It is possible to prevent dirt and mud from adhering to the back glass 10 due to entanglement on the rear surface of the vehicle body, and to improve the rear view.
And since the said protrusion part 21 is elongate in the direction substantially orthogonal to the side edge 10S1 of the side part 10S of the said back glass 10, the big flow of a driving | running | working wind is the side of the back glass 10 in the some protrusion part 21 side. It becomes easy to disperse in a direction along the side edge 10S1 of the portion 10S, and the traveling wind can be more easily separated from the side surface of the vehicle body.
As a result, it is not necessary to sharpen the rear of the vehicle to a square shape, and the degree of freedom in design can be increased. Can do.

(2) 前記複数の突出部21は車両前後方向に複数列設けられ、隣り合う列の突出部21が千鳥状に配置されているから、走行風をより細かい流れに分散させることができ、走行風を車体側面からより剥離しやすくすることができる。
また、第2ガーニッシュ20は車両前方側Frに向かって上下の幅が狭くなっているが、隣り合う列の突出部21は千鳥状に配置されているから、第2ガーニッシュ20が、車両前方側Frに向かって上下の幅が狭くなるデザインであっても、より多くの突出部21を設けることができる。
(2) Since the plurality of protrusions 21 are provided in a plurality of rows in the vehicle front-rear direction, and the adjacent rows of protrusions 21 are arranged in a staggered manner, the traveling wind can be dispersed in a finer flow, The wind can be more easily separated from the side of the vehicle body.
The second garnish 20 is narrower in the vertical direction toward the vehicle front side Fr. However, since the protrusions 21 in adjacent rows are arranged in a staggered manner, the second garnish 20 is arranged on the vehicle front side. Even in a design in which the upper and lower widths narrow toward Fr, more protrusions 21 can be provided.

(3) 前記隣り合う列のうち車両前方側Frの列の突出部21が車両後方側Rrの列の突出部21よりも小さく設定されているから、走行風が突出部21にぶつかる衝撃を和らげ、突出部21の抵抗を抑えながら次第に走行風を分散させることができる。また、狭いスペースであっても多くの突出部21を設けることができる。 (3) Since the protrusions 21 in the row on the vehicle front side Fr among the adjacent rows are set to be smaller than the protrusions 21 in the row on the vehicle rear side Rr, the impact of traveling wind on the protrusions 21 is reduced. The traveling wind can be gradually dispersed while suppressing the resistance of the protrusion 21. Moreover, even if it is a narrow space, many protrusion parts 21 can be provided.

(4) 前記第2ガーニッシュ20の上端縁20Jは、前記リヤスポイラー11の後端縁11Uに連続して前記後端縁11Uの延長線上に配置されているから、第2ガーニッシュ20の上端縁20Jに沿って流れてきた走行風がリヤスポイラー11に伝わって剥離し、バックガラス10への走行風の巻き込みを防ぐことができる。 (4) Since the upper end edge 20J of the second garnish 20 is arranged on the extension line of the rear end edge 11U continuously to the rear end edge 11U of the rear spoiler 11, the upper end edge 20J of the second garnish 20 The traveling wind that has flowed along is transmitted to the rear spoiler 11 and peeled off, and the traveling wind can be prevented from being caught in the back glass 10.

(5) 前記第2ガーニッシュ20の下端縁20Kは、前記バックガラス10の下端縁10Kに連続して前記下端縁10Kの延長線上に配置されているから、第2ガーニッシュ20の下端縁20Kに沿って流れてきた走行風が車体後面の下部に流れ、バックガラス10側に巻き込まれるのを防ぐことができる。 (5) Since the lower end edge 20K of the second garnish 20 is arranged on the extended line of the lower end edge 10K continuously to the lower end edge 10K of the back glass 10, it follows the lower end edge 20K of the second garnish 20. It is possible to prevent the traveling wind that has flown through the vehicle from flowing into the lower part of the rear surface of the vehicle body and being caught on the back glass 10 side.

(6) 本実施形態のように、前記サイドガラス41が車両後方側Rrに向かって尖った形状(車両後方側Rrほど上下幅が狭くなる形状)にデザインされた場合、サイドガラス41の上端縁41Jに沿って流れる走行風とサイドガラス41の下端縁41Kに沿って流れる走行風とが車両後方側Rrに行くほど集まっていき、強い流れが生じやすい。また、サイドガラス41の後端部をシャープな形状にする手段として、樹脂製の第1ガーニッシュ40をサイドガラス41の後端部に取り付けてあるため、この第1ガーニッシュ40を設けたことで生ずる段差により、前記強い流れがバックガラス10側に巻き込まれる虞がある。
しかし、本発明の上記構成によれば、前記第2ガーニッシュ20に前記複数の突出部21が設けられているから、前記強い流れを複数の突出部21で効率的に分散させて弱めることができ、より一層バックガラス10への走行風の巻き込みを防ぐことができる。
図4は上記構成の場合の実際の流れを可視化して示したものである。この図4により、サイドガラス41の上端縁41Jに沿って流れてきた大きな走行風F1とサイドガラスの下端縁に沿って流れてきた大きな走行風F2とが突出部21(図2,図3参照)により分散されて小さな流れF3に変わっている様子を確認することができる。
(6) When the side glass 41 is designed to have a sharp shape toward the vehicle rear side Rr (a shape in which the vertical width becomes narrower toward the vehicle rear side Rr) as in the present embodiment, the upper end edge 41J of the side glass 41 The traveling wind that flows along and the traveling wind that flows along the lower end edge 41K of the side glass 41 gather together toward the vehicle rear side Rr, and a strong flow tends to occur. Moreover, since the 1st garnish 40 made from resin is attached to the rear-end part of the side glass 41 as a means which makes the rear-end part of the side glass 41 a sharp shape, by the level | step difference produced by providing this 1st garnish 40 There is a possibility that the strong flow is caught on the back glass 10 side.
However, according to the above configuration of the present invention, since the plurality of protrusions 21 are provided in the second garnish 20, the strong flow can be efficiently dispersed and weakened by the plurality of protrusions 21. Further, it is possible to prevent the traveling wind from being caught in the back glass 10.
FIG. 4 is a visual representation of the actual flow in the case of the above configuration. 4, the large traveling wind F1 flowing along the upper edge 41J of the side glass 41 and the large traveling wind F2 flowing along the lower edge of the side glass are caused by the protrusion 21 (see FIGS. 2 and 3). It can be confirmed that the flow is dispersed and changed to a small flow F3.

[別実施形態]
(1) 前記第2ガーニッシュ20の材質は特に限定されず、例えば、ゴム製、ガラス製であってもよい。
(2) 前記第2ガーニッシュ20を設けることなく、前記突出部21を前記車体側面に直接設けてあってもよい。
(3) 図5(a),図5(b)に示すように、前記突出部21を前記第2ガーニッシュ20に設けることなく、前記第2ガーニッシュ20を次のように構成してもよい。すなわち、前記第2ガーニッシュ20の後端部に、前記後端部の後端縁20Uに沿う断面三角形状の凸部30を前記後端部の上下方向の略全長にわたって設ける。
この場合はサイドガラス4の後端部に集まって強くなった流れを前記凸部30で分散させて弱めるのではなく、前記凸部30により車体側面から剥離させてバックガラス10側に巻き込むのを防いでいる。
[Another embodiment]
(1) The material of the second garnish 20 is not particularly limited, and may be made of rubber or glass, for example.
(2) The projecting portion 21 may be provided directly on the side surface of the vehicle body without providing the second garnish 20.
(3) As shown in FIGS. 5A and 5B, the second garnish 20 may be configured as follows without providing the protruding portion 21 on the second garnish 20. That is, a convex portion 30 having a triangular cross section along the rear end edge 20U of the rear end portion is provided on the rear end portion of the second garnish 20 over substantially the entire length in the vertical direction of the rear end portion.
In this case, the strong flow gathered at the rear end portion of the side glass 4 is not dispersed by the convex portion 30 and weakened, but it is prevented from being peeled off from the side surface of the vehicle body by the convex portion 30 and being caught on the back glass 10 side. It is out.
