　この構造として従来、例えば、図２９乃至図３１に示すように、連結された一方の車体１０１の妻面１０２と他方の車体１０３の妻面１０４間に通路１０５を構成する内幌１０６を架設し、図３０または図３１の該内幌１０６の左右の両側に、内幌１０６と離間して、一方の車体１０１の妻面１０２からＵ字状に突設した可撓性を有する一方の外幌１０７と、他方の車体１０３の妻面１０４からＵ字状に突設した可撓性を有する他方の外幌１０８を設け、これらの先部を図２９、図３１に示すように、相互に対向接触させている。 Conventionally, as this structure, for example, as shown in FIGS. 29 to 31, an inner hood 106 that constitutes a passage 105 is constructed between the end face 102 of one connected body 101 and the end face 104 of the other body 103. 30 or 31, one flexible outer hood that is spaced apart from the inner hood 106 and protrudes in a U-shape from the end face 102 of one vehicle body 101 on the left and right sides of the inner hood 106. 107 and the other flexible outer hood 108 projecting in a U-shape from the end face 104 of the other vehicle body 103, and these front portions are opposed to each other as shown in FIG. 29 and FIG. It is in contact.
　そして、この外幌１０７は、図３０に示すように、車体１０１の左右側面である略直立部、すなわち、妻面の側部１１１に沿った範囲のみに設けられ、妻面１０２の肩部（車体の肩部）１１２と屋根部１１３に沿った部分には設けられていない。これは、図示されていないが、他方の外幌１０８でも同様である。 As shown in FIG. 30, the outer hood 107 is provided only in a substantially upright portion that is the left and right side surfaces of the vehicle body 101, that is, only in a range along the side portion 111 of the wife surface, and the shoulder portion ( It is not provided in a portion along the shoulder portion 112 of the vehicle body and the roof portion 113. Although not shown, this is the same for the other outer hood 108.
　このような外幌１０７、１０８においては、連結部空間１１４内から車体の左右方向への騒音の放射は抑制されるが、連結部空間１１４内からの騒音が肩部１１２の開放部１１５を通じて矢印Ｋのように外部へ放射され車外への影響を与える。 In such outer hoods 107 and 108, noise emission in the left-right direction of the vehicle body from inside the connecting portion space 114 is suppressed, but noise from inside the connecting portion space 114 is indicated by an arrow through the opening 115 of the shoulder portion 112. Like K, it is radiated to the outside and affects the outside of the vehicle.
　また、屋根側の開放部１１６からも矢印Ｌのように発生された騒音が放射されるが、これらの騒音の放射を抑制することが好ましい。 Further, although noise generated as indicated by an arrow L is radiated from the open portion 116 on the roof side, it is preferable to suppress radiation of these noises.
　そこで、従来、前記の外幌１０７、１０８を、車体の妻面における左右両側に配置するのみではなく、図３２に示すように、略垂直の側幌部２００の上部を延長して、前記妻面（車体）の肩部１１２において、外側へ膨出する湾曲状の肩幌部２０１を延設し、かつ、屋根縁に沿った屋根側幌部２０２を延設して前記妻面の肩部１１２の開放部１１５及び屋根側の開放部１１６からの騒音低減を図るものが特許文献１に知られている。 Therefore, conventionally, the outer hoods 107 and 108 are not only disposed on both the left and right sides of the body surface of the vehicle body, but also as shown in FIG. In the shoulder 112 of the surface (vehicle body), a curved shoulder hood portion 201 bulging outward is extended, and a roof side hood portion 202 is extended along the roof edge to extend the shoulder portion of the wife surface. Patent Document 1 discloses a technique for reducing noise from the opening portion 115 of 112 and the opening portion 116 on the roof side.

　次に、前記左側幌９の断面形状について図４乃至図８により詳述する。
　図４に示す左側幌９の側幌部１３の横断面形状（Ｂ－Ｂ線断面）は、図５に示すように、基端側に開口部２０を有するＵ字状に形成されている。すなわち、所定の間隔を有して平行に配置した板状の内側基部２１と板状の外側基部２２と、該両基部２１、２２の先を連結する先細状（図の実施例では略半円状）の先部２３とからなる。また、両基部２１、２２は、これを妻面に付設した際に、その妻面からの突出状態を保持するために剛性が大きく可撓性の小さい厚肉Ｔ１に形成され、先部２３は、両基部２１、２２より薄肉Ｔ２に形成され、該先部２３が両基部２１、２２に比べて剛性が小さく可撓性を大きくして形成されている。また、基部２１、２２から先部２３への連結部２４は、肉厚が漸減するように形成されている。 Next, the cross-sectional shape of the left hood 9 will be described in detail with reference to FIGS.
The cross-sectional shape (cross-sectional view taken along the line BB) of the side hood portion 13 of the left hood 9 shown in FIG. 4 is formed in a U shape having an opening 20 on the base end side, as shown in FIG. That is, a plate-like inner base portion 21 and a plate-like outer base portion 22 arranged in parallel with a predetermined interval, and a tapered shape connecting the tips of both the base portions 21 and 22 (substantially semicircular in the illustrated embodiment). Shape) tip portion 23. Moreover, both base parts 21 and 22 are formed in the thick wall T1 which is large in rigidity and small in flexibility in order to maintain the protruding state from the wife face when it is attached to the wife face. The base 23 is formed to be thinner T2 than the bases 21 and 22, and the tip 23 is formed with lower rigidity and greater flexibility than the bases 21 and 22. Moreover, the connection part 24 from the base parts 21 and 22 to the front part 23 is formed so that wall thickness may decrease gradually.
　前記上幌部１５の横断面形状（図４のＢ－Ｂ線断面）は、前記側幌部１３の図５に示す横断面形状（図４のＢ－Ｂ線断面）と同様に、妻面に固定される内側基部２１と外側基部２２とこれらの先を連結した先部２３とでＵ字状に形成した形状であり、その肉厚も同様に形成されているか、これらの肉厚、形状等の寸法は妻面の構造で異なることもある。 The cross-sectional shape of the upper hood part 15 (cross-sectional line BB in FIG. 4) is the same as the cross-sectional shape of the side hood part 13 shown in FIG. 5 (cross-sectional line BB in FIG. 4). The inner base portion 21 and the outer base portion 22 that are fixed to each other and the tip portion 23 that connects these tips are formed in a U-shape, and the thickness thereof is also formed in the same manner, or these thicknesses and shapes The dimensions such as may differ depending on the structure of the end face.
　前記肩幌部１７の横断面形状（図４のＣ－Ｃ線断面）は、図６に示すように、基端側に開口部２０を有するＵ字状に形成され、その外周形状は前記図５に示す側幌部１３の外周形状と同一形状である。また、その板状の内側基部２１ａと板状の外側基部２２ａの肉厚は、前記図５に示す側幌部１３の先部２３の肉厚Ｔ２と同等に形成され、更に、その先部２３ａの肉厚は、前記図５の先部２３の肉厚Ｔ２と同等に形成されている。すなわち、肩幌部１７における内側基部２１ａと外側基部２２ａと先部２３ａの肉厚Ｔ２は前記側幌部１３、上幌部１５の内側基部２１と外側基部２２の肉厚Ｔ１よりも薄く形成されている。したがって、肩幌部１７における図４に示す湾曲部Ｒ全体が薄肉に形成され、側幌部１３、上幌部１５よりも可撓性が大きくなっている。 As shown in FIG. 6, the cross-sectional shape of the shoulder hood portion 17 (cross-sectional view taken along the line CC in FIG. 4) is formed in a U shape having an opening 20 on the base end side, and the outer peripheral shape thereof is 5 is the same shape as the outer periphery of the side hood part 13 shown in FIG. Further, the thickness of the plate-like inner base portion 21a and the plate-like outer base portion 22a is formed to be equal to the thickness T2 of the tip portion 23 of the side hood portion 13 shown in FIG. 5, and further, the tip portion 23a. Is formed to be equivalent to the thickness T2 of the tip 23 in FIG. That is, the thickness T2 of the inner base portion 21a, the outer base portion 22a, and the tip portion 23a in the shoulder hood portion 17 is formed thinner than the thickness T1 of the side hood portion 13, the inner hood portion 21 of the upper hood portion 15, and the outer base portion 22. ing. Therefore, the entire curved portion R shown in FIG. 4 in the shoulder hood portion 17 is formed thin, and is more flexible than the side hood portion 13 and the upper hood portion 15.
　また、肩幌部１７における両側基部２１ａ、２２ａから側幌部１３及び上部幌１５への連結部２５の基部の肉厚は、図８に示すように、漸増している。 Further, the thickness of the base portion of the connecting portion 25 from the both side base portions 21a and 22a to the side hood portion 13 and the upper hood 15 in the shoulder hood portion 17 is gradually increased as shown in FIG.
　また、前記右側幌１０の側幌部１３、肩幌部１７、上部幌１５も前記左側幌９の側幌部１３、肩幌部１７、上部幌１５と同様の構造であるため、その説明は省略する。 Further, since the side hood part 13, shoulder hood part 17, and upper hood 15 of the right hood 10 have the same structure as the side hood part 13, shoulder hood part 17 and upper hood 15 of the left hood 9, the explanation thereof is as follows. Omitted.
　次に、車体１の妻面２に対する前記左側幌９と右側幌１０の取付構造を図９乃至図１１により説明する。 Next, the attachment structure of the left hood 9 and the right hood 10 to the end face 2 of the vehicle body 1 will be described with reference to FIGS.

A curved member 50 is fixed by a bolt 51 so as to bulge outward from 5a toward the outer bases 22 and 22a.
　前記実施例１においては、前記の構成により、次のような作用、効果を発揮する。
　両車体１、４に付設された両外幌８、８Ａの先部が相互に接触することにより、両車体１、４間の連結部空間の外周部が両外幌８、８Ａで被覆され、車両走行中における連結部空間内の騒音の側方への放射は側幌部１３で抑制され、車体肩部からの斜め上方への放射は肩幌部１７で抑制され、上方への放射は上幌部１５及び屋根側幌１１で抑制される。 In the said Example 1, the following effect | actions and effects are exhibited by the said structure.
When the front portions of both outer hoods 8 and 8A attached to both the vehicle bodies 1 and 4 are in contact with each other, the outer peripheral portion of the connecting portion space between the both vehicle bodies 1 and 4 is covered with both outer hoods 8 and 8A. Radiation of the noise in the connecting part space while the vehicle is running to the side is suppressed by the side hood part 13, radiation upward from the shoulder of the vehicle body is suppressed by the shoulder hood part 17, and upward radiation is the top. It is suppressed by the hood part 15 and the roof side hood 11.
　したがって、本実施例１においては、前記図２９乃至図３１に示す従来の外幌１０７、１０８において発生していた妻面の肩部からの騒音の放射（図３０の矢印Ｋ方向の放射）を抑制できる。また、上部幌１５及び屋根側幌１１を設けたことにより、上方への騒音の放射を抑制できる。 Therefore, in the first embodiment, the noise radiation (radiation in the direction of arrow K in FIG. 30) generated from the shoulder portion of the wife surface, which was generated in the conventional outer hoods 107 and 108 shown in FIGS. Can be suppressed. Further, by providing the upper hood 15 and the roof side hood 11, it is possible to suppress upward noise emission.
　次に、車両走行中において、両外幌８、８Ａが押し付けあった状態で相対的に変位すると、側幌部１３と上幌部１５及び屋根側幌１１は、これらが略直線状であるため、内側又は外側へ容易に変位し、しわの発生が少なく亀裂の発生も少ない。 Next, when the two outer hoods 8 and 8A are relatively displaced while the vehicle is running, the side hood portion 13, the upper hood portion 15 and the roof side hood 11 are substantially straight. , Easily displaced inward or outward, less wrinkle generation and less cracking.
　また、肩幌部１７においては、該肩幌部１７の内側基部２１ａと外側基部２２ａの肉厚を、側幌部１３、上幌部１５の内側基部２１と外側基部２２の肉厚よりも薄くし、かつ、先部２３ａの肉厚も薄くしたので、該肩幌部１７における内周部の変形が容易になり、肩幌部１７での剛性が小さくなり、柔軟に変形できる。そのため、両外幌８、８Ａの押付け状態での変位に際して、該肩幌部１７が容易に変形し、発生するしわが少なくなるとともに小さくなり、該肩幌部１７での亀裂の発生を低減できる。 In the shoulder hood part 17, the thickness of the inner base part 21 a and the outer base part 22 a of the shoulder hood part 17 is thinner than the thickness of the side hood part 13 and the inner base part 21 and the outer base part 22 of the upper hood part 15. In addition, since the thickness of the tip portion 23a is reduced, the inner periphery of the shoulder hood portion 17 is easily deformed, the rigidity at the shoulder hood portion 17 is reduced, and the shoulder hood portion 17 can be flexibly deformed. Therefore, when the outer hoods 8 and 8A are displaced in the pressed state, the shoulder hood portion 17 is easily deformed, the generated wrinkles are reduced and reduced, and the occurrence of cracks in the shoulder hood portion 17 can be reduced. .
　前記実施例１では屋根側幌１１を設けたが、図１３、図１４、図１５に示すように、前記屋根側幌１１を設けず、前記左側幌９及び右側幌１０のみで外幌を構成しても良い。 In the first embodiment, the roof side hood 11 is provided. However, as shown in FIGS. 13, 14, and 15, the roof hood 11 is not provided, and only the left hood 9 and the right hood 10 constitute an outer hood. You may do it.
　なお、本実施例２の左側幌９及び右側幌１０の形状、材質、妻面への取付構造は前記実施例１と同様であるため、前記と同一の部分には前記実施例と同一の符号を付してその説明を省略する。 The shape, material, and mounting structure of the left hood 9 and right hood 10 of the second embodiment are the same as those of the first embodiment, and the same parts as those described above are denoted by the same reference numerals as those of the first embodiment. The description is omitted.
　本実施例２においては、前記実施例１と比べて、屋根側幌１１が存在しないため、図１４の直上の開口された上部４００から騒音が発生するが、左右側幌９、１０の側幌部１３、肩幌部１７、上幌部１５が存在することにより、車体間の連結部から騒音が側方及び斜め上方へ放射されることを抑制できる。 In the second embodiment, compared to the first embodiment, since the roof side hood 11 does not exist, noise is generated from the opened upper portion 400 in FIG. By the presence of the portion 13, the shoulder hood portion 17, and the upper hood portion 15, it is possible to suppress noise from being radiated sideways and obliquely upward from the connecting portion between the vehicle bodies.
　車体間の連結部の騒音が直上からの騒音であれば車外への影響は少ないため、本実施例２においても騒音対策として有効である。 If the noise at the connecting part between the vehicle bodies is noise from directly above, there is little influence on the outside of the vehicle, so this embodiment 2 is also effective as a noise countermeasure.
