルーフ後端部の平面視円弧形状に起因して、両ルーフサイド後方には一般に発生する内回りの一対の渦(剥離流)(矢印e参照)が強くなり、この渦が外向きに指向するが、本実施例ではルーフ後方中央凹部4およびリヤハッチ中央凹部22により中心流cを強くすることができるので、上述の両側への吸い寄せに抗して、上記渦(矢印e参照)を低減して、空気抗力係数Cdの低減を図ることができると推考される。   In the rear structure of the vehicle body configured as described above, as shown by an arrow d in FIG. 9, when the vehicle travels, air flow gathers at the center of the roof due to the round shape of the rear view of the roof and passes through the rear end of the roof. A central flow in the vehicle width direction is attracted to the outside in the vehicle width direction, and due to the arc shape of the rear end of the roof in a plan view, a pair of inward vortices (separation flow) generally generated behind both roof sides (arrow e) In this embodiment, the central flow c can be strengthened by the roof rear center concave portion 4 and the rear hatch central concave portion 22, so that the above-described suction to both sides is resisted. Thus, it is assumed that the air vortex coefficient Cd can be reduced by reducing the vortex (see arrow e).

このように、上記実施例の車体後部構造は、リヤハッチ3を備えたハッチバック車両1の車体後部構造であって、車体ルーフ(ルーフパネル2参照)は車両前後方向の全域にわたって後面視で上凸の緩円弧形状に形成されたルーフ基本形状αを備える一方、上記ルーフ(ルーフパネル2)の後端部から前方に所定距離L内で、かつ車幅方向の中央部の所定幅Wにおいて上記ルーフ基本形状αより低い位置に形成されたルーフ後方中央凹部4を備え、上記リヤハッチ3の上端部は該リヤハッチ3の閉時にルーフ後端部のルーフ基本形状αの高さに略一致する両肩部20,21と、ルーフ後方中央凹部4の高さに略一致するリヤハッチ中央凹部22とを備え、上記ルーフ後方中央凹部4はその前端部から後方に向けて下降するように形成され、上記ルーフ後方中央凹部4と上記リヤハッチ中央凹部22とを連続する空気流路26が形成されたものである。   Thus, the vehicle body rear structure of the above embodiment is the vehicle body rear structure of the hatchback vehicle 1 provided with the rear hatch 3, and the vehicle body roof (see the roof panel 2) is convex upward in the rear view over the entire vehicle longitudinal direction. While having a basic roof shape α formed in a gentle arc shape, the basic roof is within a predetermined distance L forward from the rear end of the roof (roof panel 2) and at a predetermined width W at the center in the vehicle width direction. A roof rear center recessed portion 4 formed at a position lower than the shape α is provided, and both upper shoulder portions 20 of the rear hatch 3 substantially coincide with the height of the roof basic shape α at the rear end of the roof when the rear hatch 3 is closed. , 21 and a rear hatch central concave portion 22 that substantially matches the height of the roof rear central concave portion 4, and the roof rear central concave portion 4 is formed so as to descend rearward from the front end portion thereof, and -Safe rear central recess 4 and the air passage 26 to continuously and the rear hatch central recess 22 and is formed.

この構成によれば、ルーフ(ルーフパネル2参照)の後端部から前方に所定距離L内で、かつ車幅方向の中央部の所定幅Wにおいて上記ルーフ後方中央凹部4を形成したものである。すなわち、該ルーフ後方中央凹部4は局所的に設けられたものであり、リヤハッチ3側においてはルーフ基本形状αの高さに略一致する両肩部20,21と、ルーフ後方中央凹部4の高さに略一致するリヤハッチ中央凹部22とを備え、このリヤハッチ中央凹部22も局所的に形成されたものである。しかも、空気抗力係数Cdを低減すべく、該ルーフ後方中央凹部4をその前端部から後方に向けて下降すべく形成し、さらに、ルーフ後方中央凹部4とリヤハッチ中央凹部22とを連続する空気流路26を形成したので、ルーフ後端部の全体を下降させる構造と異なり、車両デザインの外観性向上と、各中央凹部4,22による空気流の剥離面積低減との両立を図ることができる。   According to this structure, the said roof back center recessed part 4 is formed in the predetermined width W of the center part of the vehicle width direction in the predetermined distance L ahead from the rear-end part of a roof (refer roof panel 2). . That is, the roof rear center concave portion 4 is provided locally, and on the rear hatch 3 side, both shoulder portions 20, 21 substantially matching the height of the roof basic shape α and the height of the roof rear central concave portion 4 are provided. The rear hatch central recess 22 substantially coincides with this, and the rear hatch central recess 22 is also locally formed. In addition, in order to reduce the air drag coefficient Cd, the roof rear center concave portion 4 is formed so as to descend rearward from the front end portion, and the roof rear central concave portion 4 and the rear hatch central concave portion 22 are continuously connected to the air flow. Since the road 26 is formed, unlike the structure in which the entire rear end of the roof is lowered, it is possible to achieve both improvement in the appearance of the vehicle design and reduction of the air flow separation area by the central recesses 4 and 22.

また、リヤハッチ中央凹部22を跨ぐスポイラ部(リヤスポイラ25参照)を設け、上記空気流路26を流動する空気流が上記スポイラ部(リヤスポイラ25)と上記リヤハッチ中央凹部22との間を通過するように構成したものである。
この構成によれば、上述のスポイラ部(リヤスポイラ25)により空力能性の向上を図ることができる。
Further, a spoiler portion (see rear spoiler 25) straddling the rear hatch central recess 22 is provided so that the air flow flowing through the air flow path 26 passes between the spoiler portion (rear spoiler 25) and the rear hatch central recess 22. It is composed.
According to this configuration, the aerodynamic performance can be improved by the spoiler part (rear spoiler 25) described above.

さらに、上記スポイラ部(リヤスポイラ25)はリヤハッチ3上端部の両肩部20,21の高さと略連続して車幅方向に延びるように形成されたものである。
この構成によれば、スポイラ部(リヤスポイラ25)がリヤハッチ3の上端部の両肩部20,21の高さと略連続して車幅方向に延びるので、車両外観の向上を図ることができる。
Further, the spoiler portion (rear spoiler 25) is formed so as to extend in the vehicle width direction substantially continuously with the heights of the shoulder portions 20, 21 of the upper end portion of the rear hatch 3.
According to this configuration, since the spoiler portion (rear spoiler 25) extends in the vehicle width direction substantially continuously with the heights of the shoulder portions 20, 21 at the upper end portion of the rear hatch 3, the appearance of the vehicle can be improved.

加えて、上記リヤハッチ3はルーフ後端部の雨桶部5において上記ルーフ後方中央凹部4の車幅方向外側に設けた左右一対のヒンジ14,14を介して上開き可能に取付けられ、上記雨桶部5の縦壁部5aは前方に膨出する凹形状を有さないものである。   In addition, the rear hatch 3 is attached to the rain gutter portion 5 at the rear end of the roof so as to be able to open upward via a pair of left and right hinges 14, 14 provided outside the roof rear center recess 4 in the vehicle width direction. The vertical wall portion 5a of the flange portion 5 does not have a concave shape that bulges forward.

換言すれば、雨樋部5の縦壁部5aは、ルーフ(ルーフパネル2参照)の後端部から真っ直ぐ下方に立下がるフラット形状を有するように構成されたものである。
この構成によれば、雨樋部5における縦壁部5aの凹状の前方膨出形状(いわゆるネガ形状)を廃止することができ、ルーフパネル2の成形の容易化と、加工工数の低減と、コストダウンとの両立を図ることができる。
In other words, the vertical wall portion 5a of the rain gutter portion 5 is configured to have a flat shape that falls straight downward from the rear end portion of the roof (see the roof panel 2).

A balance with cost reduction can be achieved.

すなわち、リヤハッチ3は、両肩部20,21と、上述のルーフ後方中央凹部4の高さに略一致するリヤハッチ中央凹部22とを備えているので、リヤハッチ3の開閉時における車幅方向中央部分のリヤハッチ3の上端エッジ部の回動軌跡が小さくなり、このリヤハッチ3の上端エッジ部がルーフ後端部における雨樋部5の縦壁部5aと干渉しなくなるので、該雨樋部5の縦壁部5aにおける前方膨出形状を廃止することができる。   That is, the rear hatch 3 includes both shoulder portions 20 and 21 and a rear hatch central concave portion 22 that substantially matches the height of the roof rear central concave portion 4 described above, so that a central portion in the vehicle width direction when the rear hatch 3 is opened and closed. The rotation trajectory of the upper edge portion of the rear hatch 3 becomes smaller, and the upper edge portion of the rear hatch 3 does not interfere with the vertical wall portion 5a of the rain gutter portion 5 at the rear end portion of the roof. The front bulge shape in the wall 5a can be abolished.

また、上記ルーフ後方中央凹部4および上記リヤハッチ中央凹部22を、その車幅方向中心部4c,22cが両側より低くなるように後面視で略V字状に形成したものである。
この構成によれば、上述の空気流路26はルーフ後方中央凹部4とリヤハッチ中央凹部22とに連続して形成されるが、これらの各中央凹部4,22は後面視で略V字状に形成されているので、上記空気流路26を流れる空気流量を確保、増大することができ、図9で示した中心流cをさらに強くすることができる。

According to this configuration, the air flow path 26 described above is formed continuously to the roof rear center recessed portion 4 and the rear hatch center recessed portion 22, and each of these center recessed portions 4, 22 is substantially V-shaped in rear view. Since it is formed, the flow rate of air flowing through the air flow path 26 can be secured and increased, and the central flow c shown in FIG. 9 can be further strengthened.

さらに、上記ルーフ後方中央凹部4とその車幅方向両端部との境界部xにおいて前後方向に連続する傾斜壁部としての段差部23が形成されたものである。
この構成によれば、上述の傾斜壁部(段差部23参照)により空気流路26の確保が容易になると共に、該傾斜壁部(段差部23)がビードとして作用するので、ルーフ剛性、ルーフ強度の向上を図ることができる。
Further, a step portion 23 is formed as an inclined wall portion continuous in the front-rear direction at a boundary portion x between the roof rear center concave portion 4 and both ends in the vehicle width direction.
According to this configuration, the air channel 26 can be easily secured by the above-described inclined wall portion (see the step portion 23), and the inclined wall portion (step portion 23) acts as a bead. The strength can be improved.

さらにまた、上記リヤハッチ3は樹脂製のアウタパネル15と、樹脂製のインナパネル16とを備えたものである。
この構成によれば、リヤハッチ3の上述の両肩部20,21およびリヤハッチ中央凹部22を樹脂により容易に成形することができる。
Furthermore, the rear hatch 3 includes a resin outer panel 15 and a resin inner panel 16.
According to this structure, both the above-mentioned shoulder parts 20 and 21 and the rear hatch center recessed part 22 of the rear hatch 3 can be easily shape | molded with resin.

なお、実施例で示したように、上記リヤハッチ中央凹部22の車幅方向中心部22cの上端の高さを、上記ヒンジ14のヒンジセンタHC(左右一対のヒンジ14,14のヒンジピン中心を車幅方向に結ぶ仮想ライン)の高さ位置に対して略同等またはそれ以下に設定すると、リヤハッチ中央凹部22の上端エッジ部の回動軌跡が確実に小さくなり、雨樋部5の縦壁部5aにおける前方へ膨出する凹形状β2(図4の仮想線参照)を確実に廃止することができる。   As shown in the embodiment, the height of the upper end of the center portion 22c in the vehicle width direction of the rear hatch central recess 22 is set to the hinge center HC of the hinge 14 (the center of the hinge pin of the pair of left and right hinges 14, 14 is the vehicle width). (The virtual line connecting in the direction) is set to be substantially equal to or lower than the height position of the rear hatch central recess 22, the rotational trajectory of the upper edge portion of the rear hatch central recess 22 is reliably reduced, and the vertical wall 5 a of the rain gutter 5 The concave shape β2 bulging forward (see the phantom line in FIG. 4) can be reliably abolished.
