Description

本発明は、外板が、幕板パネル、吹寄せパネル、及び腰板パネルを有し、窓開口部が形成され、外板の車内面に車体高さ方向に沿って接合された縦骨部材と、外板の車内面に車体長手方向に沿って接合された横骨部材とを備える側構体を有する鉄道車両に関するものである。 In the present invention, the outer plate has a curtain plate panel, a blowing panel, and a waist plate panel, a window opening is formed, and a longitudinal bone member joined to the vehicle inner surface of the outer plate along the vehicle body height direction; The present invention relates to a railway vehicle having a side structure including a lateral bone member joined to a vehicle inner surface of an outer plate along a longitudinal direction of the vehicle body.

従来、通勤用鉄道車両の側構体においては、出入口開口部の間に窓開口部が形成されている。乗客荷重により車両全体がたわんだ時に、出入口開口部と窓開口部の間に形成されている吹寄せ部の強度が問題となる。吹寄せ部には、斜め方向に大きなせん断力が生じ、吹寄せ部が座屈する恐れがある。
吹寄せ部の座屈を防止するためには、特許文献１に記載されているように、吹寄せ部全体にシアプレートを接合して吹寄せ部の板厚を厚くすることにより強度を持たせる方法がある。 Conventionally, in a side structure of a commuter railcar, a window opening is formed between the entrance and exit openings. When the entire vehicle bends due to the passenger load, the strength of the blowing portion formed between the entrance opening and the window opening becomes a problem. A large shearing force is generated in the blowing portion in an oblique direction, and the blowing portion may be buckled.
In order to prevent buckling of the blowing part, as described in Patent Document 1, there is a method of giving strength by joining a shear plate to the entire blowing part and increasing the thickness of the blowing part. .

しかし、シアプレートを外板の車内面に溶接接合するには、全体的に接合強度を確保するため、シアプレートの全体に渡って溶接しなければならず、製造工程に時間がかかり問題であった。
その問題を解決するために、図１３に示すように、鉄道車両の側構体を構成する中間窓ブロック１００において、吹寄せパネル１０１の板厚を、幕板パネル１０２及び腰板パネル１０３の板厚より厚くすることを本出願人は、特許文献２で提案している。
一方、特許文献１には、吹寄せ部の強度を高めるために、吹寄せ部の外板の車内面に４本の横骨部材を接合することが記載されている。平板状の吹寄せ部を骨部材により分割することにより、座屈を防止するためである。 However, in order to weld and join the shear plate to the vehicle inner surface of the outer plate, it is necessary to weld the entire shear plate in order to ensure the overall joint strength, which is a problem because it takes time for the manufacturing process. It was.
In order to solve the problem, as shown in FIG. 13, in the intermediate window block 100 constituting the side structure of the railway vehicle, the thickness of the blowing panel 101 is thicker than the thickness of the curtain panel 102 and the waist panel 103. This applicant has proposed in Patent Document 2 to do this.
On the other hand, Patent Document 1 describes that four lateral bone members are joined to the inner surface of the outer plate of the blowing portion in order to increase the strength of the blowing portion. This is to prevent buckling by dividing the flat blowing portion by the bone member.

しかしながら、従来の通勤用鉄道車両には、次の問題があった。
（１）特許文献２では、吹寄せパネルの板厚が厚いため、吹寄せパネルと幕板パネルとに跨って、または吹寄せパネルと腰板パネルとに跨って縦骨部材を接合する場合に、段差があるため、縦骨部材のフランジに段差を設ける必要があり、製作工数が増加する問題があった。また、幕板パネルと腰板パネルにおいて、溶接によるひずみが外板の車外面に現れ鉄道車両の外観を悪くする問題があった。
特に、縦骨部材を溶接接合する場合には、側構体の側外板面に縦方向にひずみが現れる。外観においては、縦方向のひずみは目立つため、問題が大きい。 However, the conventional commuter railcar has the following problems.
(1) In patent document 2, since the plate | board thickness of a blowing panel is thick, when joining a longitudinal bone member straddling a blowing panel and a curtain board panel or straddling a blowing panel and a waist board panel, there exists a level | step difference. For this reason, it is necessary to provide a step on the flange of the longitudinal bone member, which increases the number of manufacturing steps. Further, in the curtain panel panel and the waist panel, there is a problem that distortion caused by welding appears on the outer surface of the outer panel and deteriorates the appearance of the railway vehicle.
In particular, when the longitudinal bone member is joined by welding, strain appears in the longitudinal direction on the side outer plate surface of the side structure. In appearance, the distortion in the vertical direction is conspicuous, which is a serious problem.

（２）特許文献１に記載されているように、吹寄せ部に骨部材を接合する場合に、吹寄せ部は縦方向に長く横方向に短いため、横骨部材を配置して接合する場合には、４本の横骨部材を必要とするため、部材の点数が増加し、余分な溶接工程を必要とする問題があった。
一方、吹寄せ部に縦骨部材を接合すれば、１本または２本の縦骨部材により必要な強度を確保できる。
しかし、特許文献２の鉄道車両において、縦骨部材を溶接しようとすると、段差があるため、縦骨部材のフランジに段差を設ける必要があり、製作工数が増加する問題があった。また、幕板パネルと腰板パネルにおいて、溶接によるひずみが外板の車外面に現れ鉄道車両の外観を悪くする問題があった。 (2) As described in Patent Document 1, when a bone member is joined to the blowing portion, the blowing portion is long in the vertical direction and short in the horizontal direction. Since four transverse bone members are required, the number of members increases and there is a problem that an extra welding process is required.
On the other hand, if a longitudinal bone member is joined to the blowing portion, the required strength can be ensured by one or two longitudinal bone members.
However, in the railway vehicle of Patent Document 2, when a longitudinal bone member is to be welded, there is a step, and therefore it is necessary to provide a step on the flange of the longitudinal bone member, which increases the number of manufacturing steps. Further, in the curtain panel panel and the waist panel, there is a problem that distortion caused by welding appears on the outer surface of the outer panel and deteriorates the appearance of the railway vehicle.

本発明は、上記問題点を解決するためのものであり、吹寄せパネルと幕板パネルとに跨って、または吹寄せパネルと腰板パネルとに跨って縦骨部材を接合する場合であっても、溶接によるひずみが外板の車外面に現れることがなく、横骨部材の点数を削減し、溶接工数を低減する鉄道車両を提供することを目的とする。 The present invention is for solving the above-described problems, even when the longitudinal bone member is joined across the blowing panel and the curtain panel panel, or across the blowing panel and the waist panel. An object of the present invention is to provide a railway vehicle in which the distortion caused by the above does not appear on the vehicle outer surface of the outer plate, the number of transverse bone members is reduced, and the number of welding steps is reduced.

上記課題を解決するために、本発明の鉄道車両は、次の構成を有している。
（１）外板が、幕板パネル、吹寄せパネル、及び腰板パネルを有し、窓開口部が形成され、外板の車内面に車体高さ方向に沿って接合された縦骨部材と、外板の車内面に車体長手方向に沿って接合された横骨部材とを備える側構体を有する鉄道車両において、吹寄せパネルの板厚が、幕板パネル及び腰板パネルの板厚より厚く形成されていること、窓開口部横の吹寄せ部の上方に位置する窓上横骨部材と、吹寄せ部の下方に位置する窓下横骨部材が、断面ハット型形状であり、外板の車内面に接する２つのフランジ部のうち、窓開口部側のフランジ部の長さが、他方のフランジ部の長さと比べて延長されていること、を特徴とする。 In order to solve the above problems, the railway vehicle of the present invention has the following configuration.
(1) The outer plate has a curtain plate panel, a blowing panel, and a waist plate panel, a window opening is formed, and a longitudinal bone member joined along the vehicle body height direction to the vehicle inner surface of the outer plate; In a railway vehicle having a side structure including a lateral frame member joined to the vehicle inner surface of the plate along the longitudinal direction of the vehicle body, the thickness of the blowing panel is formed to be thicker than the thickness of the curtain plate panel and the waist plate panel. That is, the upper horizontal bone member positioned above the blowing portion beside the window opening and the lower horizontal bone member positioned below the blowing portion have a hat-shaped cross section and are in contact with the inner surface of the outer plate 2. Of the two flange portions, the length of the flange portion on the window opening side is extended as compared with the length of the other flange portion.

（２）（１）に記載の鉄道車両において、延長されたフランジ部の板厚は、吹寄せパネルの板厚と、幕板パネル及び腰板パネルの板厚との差分であること、を特徴とする。 (2) In the railway vehicle according to (1), the plate thickness of the extended flange portion is a difference between the plate thickness of the blowing panel and the plate thickness of the curtain panel panel and the waist panel. .

（３）（１）または（２）に記載の鉄道車両において、吹寄せ部に配置される縦骨部材のフランジ部が、延長されたフランジ部を挟んで、外板の車内面に接合されていること、を特徴とする。
（４）（１）または（２）に記載の鉄道車両において、吹寄せ部に配置される横骨部材のフランジ部が、延長されたフランジ部を挟んで、外板の車内面に接合されていること、を特徴とする。 (3) In the railway vehicle according to (1) or (2), the flange portion of the longitudinal bone member disposed in the blowing portion is joined to the vehicle inner surface of the outer plate with the extended flange portion interposed therebetween. It is characterized by this.
(4) In the railway vehicle according to (1) or (2), the flange portion of the lateral bone member disposed in the blowing portion is joined to the vehicle inner surface of the outer plate with the extended flange portion interposed therebetween. It is characterized by this.

本発明の鉄道車両は、次のような作用、効果を奏する。
（１）外板が、幕板パネル、吹寄せパネル、及び腰板パネルを有し、窓開口部が形成され、外板の車内面に車体高さ方向に沿って接合された縦骨部材と、外板の車内面に車体長手方向に沿って接合された横骨部材とを備える側構体を有する鉄道車両において、吹寄せパネルの板厚が、幕板パネル及び腰板パネルの板厚より厚く形成されていること、窓開口部横の吹寄せ部の上方に位置する窓上横骨部材と、吹寄せ部の下方に位置する窓下横骨部材が、断面ハット型形状であり、外板の車内面に接する２つのフランジ部のうち、窓開口部側のフランジ部の長さが、他方のフランジ部の長さと比べて延長されていること、を特徴とするので、窓上横骨部材の窓開口部側（下側）に延設されたフランジ部と、窓下横骨部材の窓開口部側（上側）に延設されたフランジ部が、吹寄せ部に配置された縦骨部材または横骨部材と側構体の外板との間に装着されるため、吹寄せパネルと幕板パネルとに跨って、または吹寄せパネルと腰板パネルとに跨って縦骨部材または横骨部材を接合する場合に、溶接によるひずみが外板の車外面に現れることがなく、鉄道車両の外観を悪くすることがない。 The railway vehicle of the present invention has the following operations and effects.
(1) The outer plate has a curtain plate panel, a blowing panel, and a waist plate panel, a window opening is formed, and a longitudinal bone member joined along the vehicle body height direction to the vehicle inner surface of the outer plate; In a railway vehicle having a side structure including a lateral frame member joined to the vehicle inner surface of the plate along the longitudinal direction of the vehicle body, the thickness of the blowing panel is formed to be thicker than the thickness of the curtain plate panel and the waist plate panel. That is, the upper horizontal bone member positioned above the blowing portion beside the window opening and the lower horizontal bone member positioned below the blowing portion have a hat-shaped cross section and are in contact with the inner surface of the outer plate 2. Of the two flange portions, the length of the flange portion on the window opening side is extended as compared with the length of the other flange portion. (Lower side) extended to the flange part and the window opening side (upper side) of the lower horizontal bone member Since the flange portion is mounted between the longitudinal bone member or the lateral bone member arranged in the blowing portion and the outer plate of the side structure, it straddles the blowing panel and the curtain plate panel, or the blowing panel and the waist plate. When joining a longitudinal bone member or a transverse bone member straddling a panel, distortion due to welding does not appear on the outer surface of the outer plate, and the appearance of the railway vehicle is not deteriorated.

（２）（１）に記載の鉄道車両において、延長されたフランジ部の板厚は、吹寄せパネルの板厚と、幕板パネル及び腰板パネルの板厚との差分であること、を特徴とするので、吹寄せパネルと幕板パネルとの段差、及び吹寄せパネルと腰板パネルとの段差を確実になくすことができるため、縦骨部材のフランジに段差を設ける必要がない。
また、別部材を必要としないため、製造工程において、余分な作業が不要であり、作業効率を高くすることができ、コストダウンすることができる。 (2) In the railway vehicle according to (1), the plate thickness of the extended flange portion is a difference between the plate thickness of the blowing panel and the plate thickness of the curtain panel panel and the waist panel. Therefore, the step between the blowing panel and the curtain panel and the step between the blowing panel and the waistboard panel can be eliminated with certainty, so there is no need to provide a step on the flange of the longitudinal bone member.
Further, since no separate member is required, no extra work is required in the manufacturing process, work efficiency can be increased, and costs can be reduced.

（３）（１）または（２）に記載の鉄道車両において、吹寄せ部に配置される縦骨部材のフランジ部が、延長されたフランジ部を挟んで、外板の車内面に接合されていること、を特徴とするので、１本の縦骨部材だけで吹寄せ部の座屈強度を十分高めることができるため、骨部材の点数を減少させることができる。また、延設されたフランジ部は、吹寄せ部に当接させた状態で、縦骨部材のフランジ部と外板車内面の間に保持されるため、縦骨部材のフランジ部と外板の車内面との間に隙間を極力少なくでき、溶接によるひずみを減少することができる。
特に、縦骨部材を溶接接合する場合には、側構体の側外板面に縦方向にひずみが現れるが、本発明によれば、縦方向のひずみも発生しないため、外観を美しく保つことができる。 (3) In the railway vehicle according to (1) or (2), the flange portion of the longitudinal bone member disposed in the blowing portion is joined to the vehicle inner surface of the outer plate with the extended flange portion interposed therebetween. Since the buckling strength of the blowing portion can be sufficiently increased with only one longitudinal bone member, the number of bone members can be reduced. Further, since the extended flange portion is held between the flange portion of the longitudinal bone member and the inner surface of the outer plate wheel in a state of being in contact with the blowing portion, the flange portion of the longitudinal bone member and the interior of the outer plate are inside the vehicle. The gap between the surfaces can be reduced as much as possible, and distortion caused by welding can be reduced.
In particular, when welding longitudinal bone members, distortion appears in the vertical direction on the side outer plate surface of the side structure, but according to the present invention, no distortion in the vertical direction is generated, so that the appearance can be kept beautiful. it can.

（４）（１）または（２）に記載の鉄道車両において、吹寄せ部に配置される横骨部材のフランジ部が、延長されたフランジ部を挟んで、外板の車内面に接合されていること、を特徴とするので、吹寄せパネルと幕板パネルとに跨って、または吹寄せパネルと腰板パネルとに跨って横骨部材を接合する場合に、溶接によるひずみが外板の車外面に現れることがなく、鉄道車両の外観を悪くすることがない。また、吹寄せパネルと幕板パネル、及び吹寄せパネルと腰板パネルの溶接接合部の強度を高めることができる。 (4) In the railway vehicle according to (1) or (2), the flange portion of the lateral bone member disposed in the blowing portion is joined to the vehicle inner surface of the outer plate with the extended flange portion interposed therebetween. Therefore, when a horizontal bone member is joined across the blowing panel and the curtain panel, or across the blowing panel and the waist panel, distortion due to welding appears on the outer surface of the outer plate. There will be no deterioration in the appearance of the railway vehicle. Moreover, the strength of the welded joint between the blowing panel and the curtain panel and between the blowing panel and the waist panel can be increased.

＜第１実施形態＞
本発明の鉄道車両の第１の実施形態について、図面を参照しながら以下に詳細に説明する。図１は、本発明の実施形態に係る鉄道車両の側構体１の一部の内面を示す図である。図２は、側構体１の外板を示す図である。図３は、図１のＡＡ拡大断面図である。
図１に示すように、出入口開口部６と窓開口部５との間に吹寄せ部を構成する吹寄せパネル２が形成されている。図２に示すように、吹寄せパネル２の上部には、幕板パネル３がレーザ溶接により接合されており、吹寄せパネル２の下部には、腰板パネル４がレーザ溶接により接合されている（以下、溶接接合は、レーザ溶接による接合を示す）。側構体１の外板は、吹寄せパネル２、幕板パネル３、腰板パネル４から構成される。
吹寄せパネル２は、ステンレス製で板厚が３．５ｍｍの板である。幕板パネル３と腰板パネル４は、ステンレス製で板厚が２．０ｍｍの板である。吹寄せパネル２、幕板パネル３、及び腰板パネル４は、図３に示すように、車外面が平面になるように、溶接接合されているため、車内面では、１．５ｍｍの段差が存在する。 <First Embodiment>
A first embodiment of a railway vehicle according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a diagram showing an inner surface of a part of a side structure 1 of a railway vehicle according to an embodiment of the present invention. FIG. 2 is a view showing the outer plate of the side structure 1. FIG. 3 is an AA enlarged sectional view of FIG.
As shown in FIG. 1, a blowing panel 2 that forms a blowing portion is formed between an entrance / exit opening 6 and a window opening 5. As shown in FIG. 2, the curtain panel 3 is joined to the upper part of the blowing panel 2 by laser welding, and the waist panel 4 is joined to the lower part of the blowing panel 2 by laser welding (hereinafter, referred to as “laser panel panel 4”). Welding refers to joining by laser welding). The outer plate of the side structure 1 includes a blowing panel 2, a curtain plate panel 3, and a waist plate panel 4.
The blowing panel 2 is a plate made of stainless steel and having a thickness of 3.5 mm. The curtain panel 3 and the waist panel 4 are made of stainless steel and have a thickness of 2.0 mm. As shown in FIG. 3, the blowing panel 2, the curtain panel panel 3, and the waist panel 4 are welded so that the outer surface of the vehicle becomes a flat surface, and therefore there is a step of 1.5 mm on the inner surface of the vehicle. .

図１に示すように、幕板パネル３には、４本の断面ハット型形状の横骨部材が側構体１の長手方向に平行に配置され、幕板パネル３の車内面に溶接接合されている。複数の横骨部材のうち、窓開口部側（窓開口部５の水平方向中心線側）に最も近接して、窓上横骨部材１１が配置されている。
腰板パネル４には、４本の断面ハット型形状の横骨部材が側構体１の長手方向に平行に配置され、腰板パネル４の車内面に溶接接合されている。複数の横骨部材のうち、窓開口部側（窓開口部５の水平方向中心線側）に最も近接して、窓下横骨部材１２が配置されている。
また、吹寄せパネル２には、１本の縦骨部材２０が配置され、吹寄せパネル２の車内面に溶接接合されている。 As shown in FIG. 1, four cross-hat-shaped transverse bone members are arranged on the curtain panel 3 in parallel with the longitudinal direction of the side structure 1 and welded to the inner surface of the curtain panel 3. Yes. Among the plurality of horizontal bone members, the on-window horizontal bone member 11 is disposed closest to the window opening side (the horizontal center line side of the window opening 5).
On the lumbar panel 4, four transverse bone members having a hat-shaped cross section are arranged in parallel to the longitudinal direction of the side structure 1 and are welded to the inner surface of the lumbar panel 4. Of the plurality of transverse bone members, the under-window transverse bone member 12 is disposed closest to the window opening side (the horizontal center line side of the window opening 5).
In addition, one vertical bone member 20 is disposed on the blowing panel 2 and is welded to the vehicle inner surface of the blowing panel 2.

次に、窓上横骨部材１１の構造を説明する。図３に示すように、吹寄せパネル２と幕板パネル３とは、車外面（図中右側面）が平面となるように溶接接合されているため、車内面には、１．５ｍｍの段差がある。したがって、縦骨部材２０のフランジ部２０ａの底面と幕板パネル３の車内面との間には、１．５ｍｍの隙間が形成されている。
窓上横骨部材１１は、断面がハット型形状であり、ハット部１１ｂの両側には、第１フランジ部１１ａと第２フランジ部１１ｃが延設されている。第１フランジ部１１ａは、窓開口部側（窓開口部５の水平方向中心線側）に延設されている。 Next, the structure of the on-window horizontal bone member 11 will be described. As shown in FIG. 3, the blowing panel 2 and the curtain panel 3 are welded so that the outer surface of the vehicle (the right side surface in the figure) is a flat surface, so that a step of 1.5 mm is formed on the inner surface of the vehicle. is there. Therefore, a gap of 1.5 mm is formed between the bottom surface of the flange portion 20 a of the longitudinal bone member 20 and the vehicle inner surface of the curtain panel 3.
The upper horizontal bone member 11 has a hat-shaped cross section, and a first flange portion 11a and a second flange portion 11c are extended on both sides of the hat portion 11b. The first flange portion 11a extends to the window opening side (the horizontal center line side of the window opening 5).

ここで、第１フランジ部１１ａの長さは、第２フランジ部１１ｃの長さと比べて長く構成され、第１フランジ部１１ａの端面は、吹寄せパネル２の端面近くまで延設されている。
以上、窓上横骨部材１１について説明したが、窓下横骨部材１２の構造は、第１フランジ部１２ａが、第１フランジ部１１ａと同様に、窓開口部側（窓開口部５の水平方向中心線側）に延設されているため、図中上向きに延設されている点が相違するのみで、基本的に窓上横骨部材１１の構造と同じであるので詳細な説明を割愛する。 Here, the length of the 1st flange part 11a is comprised long compared with the length of the 2nd flange part 11c, and the end surface of the 1st flange part 11a is extended to near the end surface of the blowing panel 2. FIG.
As mentioned above, although the horizontal bone member 11 on a window was demonstrated, as for the structure of the horizontal bone member 12 below a window, the 1st flange part 12a is the window opening part side (horizontal of the window opening part 5 similarly to the 1st flange part 11a). Since it is extended in the direction center line side), it is basically the same as the structure of the horizontal bone member 11 on the window, except that it is extended upward in the figure. To do.

縦骨部材２０の両側のフランジ部２０ａ、２０ｃの下面は、第１フランジ部１１ａの上面に接触した状態で溶接接合されるため、幕板パネル３にひずみが発生することがなく、幕板パネル３の車外面にひずみが現れることがない。吹寄せパネル２は、３．５ｍｍと厚く構成されているため、車外面にひずみが現れることは少なく、従来、ひずみは主に幕板パネル３の車外面に現れていた。
縦骨部材２０のハット部２０ｂの上面は延長され延設上面２０ｄを形成している。延設上面２０ｄは、窓上横骨部材１１のハット部１１ｂの上面に溶接接合される。縦骨部材２０のハット部２０ｂの両側面部には、切欠部２０ｅが形成されている。 Since the lower surfaces of the flange portions 20a and 20c on both sides of the vertical bone member 20 are welded and joined in contact with the upper surface of the first flange portion 11a, the curtain plate panel 3 is not distorted, and the curtain plate panel. No distortion appears on the vehicle outer surface. Since the blowing panel 2 is configured to be as thick as 3.5 mm, distortion hardly appears on the outer surface of the vehicle, and conventionally, the distortion has mainly appeared on the outer surface of the curtain panel 3.
The upper surface of the hat portion 20b of the longitudinal bone member 20 is extended to form an extended upper surface 20d. The extended upper surface 20d is welded to the upper surface of the hat portion 11b of the on-window horizontal bone member 11. Cutout portions 20e are formed on both side portions of the hat portion 20b of the longitudinal bone member 20.

＜第２実施形態＞
次に、本発明の第２の実施形態について説明する。図４は、鉄道車両の側構体１の一部の内面を示す図である。図５は、図４のＢＢ拡大断面図である。
第２の実施形態は、概ね第１の実施形態と同じ部分が多いので、異なる点のみ詳細に説明し、同じ部分については説明を割愛する。
図４に示すように、吹寄せパネル２の上部及び下部には、各々横骨部材１３が溶接接合されている。横骨部材１３は、断面がハット型形状であり、ハット部１３ｂの両側には、第１フランジ部１３ａと第２フランジ部１３ｃが延設されている。縦骨部材２１は、吹寄せパネル２の上下に配置された横骨部材１３の間に配置され溶接接合されている。縦骨部材２１は、断面がハット型形状であり、ハット部２１ｂの両側には、第１フランジ部２１ａ、２１ｃが延設されている。ハット部２１ｂの上面は延長され延設上面２１ｄを形成している。延設上面２１ｄは、横骨部材１３のハット部１３ｂの上面に溶接接合される。ハット部２１ｂの両側面部には、切欠部２１ｅが形成されている。
図５に示すように、窓上横骨部材１１の第１フランジ部１１ａは、第２フランジ部１１ｃと比べて長く延設されており、吹寄せパネル２の端面近くまで延設されている。
これにより、横骨部材１３の一方の第２フランジ部１３ｃは、窓上横骨部材１１の第１フランジ部１１ａの上面に接する状態で溶接接合されるため、幕板パネル３にひずみが発生することがなく、幕板パネル３の車外面にひずみが現れることがない。また、吹寄せパネル２と幕板パネル３、及び吹寄せパネル２と腰板パネル４の溶接接合部の強度を高めることができる。 Second Embodiment
Next, a second embodiment of the present invention will be described. FIG. 4 is a view showing an inner surface of a part of the side structure 1 of the railway vehicle. FIG. 5 is an enlarged cross-sectional view of BB in FIG.
Since the second embodiment has many parts that are generally the same as those of the first embodiment, only different points will be described in detail, and description of the same parts will be omitted.
