Description

本発明は、主として高速鉄道車両に用いられる、鉄道車両の連結部用外幌に関するものである。   The present invention relates to an outer hood for a connecting portion of a railway vehicle, which is mainly used for a high-speed railway vehicle.
従来、鉄道車両間の空間部を覆う車両用幌は、車両間の内側全周を覆う内幌と、その内幌の外側において車両の左右側部のみに設けられる外幌から構成されている。   2. Description of the Related Art Conventionally, a vehicle hood that covers a space between railway vehicles is composed of an inner hood that covers the entire inner periphery between vehicles, and an outer hood that is provided only on the left and right sides of the vehicle outside the inner hood.
前記内幌は、蛇腹構造に形成され、車内に風雪、ほこり等の異物が侵入するのを防止する役割を果たすが、車両連結部の空気抵抗の低減、空気流を原因とした車外騒音の発生の低減については十分とはいえない。   The inner hood is formed in a bellows structure and serves to prevent foreign objects such as wind, snow, and dust from entering the vehicle, but it reduces the air resistance of the vehicle connection part and generates external noise due to airflow. It cannot be said that the reduction is sufficient.
一方、外幌は前後車両の各々の側部に取り付けられる断面U字状のゴム板で構成され、車両を側面から見たときの美感の向上を確保すると共に、ホームからの乗客の転落を防止する役割を果たしている。   On the other hand, the outer hood is composed of rubber plates with a U-shaped cross section that are attached to the sides of the front and rear vehicles, ensuring improved aesthetics when the vehicle is viewed from the side and preventing passengers from falling from the platform. Playing a role.
このように、外幌は、前後車両の各々の車体端面において前後の側部のみに設けられ、しかも車両の連結部において、外幌は間隔を存して取り付けられているので、風切り音、車輪とレールの摩擦音、レール継ぎ目でのたたき音、車輪の転動音、パンタグラフ擦り音、鉄橋通過時の共鳴音等の車外騒音が内幌を通じてそのまま車両内に侵入してくるのを防止できない。また、そのような外幌は、高速鉄道車両の場合には、走行抵抗の低減を図る目的では大きな効果が期待できない。   Thus, the outer hood is provided only on the front and rear sides of the vehicle body end surfaces of the front and rear vehicles, and the outer hood is attached at intervals in the connecting portion of the vehicle. It is impossible to prevent outside noise such as rail friction noise, rattling noise at the rail joints, wheel rolling noise, pantograph rubbing noise and resonance noise when passing through the iron bridge from entering the vehicle as it is. In addition, such an outer hood cannot be expected to have a great effect for the purpose of reducing running resistance in the case of a high-speed railway vehicle.
そこで、車両連結部の空気抵抗の低減、空気流を原因とした車外騒音の発生の低減を目的として、前後車両の各々の車体端面において、左右の側部部分だけでなく、上側部分(屋根側部分)及び左右の側部部分に亘って外幌を設けたものが提案されている(特許文献1,2,3,4参照)。   Therefore, for the purpose of reducing the air resistance of the vehicle connecting part and reducing the generation of external noise due to the air flow, not only the left and right side parts but also the upper part (the roof side) And an outer hood provided over the left and right side portions have been proposed (see Patent Documents 1, 2, 3, and 4).
さらに床下部から騒音侵入の防止を目的として、車両間の空間部の周囲を覆う上下左右の直線部材と、それに接続され四隅に配設されるコーナー部材とから、外幌を構成するものが提案されている(例えば特許文献5参照)。

In addition, for the purpose of preventing noise intrusion from the bottom of the floor, a proposal is made of an outer hood composed of upper, lower, left and right linear members that cover the space between the vehicles, and corner members that are connected to the corners and arranged at the four corners. (See, for example, Patent Document 5).
Japanese Utility Model Publication No. 4-92480 (Claim 1, paragraph numbers 0007 to 0010 and FIGS. 1 and 2) JP-A-9-286329 (paragraph number 0022 and FIG. 1) Japanese Patent Laid-Open No. 11-171011 (paragraph number 0002 and FIGS. 8 and 9) JP 2003-291804 A (paragraph number 0010 and FIGS. 1 and 2) JP 2003-112625 A (pages 3 and 4)
特許文献5に記載の技術においては、外幌の先端部分同士は接触しているので、車両が急カーブ部や分岐ポイントなどの偏倚通過時に、対向する外幌同士の圧縮やバタ付きのために、コーナー部分の変形が著しくなり、耐久性が低下する。   In the technique described in Patent Document 5, since the front end portions of the outer hood are in contact with each other, when the vehicle passes through a deviation such as a sharp curve portion or a branching point, the compression of the outer hoods facing each other and the flap are caused. , Deformation of the corner portion becomes remarkable and durability is lowered.
また、そのような耐久性の低下を回避するために、前述する特許文献1記載の技術は外幌の両側部に位置する部分と上側(屋根)に位置する部分とを結合するコーナー部を、伸縮自在の蛇腹部材又はセグメント複合材で形成するが、そのようにすると、構造が複雑で、コストアップの原因となる。   Further, in order to avoid such a decrease in durability, the technique described in Patent Document 1 described above includes a corner portion that joins a portion located on both sides of the outer hood and a portion located on the upper side (roof), Although it is formed of a stretchable bellows member or a segment composite material, doing so causes a complicated structure and increases costs.
また、特許文献2〜4記載の技術は、裾部側からひだを設けたり、外幌の展開形状を工夫したり、裾部から円弧状頂部の終点に向かって所定幅の切欠部を設けたりしているものの、それらは前後の外幌が間隔を存して設けられており、また、車体端面への取付性を高めるためにひだ等を設けているものであり、急カーブ部や分岐ポイントなどの偏倚通過時における前記コーナー部分における変形については十分に対応することができない。   In addition, the techniques described in Patent Documents 2 to 4 provide pleats from the skirt side, devise the deployment shape of the outer hood, or provide a notch with a predetermined width from the skirt toward the end of the arcuate top. However, they have front and rear outer hoods spaced apart, and are provided with pleats etc. to improve the attachment to the end face of the car body. It is not possible to sufficiently cope with the deformation at the corner portion when passing through the bias.
この発明は、偏倚通過時に、対向(接触)する外幌同士が擦れ合う際の変形を無理なく吸収し、耐久性を向上させた鉄道車両の連結部用外幌を提供することを目的とする。   An object of the present invention is to provide an outer hood for a connecting portion of a railway vehicle which absorbs deformation when the outer hoods facing (contact) each other rub against each other when passing through a bias and has improved durability.
請求項1の発明は、車体端面の上側縁付近に取り付けられる天井幌部材と、車体端面の左右側縁付近に取り付けられる左右側部幌部材と、車体端面の上側左右コーナー部に取り付けられ前記天井幌部材と左右側部幌部材と結合する左右の肩幌部材とを有し、前記各幌部材が、可撓性弾性シート材料を折り曲げることにより、湾曲した先端部と、車体端面の外側縁側と車体中心側とに間隔を存して取り付けられる外側及び内側基部と、前記先端部と外側及び内側基部との間を連接する外側及び内側中間連接部とを有する断面U字形状とされる鉄道車両の連結部用外幌であって、前記車体端面に取り付けられた状態において、対向する外幌に弾性接触するものであり、 前記肩幌部材の外側縁側部分又は車体中心側部分に、前記基部の中間部位から前記中間連接部に亘って延び、対向する外幌との形状の段差を吸収する凹溝部を形成する複数の薄肉部分が、車両前後方向に平行に設けられている構造を設けていることを特徴とする。   According to the first aspect of the present invention, there is provided a ceiling hood member attached near the upper edge of the vehicle body end surface, a left and right side hood member attached near the left and right edges of the vehicle body end surface, and the ceiling hood member attached to the upper left and right corner portions of the vehicle body end surface. A hood member and left and right shoulder hood members coupled to the left and right side hood members, wherein each of the hood members is bent by a flexible elastic sheet material, and the outer edge side of the end face of the vehicle body A railway vehicle having a U-shaped cross section having an outer and inner base portion that is attached to the vehicle body center side with an interval, and an outer and inner intermediate connecting portion that connects the tip portion with the outer and inner base portions. An outer hood for the connecting portion, wherein the outer hood is attached to the end face of the vehicle body and elastically contacts the opposing outer hood. Is it an intermediate part? A structure is provided in which a plurality of thin-walled portions that extend over the intermediate connecting portion and form a concave groove portion that absorbs a step difference in shape with the opposed outer hood are provided in parallel in the vehicle longitudinal direction. And
このようにすれば、例えば偏倚通過時において、一方の外幌が他方の外幌に入ろうとすると、他方の外幌において、薄肉部分として形成される凹溝部の溝幅が、その薄肉部分自体が有する可撓性及び弾性でもって広がり、一方の外幌との形状差(形状の段差)を吸収するように変形し、相手形状(一方の外幌の形状)に追従し、各肩幌部材の変形に無理な負荷が作用しない。   In this way, for example, when one outer hood tries to enter the other outer hood when passing through a bias, the groove width of the recessed groove portion formed as a thin portion in the other outer hood is reduced. It expands with its flexibility and elasticity, deforms to absorb the shape difference (shape step) with one outer hood, follows the other shape (shape of one outer hood), and each shoulder hood member Unreasonable load does not act on deformation.
請求項2に記載のように、前記凹溝部は、溝深さが一定で、前記外側基部の中間部位から、外側中間連接部、先端部、及び内側中間連接部を経て内側基部の中間部位まで形成され、少なくとも外側基部、外側中間連接部及び先端部の上側部分に形成される凹溝部は、鉄道車両の直線走行状態では閉じる構成とすることができる。ここで、「凹溝部が閉じる」とは、凹溝部の(開口部分)の溝幅がほぼ0になっていることをいい、少し隙間が開いている場合も含まれる。   According to a second aspect of the present invention, the groove portion has a constant groove depth, from the intermediate portion of the outer base portion to the intermediate portion of the inner base portion through the outer intermediate connecting portion, the tip portion, and the inner intermediate connecting portion. The groove portions formed and formed at least on the outer base portion, the outer intermediate connecting portion, and the upper portion of the tip portion can be configured to be closed in a straight traveling state of the railway vehicle. Here, “the closed groove portion is closed” means that the groove width of the (opening portion) of the recessed groove portion is almost 0, and includes a case where a gap is slightly opened.
このようにすれば、少なくとも外側基部、外側中間連接部及び先端部の上側部分に形成される凹溝部は、外幌のコーナー部分(肩幌部材)にほとんど変形が生じない直線走行時等に閉じられるので、空気騒音の発生を防止できる。   In this way, at least the outer base portion, the outer intermediate connecting portion, and the concave groove portion formed at the upper portion of the tip end portion are closed during straight running where the corner portion of the outer hood (shoulder hood member) hardly deforms. Therefore, generation of air noise can be prevented.
請求項3に記載のように、前記先端部には、前記内側基部寄りに偏倚して薄肉部分が形成され、この先端部の薄肉部分と前記凹溝部を構成する薄肉部分とが同じ肉厚であることが望ましい。   According to a third aspect of the present invention, the distal end portion is formed near the inner base portion to form a thin portion, and the thin portion of the distal end portion and the thin portion constituting the concave groove portion have the same thickness. It is desirable to be.
このようにすれば、先端部の薄肉部分と凹溝部を構成する薄肉部分とが同じ肉厚であるので、一方の外幌が他方の外幌に入ろうとする際に、相対向する先端部同士の接触によりそれらが内側に折れ曲がり変形しようとする動作と、溝幅が広がり変形しようとする動作とがバランスよく行われることにより、肩幌部材に無理な負荷がかかりにくくなり、耐久性の点で有利となる。   In this way, since the thin portion of the tip portion and the thin portion constituting the concave groove portion have the same thickness, when one outer hood attempts to enter the other outer hood, the opposite tip portions are in contact with each other. Because of the balance between the action of bending and deforming inward due to contact, and the action of expanding the groove width and trying to deform, it is difficult to apply an excessive load on the shoulder hood member, and in terms of durability It will be advantageous.
以上のように、本発明は、車体端面の上側左右コーナー部に取り付けられる肩幌部材の外側縁側部分又は車体中心側部分に、基部の中間部位から中間連接部に亘って、車両前後方向に延びる凹溝部を構成する薄肉部分を一定間隔を存して設けているので、一方の外幌が他方の外幌内に入ろうとすると、他方の外幌において、凹溝部は広がり、一方の外幌との形状差を吸収するように変形し、相手形状に追従し、無理な負荷が作用しなくなる。よって、耐久性が向上する。   As described above, the present invention extends in the vehicle longitudinal direction from the intermediate portion of the base portion to the intermediate connecting portion on the outer edge side portion or the vehicle body center side portion of the shoulder hood member attached to the upper left and right corner portions of the vehicle body end surface. Since the thin-walled portion constituting the groove portion is provided at a constant interval, when one outer hood attempts to enter the other outer hood, the groove portion expands in the other outer hood, It deforms to absorb the shape difference, follows the mating shape, and an unreasonable load does not work. Therefore, durability is improved.
以下、本発明の実施の形態を図面に沿って説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.
図1は本発明に係る鉄道車両の連結用外幌の全体構成を示す説明図、図2は図1のC部拡大図、図3は図1のA−A線における断面図、図4は図1のB−B線における断面図である。   FIG. 1 is an explanatory diagram showing the overall configuration of a railroad car connecting outer hood according to the present invention, FIG. 2 is an enlarged view of a portion C in FIG. 1, FIG. 3 is a cross-sectional view taken along the line AA in FIG. It is sectional drawing in the BB line of FIG.
図1に示す外幌1は、後述するように断面U字形状で、鉄道車両の連結部において、前側車両の後端面又は後側車両の前端面に全周に亘って設けられ、後側車両の前端面又は前側車両の後端面に取り付けられる外幌に対向するように設けられる。よって、対向する前後の外幌1は弾性接触し、それらによって、前後車両間の空間部の全周が覆われ、前後車両間の内部空間と車両外の外部空間とが仕切られる。   The outer hood 1 shown in FIG. 1 has a U-shaped cross section as will be described later, and is provided on the rear end surface of the front vehicle or the front end surface of the rear vehicle over the entire circumference at the connecting portion of the railway vehicle. It is provided so as to face the outer hood attached to the front end face of the vehicle or the rear end face of the front vehicle. Therefore, the front and rear outer hoods 1 that are opposed to each other elastically contact each other, thereby covering the entire circumference of the space portion between the front and rear vehicles and partitioning the internal space between the front and rear vehicles and the external space outside the vehicle.
外幌1は、ほぼ水平方向に延び車体端面の上側縁付近に取り付けられる天井幌部材2と、ほぼ垂直方向に延び車体端面の左右側縁付近に取り付けられる左右側部幌部材3A,3Bと、それらの間を結合する湾曲した左右の肩幌部材4A,4Bと、左右の下側幌部材5A,5Bとで構成される。これらの大きさ(長さ)は、車両の相対動きを考慮して相対的に決定される。つまり、前後の外幌同士の当たる部位がずれても、相手方から無理な負荷を受けないように配慮している。なお、天井幌部材2は、中央部分が左右両端部分よりも幅広とされ、左右両端部分は、側部幌部材3A,3Bや肩幌部材4A,4Bと同じ幅とされている。また、前後の外幌について、それぞれの各幌部材2,3A,3B,4A,4Bの結合部分(切れ目)は長手方向においてずれた位置となるようにされ、結合部分同士が当たって早期に摩耗するのが回避される構成としている。   The outer hood 1 extends in a substantially horizontal direction and is attached to the vicinity of the upper edge of the vehicle body end surface, and the left and right side hood members 3A and 3B that extend in the substantially vertical direction and are attached to the vicinity of the left and right side edges of the vehicle body end surface. The left and right shoulder hood members 4A and 4B are connected to each other, and the left and right lower hood members 5A and 5B are connected to each other. These sizes (lengths) are relatively determined in consideration of the relative movement of the vehicle. In other words, even if the front and rear outer hoods are in contact with each other, care is taken not to receive an excessive load from the other party. In addition, the center part of the ceiling hood member 2 is wider than the left and right end portions, and the left and right end portions have the same width as the side hood members 3A and 3B and the shoulder hood members 4A and 4B. In addition, with respect to the front and rear outer hoods, the joint portions (cuts) of the respective hood members 2, 3A, 3B, 4A, 4B are shifted in the longitudinal direction, and the joint portions hit each other and wear quickly. It is set as the structure which avoids doing.
外幌1の前記各幌部材2,3A,3B,4A,4B,5A,5Bは、耐久性・耐候性・強度・柔軟性に優れる可撓性弾性シート材料を折り曲げて、断面U字形状に形成される 。
天井幌部材2、左右の側部幌部材3A,3B、肩幌部材4A,4B、左右の下側幌部材5A,5Bは、例えば天然ゴムベースまたはEPDM(エチレンプロピレンゴム)で配合された材料が用いられる。
The hood members 2, 3A, 3B, 4A, 4B, 5A, and 5B of the outer hood 1 are bent into a U-shaped section by bending a flexible elastic sheet material that is excellent in durability, weather resistance, strength, and flexibility. It is formed .
The ceiling hood member 2, left and right side hood members 3A and 3B, shoulder hood members 4A and 4B, and left and right lower hood members 5A and 5B are made of, for example, a natural rubber base or a material blended with EPDM (ethylene propylene rubber). Used.
天井幌部材2と肩幌部材4Aとの結合部分は、図2に示すように、天井幌部材2の端部に形成された嵌合凸部2Aが肩幌部材4Aの端部内に嵌合され、嵌合された状態で表面がほぼ面一となるように構成されている。嵌合凸部2Aは、図3において鎖線で示すように、肉厚が薄く形成され、嵌合部分(天井幌部材2(嵌合凸部2A)と肩幌部材4Aとの重なり合い部分)の剛性が高くならないように考慮されている。肩幌部材4A,4Bと天井幌部材2あるいは側部幌部材3A,3Bとの結合部分も同様に構成されている。   As shown in FIG. 2, a fitting convex portion 2A formed at the end portion of the ceiling hood member 2 is fitted into the end portion of the shoulder hood member 4A at the connecting portion between the ceiling hood member 2 and the shoulder hood member 4A. The surface is substantially flush with the mated state. As shown by the chain line in FIG. 3, the fitting convex portion 2A is formed with a small thickness, and the fitting portion (the overlapping portion of the ceiling hood member 2 (fitting convex portion 2A) and the shoulder hood member 4A) is rigid. Is considered not to be high. The joint portions between the shoulder hood members 4A and 4B and the ceiling hood member 2 or the side hood members 3A and 3B are also configured in the same manner.
天井幌部材2は、図3に示すように、湾曲した先端部2aと、車体端面(車体妻面)に取付具11を介して取り付けられる厚肉の外側(車体端面の外側縁側)及び内側(車体端面の車体中心側)基部2b,2cと、それらの間を連接する外側及び内側中間連接部2d,2eとを有し、断面U字形状に形成されている。そして、先端部2aは、前記内側基部2c寄りに偏倚して薄肉部分2aaが形成されている。つまり、先端部2aには、基部2b,2cの1/4程度の肉厚の薄肉部分2aaが、天井幌部材2の断面中心線に対して内側寄りに偏倚した位置に形成されている。外側及び内側中間連接部2d,2eは、厚肉の基部2b,2cから先端部2a(薄肉部分2aa)に向かって徐々に肉厚が薄くなるように形成されている。   As shown in FIG. 3, the ceiling hood member 2 includes a curved tip end portion 2 a, and a thick outer side (outer edge side of the end surface of the vehicle body) and inner side (attached to the end surface of the vehicle body via the fixture 11). The vehicle body end face is provided with base portions 2b and 2c and outer and inner intermediate connecting portions 2d and 2e connected to each other, and is formed in a U-shaped cross section. And the front-end | tip part 2a is biased toward the said inner base part 2c, and the thin part 2aa is formed. That is, a thin-walled portion 2aa having a thickness of about 1/4 of the base portions 2b and 2c is formed at the tip portion 2a at a position that is biased toward the inside with respect to the cross-sectional center line of the ceiling hood member 2. The outer and inner intermediate connecting portions 2d and 2e are formed so that the thickness gradually decreases from the thick base portions 2b and 2c toward the distal end portion 2a (thin portion 2aa).
取付金具11は、基部2b,2cの間隔を規制する断面コの字形状の第1の金具11Aと、この第1の金具11Aの外側部分11Aaとの間に外側基部2bを挟んで固定具12にて固定する第2の金具11Bと、第1の金具11Aの内側部分11Abと間にもう一方の内側基部2cを挟んで固定具13にて固定する第3の金具11Cとにより構成される。第1の金具11Aと、車体端面との間には、必要に応じてシール材14が充填される。この3つの金具11A〜11Cにて、天井幌部材2が断面U字形状に保持される。   The mounting bracket 11 is a fixture 12 having an outer base 2b sandwiched between a first bracket 11A having a U-shaped cross section that regulates the distance between the base portions 2b and 2c and an outer portion 11Aa of the first bracket 11A. And a third metal fitting 11C fixed by the fixing tool 13 with the other inner base portion 2c sandwiched between the inner part 11Ab of the first metal fitting 11A. A seal material 14 is filled between the first metal fitting 11A and the end surface of the vehicle body as necessary. The ceiling hood member 2 is held in a U-shaped cross section by the three metal fittings 11A to 11C.
一方、側部幌部材3A(3B)も、図4に示すように、湾曲した先端部3Aaと、車体端面に取付具16を介して取り付けられる厚肉の基部3Ab,3Acと、それらの間を連接する中間連接部3Ad,3Aeとを有し、断面U字形状に形成されているが、基部3Ab,3Acの取付間隔が天井幌部材11よりも狭く、80%程度とされている、また、先端部3Aa(湾曲部分)の半径が小さく、50%程度とされている。   On the other hand, as shown in FIG. 4, the side hood member 3A (3B) has a curved tip 3Aa, thick bases 3Ab and 3Ac attached to the end face of the vehicle body via a fixture 16, and a space between them. It has intermediate connecting parts 3Ad, 3Ae that are connected, and is formed in a U-shaped cross section, but the mounting interval of the base parts 3Ab, 3Ac is narrower than the ceiling hood member 11, about 80%. The radius of the tip 3Aa (curved portion) is small and is about 50%.
この側部幌部材3Aの取付金具16も、取付金具11と同様に、基部3Ab,3Acの間隔を規制する断面コの字形状の第1の金具16Aと、第1の金具16Aに外側部分16Aaとの間に基部を挟んで固定具17にて固定する第2の金具16Bと、第1の金具16Aの内側部分16Abと間にもう一方の基部を挟んで固定具18にて固定する第3の金具16Cとにより構成される。そして、基部3Ab,3Acの取付間隔を狭くするために、その取付間隔を狭くするだけ、第1の金具16の内側部分と外側部分との間隔が取付金具11より短くされている。   Similarly to the mounting bracket 11, the mounting bracket 16 of the side hood member 3A also has a first bracket 16A having a U-shaped cross section that regulates the distance between the base portions 3Ab and 3Ac, and an outer portion 16Aa on the first bracket 16A. A second metal fitting 16B that is fixed by a fixing tool 17 with a base portion interposed therebetween, and a third metal piece that is fixed by a fixing tool 18 with another base portion interposed between an inner portion 16Ab of the first metal fitting 16A. 16C. And in order to narrow the attachment space | interval of base 3Ab and 3Ac, the space | interval of the inner side part of the 1st metal fitting 16 and an outer side part is made shorter than the attachment metal fitting 11 only by making the attachment space | interval narrow.
また、肩幌部材4A(4B)の断面形状も、図5(a)(b)に示すように、湾曲した先端部4Aaと、車体端面に取付具(図示しない)を介して取り付けられる厚肉の基部4Ab,4Acと、それらの間を連接する中間連接部4Ad,4Aeとを有し、断面U字形状に形成され、基部4Ab,4Acの取付間隔が天井幌部材11よりも狭く先端部4Aaの半径が小さくされている(これは側部部幌部材3A(3B)と同様である)。そして、下側部分に一定間隔でもって、薄肉部分によって凹溝部4aが形成され、この凹溝部4aの溝間隔(開口部分の幅)が、肩幌部材4A自体の弾性によって薄肉部分が変形して変化できるようになっている。この凹溝部は、図5(c)に示す肩幌部材の凹溝部4a’のように、溝深さを浅くすることも可能である。また、天井幌部材2との結合部分付近において、外側部分にも、溝間隔が変化可能である凹溝部4bが形成されている。   Further, as shown in FIGS. 5 (a) and 5 (b), the cross-sectional shape of the shoulder hood member 4A (4B) is also a curved tip portion 4Aa and a thick wall attached to the end surface of the vehicle body via a fixture (not shown). 4Ab, 4Ac, and intermediate connecting portions 4Ad, 4Ae connecting them, formed in a U-shaped cross section, and the mounting interval between the base portions 4Ab, 4Ac is narrower than the ceiling hood member 11, and the tip portion 4Aa (This is similar to the side hood member 3A (3B)). Then, the groove portion 4a is formed by the thin portion with a constant interval in the lower portion, and the groove portion (width of the opening portion) of the groove portion 4a is deformed by the elasticity of the shoulder hood member 4A itself. Can change. It is possible to make the groove depth shallower as in the groove portion 4a 'of the shoulder hood member shown in FIG. Further, in the vicinity of the joint portion with the ceiling hood member 2, a concave groove portion 4b whose groove interval can be changed is also formed in the outer portion.
上記のように構成すれば、一方の外幌が他方の外幌に入ろうとすると、他方の外幌において、凹溝部4bの溝幅が広がり、一方の外幌との形状差を吸収するように変形し、相手形状に追従し、無理なく動作を続ける。   According to the above configuration, when one outer hood attempts to enter the other outer hood, the groove width of the recessed groove portion 4b widens in the other outer hood so as to absorb the shape difference from the one outer hood. Deforms, follows the shape of the other party, and continues to operate smoothly.

(ii)また、図7(a)〜(c)に示すように、肩幌部材4A”の内側部分から外側部分にかけて凹溝部4a”を形成することも可能である。この場合、外側部分に位置する凹溝部の部分は、変形していない状態では、凹溝部の開口部を閉じ、溝内部に埃が侵入したり空気抵抗となったりしないように構成される。そして、凹溝部4a”の開口部分が閉じている部分と開いている部分との境界は、図7(c)に示すようになっている。   (ii) Further, as shown in FIGS. 7A to 7C, it is also possible to form the groove 4a ″ from the inner part to the outer part of the shoulder hood member 4A ″. In this case, the concave groove portion located in the outer portion is configured so that the opening of the concave groove portion is closed and dust does not enter the groove or become air resistance when not deformed. Then, the boundary between the portion where the opening portion of the concave groove portion 4a ″ is closed and the open portion is as shown in FIG. 7C.
(iii)天井幌部材2と左右側部幌部材3A,3Bとを、同一断面形状の成形品で構成し、車体への取付部の幅を変えることで、それらの部材2,3A,3Bの先端部や取付部の断面形状を変更するようにしているが、予め、天井幌部材2、及び側部幌部材3A,3Bのそれぞれの部分にあった最適な形状に成形型を用いて成形し、それらを組立て製造することも可能である。   (iii) The ceiling hood member 2 and the left and right side hood members 3A and 3B are formed of molded products having the same cross-sectional shape, and by changing the width of the mounting portion to the vehicle body, the members 2, 3A and 3B The cross-sectional shape of the tip part and the mounting part is changed. However, it is molded in advance using a molding die into an optimum shape suitable for each part of the ceiling hood member 2 and the side hood members 3A and 3B. It is also possible to assemble and manufacture them.
