Description

本発明は、グリルシャッタに関するものである。   The present invention relates to a grille shutter.

近年は、車両の燃費性能等を向上させるために、車両の前面に設けられたバンパ開口に対してグリルシャッタを設ける場合がある（例えば特許文献１及び特許文献２）。このようなグリルシャッタは、複数のフラップ部材とこれらのフラップ部材を回動させるためのアクチュエータを備えており、バンパ開口からエンジンルームに流れ込む外気の流量を調整する。例えば、特許文献１及び特許文献２では、フラップ部材の高さ方向の略中央に軸部が設けられており、この軸部を中心として回動されることによってフラップ部材が回動される。   In recent years, in order to improve the fuel consumption performance of a vehicle, a grill shutter may be provided for a bumper opening provided on the front surface of the vehicle (for example, Patent Document 1 and Patent Document 2). Such a grille shutter includes a plurality of flap members and an actuator for rotating these flap members, and adjusts the flow rate of outside air flowing into the engine room from the bumper opening. For example, in Patent Document 1 and Patent Document 2, a shaft portion is provided at the approximate center in the height direction of the flap member, and the flap member is rotated by being rotated about this shaft portion.

このようなグリルシャッタでは、例えば高速走行時にフラップ部材が閉鎖される。しかしながら、走行時等においてフラップ部材に車両前方から風が当たると、フラップ部材には、開姿勢方向にトルクが作用することになり、フラップ部材同士の間に隙間が生じることが考えられる。 また、フラップ部材は、一般的に樹脂成形品であることから、閉姿勢において強い風を受けることによって一部が撓み、これによってもフラップ部材同士の間に隙間が生じることが考えられる。このようにフラップ部材同士の間に隙間が生じると、当該隙間から外気がエンジンルームの内部に流れ込み、燃費の改善効果が減少することになる。   In such a grill shutter, for example, the flap member is closed when traveling at high speed. However, when wind hits the flap member from the front of the vehicle during traveling or the like, torque acts on the flap member in the opening posture direction, and a gap may be generated between the flap members. Further, since the flap member is generally a resin molded product, it is considered that a part of the flap member is bent by receiving a strong wind in the closed posture, and this also causes a gap between the flap members. When a gap is generated between the flap members in this way, outside air flows into the engine room from the gap and the effect of improving fuel consumption is reduced.

本発明は、上述する問題点に鑑みてなされたもので、複数のフラップ部材を備えるグリルシャッタにおいて、フラップ部材同士の間に隙間が生じることを防止し、閉姿勢とされたフラップ部材同士の密着性を向上させることを目的とする。   The present invention has been made in view of the above-described problems, and in a grille shutter having a plurality of flap members, the gap members are prevented from forming gaps, and the close contact between the flap members is achieved. The purpose is to improve the performance.

本発明は、上記課題を解決するための手段として、以下の構成を採用する。   The present invention adopts the following configuration as means for solving the above-described problems.

第１の発明は、車両に設置されると共にフラップ部材を複数備えるグリルシャッタであって、少なくともいずれかの上記フラップ部材が、水平に延在すると共にフレームに対して軸支される軸部と、上記軸部を中心として回動することにより開閉されると共に閉姿勢にて縁部が車両前方から他の上記フラップ部材の上記軸部に当接するフラップ本体とを備えるという構成を採用する。   A first invention is a grille shutter that is installed in a vehicle and includes a plurality of flap members, wherein at least one of the flap members extends horizontally and is supported by a frame. A configuration is adopted in which the flap body is provided with a flap body that is opened and closed by rotating about the shaft portion and that has an edge portion that contacts the shaft portion of another flap member from the front of the vehicle in a closed posture.

第２の発明は、上記第１の発明において、上記フラップ本体の上縁部及び下縁部の一方に上記軸部が接続され、上記フラップ本体の上縁部及び下縁部の他方が他の上記フラップ部材の上記軸部に当接するという構成を採用する。   According to a second invention, in the first invention, the shaft portion is connected to one of the upper edge portion and the lower edge portion of the flap body, and the other of the upper edge portion and the lower edge portion of the flap body is the other. A configuration is adopted in which the flap member abuts on the shaft portion.

第３の発明は、上記第２の発明において、上記軸部の延在方向と沿う方向から見て、上記フラップ本体が、上記軸部と接続されると共に上記閉姿勢にて鉛直方向に延在する第１鉛直部位と、上記第１鉛直部位よりも車両の前方側に位置すると共に上記閉姿勢にて鉛直方向に延在する第２鉛直部位と、上記第１鉛直部位と上記第２鉛直部位とを接続する接続部位とを備えるという構成を採用する。   According to a third invention, in the second invention, the flap body is connected to the shaft portion and extends in the vertical direction in the closed posture as viewed from a direction along the extending direction of the shaft portion. A first vertical part, a second vertical part that is located on the front side of the vehicle with respect to the first vertical part and extends in the vertical direction in the closed posture, and the first vertical part and the second vertical part A configuration is provided that includes a connection portion that connects the two.

第４の発明は、上記第３の発明において、上記フラップ本体の車両の後方側の面に設けられると共に上記第２鉛直部位と上記接続部位とに固定されるリブを備えるという構成を採用する。   According to a fourth aspect of the present invention, in the third aspect of the present invention, the flap main body includes a rib that is provided on a rear surface of the vehicle and is fixed to the second vertical portion and the connection portion.

本発明によれば、フラップ本体は、フラップ部材が閉姿勢とされたときに他のフラップ部材の軸部に車両前方側から当接される。このようにフラップ本体が当接されるフラップ部材の軸部はフレームに軸支されており、車両前後方向への移動は規制されている。つまり、本発明によれば、閉姿勢において、フラップ本体は、車両の後方側から他のフラップ部材の軸部によって支えられている。このようなフラップ部材に対して、車両の前方側から風が当たったとしても、フラップ部材同士の密着性が高まるのみであり、フラップ部材同士の間に隙間が生じることを防止することができる。また、他のフラップ部材の軸部に支えられることによってフラップ部材が撓むことを防止することができ、これによってもフラップ部材同士の間に隙間が生じることを防止することができる。したがって、本発明によれば、複数のフラップ部材を備えるグリルシャッタにおいて、フラップ部材同士の間に隙間が生じることを防止し、閉姿勢とされたフラップ部材同士の密着性を向上させることができる。   According to the present invention, the flap body comes into contact with the shaft portion of the other flap member from the front side of the vehicle when the flap member is in the closed posture. In this manner, the shaft portion of the flap member with which the flap main body abuts is pivotally supported by the frame, and movement in the vehicle front-rear direction is restricted. That is, according to the present invention, in the closed posture, the flap main body is supported by the shaft portion of the other flap member from the rear side of the vehicle. Even if wind hits such a flap member from the front side of the vehicle, only the adhesion between the flap members is increased, and a gap can be prevented from being generated between the flap members. Moreover, it can prevent that a flap member bends by being supported by the axial part of another flap member, and it can prevent that a clearance gap produces between flap members also by this. Therefore, according to the present invention, in a grille shutter including a plurality of flap members, it is possible to prevent a gap from being generated between the flap members and to improve the adhesion between the flap members in the closed posture.

本発明の一実施形態におけるグリルシャッタを含む車両の正面図である。1 is a front view of a vehicle including a grill shutter according to an embodiment of the present invention. 本発明の一実施形態におけるグリルシャッタの正面図である。It is a front view of the grille shutter in one embodiment of the present invention. 本発明の一実施形態におけるグリルシャッタが備えるフラップ部材を示す図であり、（ａ）が斜視図であり、（ｂ）が正面図であり、（ｃ）が側面図である。It is a figure which shows the flap member with which the grille shutter in one Embodiment of this invention is provided, (a) is a perspective view, (b) is a front view, (c) is a side view. 図２のＡ−Ａ線断面図である。It is the sectional view on the AA line of FIG.

以下、図面を参照して、本発明に係るグリルシャッタの一実施形態について説明する。なお、以下の図面において、各部材を認識可能な大きさとするために、各部材の縮尺を適宜変更している。   Hereinafter, an embodiment of a grille shutter according to the present invention will be described with reference to the drawings. In the following drawings, the scale of each member is appropriately changed in order to make each member a recognizable size.

図１は、本実施形態のグリルシャッタ１を含む車両１００の正面図である。この図に示すように、車両１００の前面には、エンジンルーム内に外気を取り込むためのバンパ開口１０１が設けられている。本実施形態のグリルシャッタ１は、このようなバンパ開口１０１に設けられている。   FIG. 1 is a front view of a vehicle 100 including a grill shutter 1 of the present embodiment. As shown in this figure, a bumper opening 101 for taking outside air into the engine room is provided on the front surface of the vehicle 100. The grille shutter 1 of the present embodiment is provided in such a bumper opening 101.

図２は、本実施形態のグリルシャッタ１の正面図である。この図に示すように、本実施形態のグリルシャッタ１は、フレーム２と、アクチュエータ３と、フラップ部材４とを備えている。   FIG. 2 is a front view of the grille shutter 1 of the present embodiment. As shown in this figure, the grill shutter 1 of this embodiment includes a frame 2, an actuator 3, and a flap member 4.

フレーム２は、バンパ開口１０１の縁に沿って設けられる矩形状の環状形状とされている。このフレーム２は、図２に示すように、上部２ａと、下部２ｂと、２つの側部２ｃとを有しており、これらの上部２ａと、下部２ｂと、２つの側部２ｃとが接続されることによって環状とされている。また、フレーム２は、最も下方に配置されるフラップ部材４（下段フラップ部材４３）の下側の縁部が当接する当接部２ｄを備えている（図４参照）。この当接部２ｄは、車幅方向に延在して設けられており、下部２ｂから上方に向けて突出するように形成されている。   The frame 2 has a rectangular annular shape provided along the edge of the bumper opening 101. As shown in FIG. 2, the frame 2 has an upper portion 2a, a lower portion 2b, and two side portions 2c. The upper portion 2a, the lower portion 2b, and the two side portions 2c are connected to each other. It is made circular by being done. Further, the frame 2 includes an abutting portion 2d with which the lower edge of the flap member 4 (lower flap member 43) disposed on the lowermost side abuts (see FIG. 4). The contact portion 2d is provided so as to extend in the vehicle width direction, and is formed so as to protrude upward from the lower portion 2b.

アクチュエータ３は、上端がフレーム２の上部２ａに接続され、下端がフレーム２の下部２ｂに接続され、車幅方向の中央に配置されている。このアクチュエータ３によって、フレーム２によって囲われた領域が、車幅方向に左右の領域（左領域Ｒａと右領域Ｒｂ）に分けて区画されている。このようなアクチュエータ３は、複数のフラップ部材４の各々に接続されており、フラップ部材４を同期して回転駆動する。なお、本実施形態のグリルシャッタ１においては、全てのフラップ部材４がアクチュエータ３に接続されているが、例えば１つのフラップ部材４のみをアクチュエータ３に接続し、このフラップ部材４と他のフラップ部材４をリンク部材で連結するようにしても良い。   The actuator 3 has an upper end connected to the upper part 2a of the frame 2 and a lower end connected to the lower part 2b of the frame 2 and is arranged at the center in the vehicle width direction. The actuator 3 divides the region surrounded by the frame 2 into left and right regions (left region Ra and right region Rb) in the vehicle width direction. Such an actuator 3 is connected to each of the plurality of flap members 4 and rotationally drives the flap members 4 in synchronization. In the grill shutter 1 of the present embodiment, all the flap members 4 are connected to the actuator 3. For example, only one flap member 4 is connected to the actuator 3, and this flap member 4 and other flap members are connected. 4 may be connected by a link member.

図３は、フラップ部材４を示す図であり、（ａ）が斜視図であり、（ｂ）が正面図であり、（ｃ）が側面図である。これらの図に示すように、フラップ部材４は、軸部４ａと、フラップ本体４ｂと、リブ４ｃが一体化された部材である。軸部４ａは、車幅方向に直線状かつ水平に延在する部位であり、一端がフレーム２の側部２ｃに軸支され、他端がアクチュエータ３に接続されている。この軸部４ａは、アクチュエータ３から伝達される回転動力によって、軸芯を中心として回動される。   3A and 3B are views showing the flap member 4, in which FIG. 3A is a perspective view, FIG. 3B is a front view, and FIG. 3C is a side view. As shown in these drawings, the flap member 4 is a member in which a shaft portion 4a, a flap body 4b, and a rib 4c are integrated. The shaft portion 4 a is a portion that extends linearly and horizontally in the vehicle width direction, and has one end pivotally supported by the side portion 2 c of the frame 2 and the other end connected to the actuator 3. The shaft portion 4 a is rotated around the shaft core by the rotational power transmitted from the actuator 3.

フラップ本体４ｂは、途中部位が屈曲された板状の部材であり、第１鉛直部位４ｂ１と、第２鉛直部位４ｂ２と、接続部位４ｂ３とを有している。第１鉛直部位４ｂ１は、フラップ部材４が閉姿勢のときに、軸部４ａの延在方向と沿う方向（車幅方向）から見て、軸部４ａから下方に向けて延在する部位である。この第１鉛直部位４ｂ１は、上端が軸部４ａに接続されている。また、この第１鉛直部位４ｂ１の板厚は、軸部４ａの直径と略同一とされている。   The flap body 4b is a plate-like member having a bent portion in the middle, and has a first vertical portion 4b1, a second vertical portion 4b2, and a connection portion 4b3. The first vertical portion 4b1 is a portion that extends downward from the shaft portion 4a when viewed from the direction (vehicle width direction) along the extending direction of the shaft portion 4a when the flap member 4 is in the closed posture. . The first vertical portion 4b1 has an upper end connected to the shaft portion 4a. The plate thickness of the first vertical portion 4b1 is substantially the same as the diameter of the shaft portion 4a.

第２鉛直部位４ｂ２は、第１鉛直部位４ｂ１の下方でかつ第１鉛直部位４ｂ１よりも車両の前方側に位置する部位である。この第２鉛直部位４ｂ２の上端部の高さは、車両の前方から見て第１鉛直部位４ｂ１の下端部に重なる高さとされている。接続部位４ｂ３は、第１鉛直部位４ｂ１の下端部と第２鉛直部位４ｂ２の上端部とを接続する部位である。   The second vertical part 4b2 is a part located below the first vertical part 4b1 and on the front side of the vehicle with respect to the first vertical part 4b1. The height of the upper end portion of the second vertical portion 4b2 is a height that overlaps the lower end portion of the first vertical portion 4b1 when viewed from the front of the vehicle. The connection part 4b3 is a part that connects the lower end part of the first vertical part 4b1 and the upper end part of the second vertical part 4b2.

なお、このような接続部位４ｂ３によって第１鉛直部位４ｂ１と接続されている第２鉛直部位４ｂ２は、裏面の車両前後方向の位置が、第１鉛直部位４ｂ１の表面の車両前後方向の位置と略同一とされている。つまり、本実施形態においては、第２鉛直部位４ｂ２が第１鉛直部位４ｂ１に対してこの第１鉛直部位４ｂ１の厚み分（軸部４ａの直径分）だけ車両の前方に変位されている。これによって、第２鉛直部位４ｂ２の裏面が軸部４ａに当接したときに、第１鉛直部位４ｂ１の表面と第２鉛直部位４ｂ２の表面とが鉛直面となる。   The second vertical part 4b2 connected to the first vertical part 4b1 by such a connection part 4b3 has a position in the vehicle front-rear direction on the back surface that is substantially the same as the position in the vehicle front-rear direction on the surface of the first vertical part 4b1. Identical. That is, in the present embodiment, the second vertical portion 4b2 is displaced forward of the vehicle by the thickness of the first vertical portion 4b1 (the diameter of the shaft portion 4a) with respect to the first vertical portion 4b1. Thus, when the back surface of the second vertical part 4b2 comes into contact with the shaft portion 4a, the surface of the first vertical part 4b1 and the surface of the second vertical part 4b2 become vertical surfaces.

リブ４ｃは、側方から見た形状が三角形状とされた薄板状の部位であり、接続部位４ｂ３の下面と第２鉛直部位４ｂ２の背面とに接続されている。このようなリブ４ｃは、フラップ本体４ｂの裏面に、車幅方向に離散的に複数設けられている。これらのリブ４ｃが形成されることによって、フラップ本体４ｂが撓み難くなり、フラップ部材４の強度が向上される。また、これらのリブ４ｃは、車両の前方からフラップ本体４ｂが風を受けたときに、車両前方から見た表面積が小さく撓み難い接続部位４ｂ３に上端が固定されている。このため、上記風を受けたときに撓みやすい第２鉛直部位４ｂ２をより安定的に後方から支えることができる。   The rib 4c is a thin plate-like portion having a triangular shape when viewed from the side, and is connected to the lower surface of the connection portion 4b3 and the back surface of the second vertical portion 4b2. A plurality of such ribs 4c are provided discretely in the vehicle width direction on the back surface of the flap body 4b. By forming these ribs 4c, the flap body 4b becomes difficult to bend and the strength of the flap member 4 is improved. Further, the upper ends of these ribs 4c are fixed to a connection portion 4b3 that has a small surface area when viewed from the front of the vehicle and is difficult to bend when the flap body 4b receives wind from the front of the vehicle. For this reason, it is possible to more stably support the second vertical portion 4b2 that is easily bent when receiving the wind from behind.

このようなフラップ部材４は、図２に示すように、フレーム２で囲まれた領域がアクチュエータ３で区画されることで形成された上述の左領域Ｒａと右側領域Ｒｂとの各々の領域に対して、鉛直方向に配列されて３つずつ設置されている。以下の説明では、説明の便宜上、各領域に設置された３つのフラップ部材４のうち、上側に配置されたフラップ部材４を上段フラップ部材４１、真ん中に配置されたフラップ部材４を中段フラップ部材４２、下側に配置されたフラップ部材４を下段フラップ部材４３と称する。なお、本実施形態においては、各領域に３つのフラップ部材４を設置しているが、これに限らず、各領域に２つあるいは４つ以上のフラップ部材４を設置しても良い。   As shown in FIG. 2, the flap member 4 has the above-described left region Ra and right region Rb formed by dividing the region surrounded by the frame 2 with the actuator 3. And three are arranged in the vertical direction. In the following description, for convenience of explanation, among the three flap members 4 installed in each region, the upper flap member 41 is the upper flap member 41 and the middle flap member 42 is the flap member 4 arranged in the middle. The flap member 4 disposed on the lower side is referred to as a lower flap member 43. In the present embodiment, the three flap members 4 are installed in each region. However, the present invention is not limited to this, and two or more flap members 4 may be installed in each region.

図４は、図２のＡ−Ａ線断面図である。フラップ部材４は、アクチュエータ３によって、軸部４ａが回動されることによって軸部４ａを中心として開閉される。フラップ部材４は、図４において実線で示す閉姿勢と、図４において仮想線で示す開姿勢との間に開閉される。上段フラップ部材４１と、中段フラップ部材４２と、下段フラップ部材４３とは、上述のようにアクチュエータ３によって同期して回動される。   4 is a cross-sectional view taken along line AA in FIG. The flap member 4 is opened and closed around the shaft portion 4a by rotating the shaft portion 4a by the actuator 3. The flap member 4 is opened and closed between a closed posture indicated by a solid line in FIG. 4 and an open posture indicated by a virtual line in FIG. The upper flap member 41, the middle flap member 42, and the lower flap member 43 are rotated synchronously by the actuator 3 as described above.

このため、これらのフラップ部材４が閉姿勢である場合には、図４の実線で示すように、上段フラップ部材４１の第２鉛直部位４ｂ２の下側の縁部（すなわち上段フラップ部材４１の下側の縁部）が車両の前方側から中段フラップ部材４２の軸部４ａに当接される。また、中段フラップ部材４２の第２鉛直部位４ｂ２の下側の縁部（すなわち中段フラップ部材４２の下側の縁部）が車両の前方側から下段フラップ部材４３の軸部４ａに当接される。また、下段フラップ部材４３の第２鉛直部位４ｂ２の下側の縁部（すなわち下段フラップ部材４３の下側の縁部）がフレーム２の下部２ｂに形成された当接部２ｄに車両の前方側から当接される。   For this reason, when these flap members 4 are in the closed posture, as shown by the solid line in FIG. 4, the lower edge of the second vertical portion 4b2 of the upper flap member 41 (that is, the lower portion of the upper flap member 41). Side edge) is brought into contact with the shaft portion 4a of the middle flap member 42 from the front side of the vehicle. Further, the lower edge of the second vertical portion 4b2 of the middle flap member 42 (that is, the lower edge of the middle flap member 42) is brought into contact with the shaft portion 4a of the lower flap member 43 from the front side of the vehicle. . Further, the lower edge of the second vertical portion 4b2 of the lower flap member 43 (that is, the lower edge of the lower flap member 43) is placed on the abutting portion 2d formed on the lower portion 2b of the frame 2 on the front side of the vehicle. It is contacted from.

一方、フラップ部材４が開姿勢である場合には、図４の仮想線で示すように、閉姿勢に対してフラップ部材４が車両の前方側に開くことにより、上段フラップ部材４１と中段フラップ部材４２との間、中段フラップ部材４２と下段フラップ部材４３との間、及び、下段フラップ部材４３とフレーム２の下部２ｂとの間に隙間が形成される。   On the other hand, when the flap member 4 is in the open posture, the upper flap member 41 and the middle flap member are opened by opening the flap member 4 toward the front side of the vehicle with respect to the closed posture, as indicated by the phantom line in FIG. 42, gaps are formed between the middle flap member 42 and the lower flap member 43, and between the lower flap member 43 and the lower portion 2 b of the frame 2.

このような本実施形態のグリルシャッタ１においては、フラップ部材４が閉姿勢とされることによって、上段フラップ部材４１が中段フラップ部材４２に密着し、中段フラップ部材４２が下段フラップ部材４３に密着し、下段フラップ部材４３がフレーム２に密着する。このため、フラップ部材４同士の間の隙間がなくなり、エンジンルームへの外気の流入が停止される。一方、フラップ部材４が開姿勢とされることによって、上段フラップ部材４１と中段フラップ部材４２との間、中段フラップ部材４２と下段フラップ部材４３との間、及び、下段フラップ部材４３とフレーム２の下部２ｂとの間に隙間が形成されエンジンルームへの外気が流入可能となる。   In the grill shutter 1 according to this embodiment, the flap member 4 is in the closed posture, so that the upper flap member 41 is in close contact with the middle flap member 42 and the middle flap member 42 is in close contact with the lower flap member 43. The lower flap member 43 is in close contact with the frame 2. For this reason, there is no gap between the flap members 4, and the inflow of outside air into the engine room is stopped. On the other hand, when the flap member 4 is in the open posture, the upper flap member 41 and the middle flap member 42, between the middle flap member 42 and the lower flap member 43, and between the lower flap member 43 and the frame 2. A gap is formed between the lower portion 2b and the outside air can flow into the engine room.

以上のような本実施形態のグリルシャッタ１によれば、上段フラップ部材４１及び中段フラップ部材４２のフラップ本体４ｂは、フラップ部材４が閉姿勢とされたときに他のフラップ部材４の軸部４ａに車両前方側から当接される。また、フラップ部材４の軸部４ａはフレームに軸支されており、車両前後方向への移動は規制されている。つまり、本実施形態のグリルシャッタ１によれば、フラップ部材４が閉姿勢の場合に、上段フラップ部材４１及び中段フラップ部材４２のフラップ本体４ｂは、車両の後方側から他のフラップ部材４の軸部４ａによって支えられている。このような上段フラップ部材４１及び中段フラップ部材４２に対して、車両の前方側から風が当たったとしても、フラップ部材４同士の密着性が高まるのみであり、フラップ部材４同士の間に隙間が生じることを防止することができる。また、他のフラップ部材４の軸部４ａに支えられることによってフラップ部材４が撓むことを防止することができ、これによってもフラップ部材４同士の間に隙間が生じることを防止することができる。したがって、本実施形態のグリルシャッタ１によれば、フラップ部材４同士の間に隙間が生じることを防止し、閉姿勢とされたフラップ部材４同士の密着性を向上させることができる。   According to the grill shutter 1 of the present embodiment as described above, the flap body 4b of the upper flap member 41 and the middle flap member 42 has the shaft portion 4a of the other flap member 4 when the flap member 4 is in the closed position. It contacts from the vehicle front side. Further, the shaft portion 4a of the flap member 4 is pivotally supported by the frame, and movement in the vehicle front-rear direction is restricted. That is, according to the grille shutter 1 of the present embodiment, when the flap member 4 is in the closed posture, the flap main body 4b of the upper flap member 41 and the middle flap member 42 is the axis of the other flap member 4 from the rear side of the vehicle. It is supported by the part 4a. Even if wind hits the upper flap member 41 and the middle flap member 42 from the front side of the vehicle, only the adhesion between the flap members 4 is increased, and there is a gap between the flap members 4. It can be prevented from occurring. Moreover, it can prevent that the flap member 4 bends by being supported by the axial part 4a of the other flap member 4, and it can prevent that a clearance gap produces between flap members 4 also by this. . Therefore, according to the grill shutter 1 of the present embodiment, it is possible to prevent a gap from being generated between the flap members 4 and improve the adhesion between the flap members 4 in the closed posture.
