Description

本発明は鉄道車両の側構体に関し、特に幕板等の製作誤差の影響を受け難くすることができ、組立作業性を向上できる鉄道車両の側構体に関するものである。   The present invention relates to a side structure of a railway vehicle, and more particularly to a side structure of a railway vehicle that can be hardly affected by manufacturing errors such as curtains and can improve assembly workability.

骨部材と外板とが接合されて構成される鉄道車両の側構体として、例えば特許文献１や特許文献２に開示されるものが知られている。特許文献１等に開示される鉄道車両の側構体は、幕板、吹寄板および腰板を接合することにより組立てられる。幕板は、入口開口部を開閉するドアユニット間の長さを有し、ドアユニットの両側に両端が接合される。   As a side structure of a railway vehicle configured by joining a bone member and an outer plate, those disclosed in, for example, Patent Document 1 and Patent Document 2 are known. The side structure of a railway vehicle disclosed in Patent Document 1 and the like is assembled by joining a curtain plate, a blowing plate, and a waist plate. The curtain plate has a length between door units that open and close the entrance opening, and both ends are joined to both sides of the door unit.

しかしながら上記従来の技術では、幕板の両端がドアユニットの両側に接合されることで側構体の上部側が作られるので、側構体の上部側の車長方向の完成寸法を調整し難いという問題があった。   However, in the above-mentioned conventional technology, since the upper side of the side structure is made by joining both ends of the curtain plate to both sides of the door unit, there is a problem that it is difficult to adjust the completed dimension in the vehicle length direction on the upper side of the side structure. there were.

ところで、鉄道車両の側構体を組立てるときには、キャンバーと呼ばれる上向きの反りを設け、弓なりの形状にする。これは、車体に取り付けられる各種機器や乗客の荷重により車両が撓んでも、強度低下を起こさないようにすると共に車両の底部が限界寸法を超えないようにするためである。キャンバーを設けるには、側構体の上部側の車長方向の完成寸法を、側構体の下部側の車長方向の完成寸法より僅かに長くする必要がある。   By the way, when assembling the side structure of a railway vehicle, an upward warp called a camber is provided to form a bow shape. This is to prevent the strength from being lowered even when the vehicle is bent by the load of various devices or passengers attached to the vehicle body, and to prevent the bottom of the vehicle from exceeding the critical dimension. In order to provide the camber, it is necessary to make the completed dimension in the vehicle length direction on the upper side of the side structure slightly longer than the completed dimension in the vehicle length direction on the lower side of the side structure.

ところが上記従来の技術では、側構体の車長方向の完成寸法を調整し難いので、幕板等の製作誤差の影響を受けて、完成寸法の精度を向上させ難かったりキャンバーを設け難くなったりする等、側構体の組立作業性が低下するという問題点があった。   However, in the above-mentioned conventional technology, it is difficult to adjust the finished dimension of the side structure in the vehicle length direction, so that it is difficult to improve the precision of the finished dimension or to provide a camber due to the influence of manufacturing errors such as curtains. There is a problem that the assembly workability of the side structure is lowered.

本発明は上述した問題点を解決するためになされたものであり、幕板等の製作誤差の影響を受け難くすることができ、組立作業性を向上できる鉄道車両の側構体を提供することを目的とする。   The present invention has been made to solve the above-described problems, and provides a side structure of a railway vehicle that can be hardly affected by manufacturing errors such as curtains and can improve assembly workability. Objective.

課題を解決するための手段および発明の効果Means for Solving the Problems and Effects of the Invention

この目的を達成するために請求項１記載の鉄道車両の側構体によれば、窓開口部および入口開口部を有し骨部材に側外板が接合され、入口開口部に入口枠が配置される。側外板は、窓開口部の上に幕板が位置し、窓開口部間に吹寄板が位置し、窓開口部の下に腰板が位置する。幕板は、複数に分割して配置され、その複数の幕板の側縁同士が入口開口部の上で突き合わせられる。入口枠は、左右の縦枠部材と、その左右の縦枠部材の下部および上部をそれぞれ連結する下部枠部材および上部枠部材とを有する。上部枠部材は、入口開口部の上側、且つ、互いに突き合わせられた複数の幕板の側縁の車幅方向外側に位置するので、上部枠部材によって幕板の側縁（継ぎ目）を視認し難くできる。よって、見栄えを良くできる。   In order to achieve this object, according to the side structure of the railway vehicle according to claim 1, the side skin is joined to the bone member having the window opening and the entrance opening, and the entrance frame is arranged in the entrance opening. The The side outer plate has a curtain plate positioned above the window opening, a blowing plate positioned between the window openings, and a waist plate positioned below the window opening. The curtain is divided into a plurality of parts, and the side edges of the curtains are abutted on the entrance opening. The entrance frame includes left and right vertical frame members, and a lower frame member and an upper frame member that connect lower and upper portions of the left and right vertical frame members, respectively. Since the upper frame member is located on the upper side of the entrance opening and on the outer side in the vehicle width direction of the side edges of the plurality of curtain plates butted against each other, it is difficult for the upper frame member to visually recognize the side edges (joints) of the curtain plate. it can. Therefore, the appearance can be improved.

また、互いに突き合わせられた複数の幕板の側縁の少なくとも一部が互いに非接合とされ、少なくとも幕板に入口枠が接合されるので、入口枠と幕板とを接合する位置や角度を調整することにより、側構体の上部側の車長方向の完成寸法の調整を容易にできる。また、幕板の溶接量を減らすことができるので、幕板の溶接による歪みを最小限にすることができる。その結果、容易に、側構体の上部側の車長方向の完成寸法を、側構体の下部側の車長方向の完成寸法より僅かに長くすることができる。そのため、幕板等の部材の製作誤差の影響を受け難くすることができ、キャンバーを容易に設けることができる。よって、側構体の組立作業性を向上できる効果がある。   Also, at least a part of the side edges of the plurality of curtains butted against each other is not joined to each other, and at least the entrance frame is joined to the curtain, so the position and angle at which the entrance frame and the curtain are joined are adjusted. By doing so, it is possible to easily adjust the completed dimension in the vehicle length direction on the upper side of the side structure. Further, since the amount of welding of the curtain plate can be reduced, distortion due to the welding of the curtain plate can be minimized. As a result, it is possible to easily make the completed dimension in the vehicle length direction on the upper side of the side structure slightly longer than the completed dimension in the vehicle length direction on the lower side of the side structure. Therefore, it is possible to make it difficult to be affected by manufacturing errors of members such as curtains, and the camber can be easily provided. Therefore, there is an effect that the assembly workability of the side structure can be improved.

請求項２記載の鉄道車両の側構体によれば、幕板は、側縁の一部が溶接により接合されると共に側縁の残部が非接合とされるので、側縁の一部が接合された状態で（幕板の車長方向長さがほぼ決められた状態で）、幕板を僅かに曲げることができる。これにより幕板にアーチ状の上反りを設けることができるので、請求項１の効果に加え、側構体にキャンバーを設け易くできる効果がある。   According to the side structure of the railway vehicle according to claim 2, since the curtain has a part of the side edge joined by welding and the remaining part of the side edge is not joined, the part of the side edge is joined. The curtain plate can be bent slightly in a state where the curtain plate has been substantially determined in the vehicle length direction. As a result, the curtain plate can be provided with an arch-shaped upward warp, so that in addition to the effect of the first aspect, the camber can be easily provided on the side structure.

請求項３記載の鉄道車両の側構体によれば、幕板は、側縁の上端部が溶接により接合されると共に側縁の下端側が非接合とされるので、側縁の上端側が接合された状態で（幕板の車長方向長さがほぼ決められた状態で）、幕板を僅かに曲げることができる。これにより、幕板にアーチ状の上反りを設けることができる。さらに、入口枠は側縁の下端側の車幅方向外側に上部枠部材が配置されるので、側縁の下端側を覆い隠すことができる。その結果、上部枠部材によって幕板の側縁の下端側（非接合の部分）を視認し難くできる。よって、請求項１又は２の効果に加え、キャンバーを設け易くしつつ側構体の見栄えを良くできる効果がある。   According to the side structure of the railway vehicle according to claim 3, since the upper end of the side edge is joined by welding and the lower end side of the side edge is not joined, the upper end side of the side edge is joined. In this state (with the length of the curtain plate in the vehicle length direction being almost determined), the curtain plate can be bent slightly. As a result, the curtain plate can be provided with an arched warp. Furthermore, since the upper frame member is disposed on the outer side in the vehicle width direction on the lower end side of the side edge, the entrance frame can cover the lower end side of the side edge. As a result, it is difficult to visually recognize the lower end side (non-joined portion) of the side edge of the curtain plate by the upper frame member. Therefore, in addition to the effect of Claim 1 or 2, there exists an effect which can improve the appearance of a side structure, making it easy to provide a camber.

請求項４記載の鉄道車両の側構体によれば、幕板は、側縁の内、溶接により接合された一部または上端部の車高方向長さが、非接合とされる非接合部の車高方向長さより小さい値に設定されているので、幕板の側縁が接合された状態で幕板を曲げ変形させ易くできる。その結果、請求項２又は３の効果に加え、幕板にアーチ状の上反りを設け易くすることができる効果がある。   According to the side structure of the railway vehicle according to claim 4, the curtain plate is a non-joined portion in which the vehicle height direction length of a part or the upper end portion joined by welding is not joined. Since it is set to a value smaller than the length in the vehicle height direction, the curtain can be easily bent and deformed in a state where the side edges of the curtain are joined. As a result, in addition to the effect of the second or third aspect, there is an effect that it is possible to easily provide an arch-shaped upper warp in the curtain plate.

請求項５記載の鉄道車両の側構体によれば、幕板は、側縁の内の非接合とされる非接合部が、車長方向に互いに間隔をあけて配置されるので、突き合わされた一方の幕板の側縁の非接合部が、他方の幕板の側縁に重なり合うことを防止できる。これにより、突き合わされた幕板同士が干渉すること防止できる。よって、請求項１から４のいずれかの効果に加え、車両の走行時に幕板同士が衝突して異音が生じたり幕板同士が擦れ合って摩耗粉が生じたりすることを防止できる効果がある。   According to the side structure of the railway vehicle according to claim 5, the curtain plate is abutted because the non-joined portions which are not joined in the side edges are arranged at intervals in the vehicle length direction. It is possible to prevent the non-joined portion of the side edge of one curtain plate from overlapping the side edge of the other curtain plate. As a result, it is possible to prevent the face plates that are abutted from interfering with each other. Therefore, in addition to the effect of any one of claims 1 to 4, it is possible to prevent the curtains from colliding with each other when the vehicle is running to generate an abnormal noise or rubbing between the curtains to generate wear powder. is there.

以下、本発明の好ましい実施の形態について、添付図面を参照して説明する。まず図１を参照して、本発明の鉄道車両の側構体１について説明する。図１は本発明の一実施の形態における鉄道車両の側構体１の側面図である。図１に示すように、鉄道車両の側構体１は縦骨部材３０及び横骨部材４０（後述する骨部材）に貼り付けられた側外板１０（後述する）を備えて構成される。骨部材および側外板１０により複数の窓開口部１ａ及び入口開口部１ｂが形成され、入口開口部１ｂに入口枠２０が配置される。本実施の形態では、入口開口部１ｂは側構体１の前後２箇所に形成される。   DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the accompanying drawings. First, a side structure 1 of a railway vehicle according to the present invention will be described with reference to FIG. FIG. 1 is a side view of a side structure 1 of a railway vehicle according to an embodiment of the present invention. As shown in FIG. 1, the side structure 1 of a railway vehicle includes a side outer plate 10 (described later) attached to a longitudinal bone member 30 and a transverse bone member 40 (a bone member described later). A plurality of window openings 1a and inlet openings 1b are formed by the bone member and the side outer plate 10, and the inlet frame 20 is disposed in the inlet openings 1b. In the present embodiment, the inlet openings 1 b are formed at two locations on the front and rear sides of the side structure 1.

図２を参照して側構体１及び入口枠２０について説明する。図２は側構体１及び入口枠２０の側面図である。なお、図２では、車長方向（図２左右方向）に延びる側構体１の一部の図示を省略すると共に、Ａで示す部分を部分的に拡大して図示している（但し、Ａで示す部分は、車両の車高方向（図２上下方向）の中間部分の図示を省略している）。側外板１０は、骨部材に貼り付けられて側構体１を構成する部材であり、窓開口部１ａの上に位置する幕板１１，１２と、窓開口部１ａ間に位置する吹寄板１３，１４，１５と、窓開口部１ａの下に位置する腰板１６，１７とを備えて構成される。   The side structure 1 and the entrance frame 20 will be described with reference to FIG. FIG. 2 is a side view of the side structure 1 and the entrance frame 20. In FIG. 2, a part of the side structure 1 extending in the vehicle length direction (left and right direction in FIG. 2) is not shown, and a portion indicated by A is partially enlarged (note that A The portion shown in the figure is an illustration of an intermediate portion in the vehicle height direction (vertical direction in FIG. 2). The side outer plate 10 is a member that is affixed to a bone member and constitutes the side structure 1, and the curtain plates 11 and 12 positioned on the window opening 1 a and the blowing plate positioned between the window openings 1 a. 13, 14, 15 and waist plates 16, 17 located below the window opening 1 a.

本実施の形態では、側構体１は、複数の構体ブロックＢ１，Ｂ２及び入口枠２０を接合して構成されている。構体ブロックＢ１は、車体前後に配置されるブロックであり、骨部材（図示せず）に側外板１０としての幕板１１、吹寄板１３及び腰板１６が貼り付けられ、作成される。構体ブロックＢ２は、車体中央に配置されるブロックであり、骨部材（図示せず）に側外板１０としての幕板１２、吹寄板１４及び腰板１７が貼り付けられ、作成される。構体ブロックＢ１，Ｂ２の間に入口枠２０が挟まれるように配置され、それぞれ溶接によって接合される。構体ブロックＢ１，Ｂ２及び入口枠２０を接合して構成される側構体１は、各構体ブロックＢ１，Ｂ２に貼り付ける側外板１０の車長方向の寸法を小さくできる。よって、車両全長に亘って連続する側外板と比較して、側外板１０の取扱を容易にできる。   In the present embodiment, the side structure 1 is configured by joining a plurality of structure blocks B1 and B2 and the entrance frame 20. The structure block B1 is a block disposed in the front and rear of the vehicle body, and is created by attaching a curtain plate 11, a blowing plate 13 and a waist plate 16 as a side outer plate 10 to a bone member (not shown). The structure block B2 is a block disposed at the center of the vehicle body, and is created by attaching a curtain plate 12, a blowing plate 14 and a waist plate 17 as the side outer plate 10 to a bone member (not shown). It arrange | positions so that the entrance frame 20 may be pinched | interposed between structure block B1, B2, and each is joined by welding. The side structure 1 configured by joining the structure blocks B1 and B2 and the entrance frame 20 can reduce the dimension in the vehicle length direction of the side outer plate 10 to be attached to each structure block B1 and B2. Therefore, handling of the side outer plate 10 can be facilitated as compared with the side outer plate that is continuous over the entire length of the vehicle.

なお、幕板１１，１２、腰板１６，１７は、車長方向に沿って突条状に形成されると共に車幅方向外側（図２紙面手前側）に突出する凸部１１ａ，１２ａ，１６ａ，１７ａが、幕板１１，１２、腰板１６，１７を部分的に屈曲させることにより形成される。凸部１１ａ，１２ａ，１６ａ，１７ａを設けることにより、幕板１１，１２、腰板１６，１７の剛性を向上できる。その結果、溶接による熱変形も抑制できる。   The curtain plates 11 and 12 and the waist plates 16 and 17 are convex portions 11a, 12a, 16a, which are formed in a ridge shape along the vehicle length direction and project outward in the vehicle width direction (front side in FIG. 2). 17a is formed by partially bending the curtain plates 11 and 12 and the waist plates 16 and 17. By providing the convex portions 11a, 12a, 16a and 17a, the rigidity of the curtain plates 11 and 12 and the waist plates 16 and 17 can be improved. As a result, thermal deformation due to welding can be suppressed.

幕板１１は妻構体（図示せず）と入口開口部１ｂとの間に配置され、幕板１２は入口開口部１ｂ間に配置される。幕板１１，１２により妻構体間（約２５ｍの側構体１の全長）は複数に分割される。本実施の形態では、入口開口部１ｂは側構体１に２つ設けられているので、側構体１に３枚の幕板が配置される。幕板１１，１２は、側縁１１ｂ，１２ｂ同士が入口開口部１ｂの上で突き合わせられている。   The curtain plate 11 is disposed between a wife structure (not shown) and the entrance opening 1b, and the curtain plate 12 is disposed between the entrance opening 1b. The curtains 11 and 12 divide the wife structure (the total length of the side structure 1 of about 25 m) into a plurality of pieces. In the present embodiment, two entrance openings 1 b are provided in the side structure 1, so that three curtains are arranged in the side structure 1. In the curtain plates 11 and 12, the side edges 11b and 12b are abutted on the entrance opening 1b.

部分拡大図Ａに示すように、幕板１１，１２は同一面内に位置し、側縁１１ｂ，１２ｂが車長方向に互いに間隔をあけて配置される（その間隔は、本実施の形態では約２ｍｍ）。側縁１１ｂ，１２ｂの一部に突合せ溶接により接合部１８がスポット状に形成されることで、幕板１１，１２は接合されている。その側縁１１ｂ，１２ｂの残部に、非接合とされる非接合部１９が形成される。本実施の形態では、側縁１１ｂ，１２ｂの上端部に接合部１８が形成され、側縁１１ｂ，１２ｂの下端側に非接合部１９が形成される。また、接合部１８の車高方向（図２上下方向）長さ（本実施の形態では約５０ｍｍ）は、非接合部１９の車高方向長さ（本実施の形態では約３００ｍｍ）より小さい値に設定されている。幕板１１，１２の溶接長さを小さくすることで、溶接により生じる幕板１１，１２の歪みを抑制できる。   As shown in the partially enlarged view A, the curtain plates 11 and 12 are located in the same plane, and the side edges 11b and 12b are arranged at intervals in the vehicle length direction. About 2 mm). The curtain plates 11 and 12 are joined by forming the joint 18 in a spot shape on a part of the side edges 11b and 12b by butt welding. Non-joining portions 19 that are not joined are formed in the remaining portions of the side edges 11b and 12b. In the present embodiment, the joining portion 18 is formed at the upper end portions of the side edges 11b and 12b, and the non-joining portion 19 is formed at the lower end side of the side edges 11b and 12b. Further, the vehicle height direction (vertical direction in FIG. 2) length of the joint portion 18 (about 50 mm in the present embodiment) is smaller than the vehicle height direction length of the non-joint portion 19 (about 300 mm in the present embodiment). Is set to By reducing the welding length of the curtain plates 11 and 12, distortion of the curtain plates 11 and 12 caused by welding can be suppressed.

入口枠２０は、入口開口部１ｂより外縁が大きく形成される矩形枠状の部材である。入口枠２０は、所定の間隔をあけて左右に位置する縦枠部材２１，２２と、縦枠部材２１，２２の下部を連結する下部枠部材２３と、縦枠部材２１，２２の上部を連結する上部枠部材２４とを備え、入口開口部１ｂ周りの側外板１０に接合される。入口枠２０は、車高方向長さが、側構体１の車高方向長さと略同一の値に設定されており、入口枠２０の左右方向長さは入口開口部１ｂの左右方向長さより少し大きめに設定されている。   The entrance frame 20 is a rectangular frame-shaped member having a larger outer edge than the entrance opening 1b. The entrance frame 20 connects the vertical frame members 21 and 22 positioned on the left and right sides with a predetermined interval, the lower frame member 23 connecting the lower portions of the vertical frame members 21 and 22, and the upper portions of the vertical frame members 21 and 22. And an upper frame member 24 that is joined to the side outer plate 10 around the inlet opening 1b. The length of the entrance frame 20 in the vehicle height direction is set to be approximately the same as the length of the side structure 1 in the vehicle height direction, and the lateral length of the entrance frame 20 is slightly smaller than the lateral length of the entrance opening 1b. It is set large.

上部枠部材２４は、入口開口部１ｂの上側かつ幕板１１，１２の側縁１１ｂ，１２ｂの車幅方向外側（図２紙面手前側）に配置される部材であり、車高方向長さが、幕板１１，１２の側縁１１ｂ，１２ｂの車高方向長さより少し小さめに設定されている。   The upper frame member 24 is a member disposed on the upper side of the entrance opening 1b and on the outer side in the vehicle width direction (front side in FIG. 2) of the side edges 11b and 12b of the curtain plates 11 and 12, and has a vehicle height direction length. The side edges 11b and 12b of the curtain plates 11 and 12 are set slightly smaller than the vehicle height direction length.

なお、側外板１０（幕板１１，１２及び腰板１６，１７）は、入口枠２０と重なり合う部分に、凸部１１ａ，１２ａ，１６ａ，１７ａが突設されていない平坦な領域が設けられている。その側外板１０の平坦な領域に入口枠２０が接合される。側外板１０と入口枠２０との隙間を小さくできるので、側外板１０と入口枠２０とを接合するときの溶接による歪みやシールの工数を減らすことができる。   The side outer plate 10 (the curtain plates 11 and 12 and the waist plates 16 and 17) is provided with a flat region where the convex portions 11a, 12a, 16a and 17a are not projected at a portion overlapping the entrance frame 20. Yes. The inlet frame 20 is joined to the flat region of the side outer plate 10. Since the gap between the side outer plate 10 and the inlet frame 20 can be reduced, the distortion caused by welding and the number of sealing steps when the side outer plate 10 and the inlet frame 20 are joined can be reduced.

次に図３（ａ）及び図３（ｂ）を参照して側外板１０（吹寄板１４及び腰板１７）の接合構造について説明する。図３（ａ）は図２のＩＩＩａで示す部分を拡大して示した側外板１０の側面図であり、図３（ｂ）は図３（ａ）のＩＩＩｂ−ＩＩＩｂ線における側外板１０の断面図である。なお、図３（ａ）及び図３（ｂ）は吹寄板１４と腰板１７との接合箇所を図示しているが、他の吹寄板と腰板との間、幕板と吹寄板との間も、吹寄板１４と腰板１７との間と同様に接合されるので、それらの図示は省略する。   Next, the joining structure of the side outer plates 10 (the blowing plate 14 and the waist plate 17) will be described with reference to FIGS. 3 (a) and 3 (b). 3A is a side view of the side outer plate 10 shown by enlarging a portion indicated by IIIa in FIG. 2, and FIG. 3B is a side outer plate 10 taken along the line IIIb-IIIb in FIG. 3A. FIG. 3 (a) and 3 (b) illustrate the joint location between the blowing plate 14 and the waist plate 17, but between the other blowing plates and the waist plate, the curtain plate and the blowing plate, Since the joints are joined in the same manner as between the blowing plate 14 and the waist plate 17, their illustration is omitted.

図３（ａ）及び図３（ｂ）に示すように、吹寄板１４及び腰板１７は同一面内に位置し、吹寄部１４の下縁から下方に向けて張り出す張出部１４ａが、腰板１７に面して腰板１７の車幅方向外側（図３（ａ）紙面手前側、図３（ｂ）右側）に位置する。腰板１７と張出部１４ａとの間は、抵抗スポット溶接、レーザ溶接等の手段で溶接され接合される。   As shown in FIGS. 3A and 3B, the blowing plate 14 and the waist plate 17 are located in the same plane, and an overhanging portion 14a projecting downward from the lower edge of the blowing portion 14 is provided. It faces the waist plate 17 and is located on the outer side in the vehicle width direction of the waist plate 17 (FIG. 3 (a) on the front side of the drawing, right side of FIG. 3 (b)). The waist plate 17 and the overhanging portion 14a are welded and joined by means such as resistance spot welding or laser welding.

なお、吹寄部１４は、入口開口部１ｂの周囲であって入口枠２０（図２参照）と重なり合う部分の張出部１４ａが省略されている。同一面内に位置する吹寄板１４及び腰板１７と入口枠２０との隙間を小さくできるので、吹寄板１４及び腰板１７と入口枠２０とを接合するときの溶接による歪みやシールの工数を減らすことができる。   Note that the blowing portion 14 is omitted from the overhanging portion 14a that overlaps the inlet frame 20 (see FIG. 2) around the inlet opening 1b. Since the gap between the blowing plate 14 and the waist plate 17 located in the same plane and the entrance frame 20 can be reduced, the distortion caused by welding when joining the blowing plate 14 and the waist plate 17 and the entrance frame 20 and the man-hour of sealing are reduced. Can be reduced.

次に図３（ｃ）、図４（ａ）及び図４（ｂ）を参照して、側構体１の構造について説明する。図３（ｃ）は車体内側から視た側構体１の部分側面図であり、図４（ａ）は図３（ｃ）のＩＶａ−ＩＶａ線における側構体１の断面図であり、図４（ｂ）は図４（ａ）の矢印ＩＶｂ方向視における側構体の側面図である。なお、図３（ｃ）では主に幕板１１，１２部分を図示し、図４（ａ）及び図４（ｂ）では屋根構体５も併せて図示する。   Next, the structure of the side structure 1 will be described with reference to FIGS. 3 (c), 4 (a), and 4 (b). 3C is a partial side view of the side structure 1 viewed from the inside of the vehicle body, and FIG. 4A is a cross-sectional view of the side structure 1 taken along the line IVa-IVa in FIG. 3C. FIG. 4B is a side view of the side structure as viewed in the direction of arrow IVb in FIG. 3C mainly shows the curtain plates 11 and 12, and FIGS. 4A and 4B also show the roof structure 5. FIG.

図３（ｃ）に示すように幕板１１，１２は、車体内側にそれぞれ裏板３４，３５が配設されている。裏板３４，３５は、幕板１１，１２と一体に重ね接合され幕板１１，１２を補強し、側外板１０の一部を構成する。側外板１０は、車高方向（図３（ｃ）上下方向）に配設される縦骨部材３０と、車長方向（図３（ｃ）左右方向）に配設される横骨部材４０とに接合される。縦骨部材３０は、一対のフランジ３０ａを有する断面ハット形状に形成され、フランジ３０ａがスポット溶接により裏板３４，３５に重ね接合される。横骨部材４０も同様に、一対のフランジ（図示せず）を有する断面ハット形状に形成され、フランジがスポット溶接により裏板３４，３５（側外板１０）に重ね接合される。   As shown in FIG. 3C, the curtain plates 11 and 12 are provided with back plates 34 and 35, respectively, inside the vehicle body. The back plates 34 and 35 are integrally overlapped with the curtain plates 11 and 12 to reinforce the curtain plates 11 and 12 and constitute a part of the side outer plate 10. The side skin 10 includes a longitudinal bone member 30 disposed in the vehicle height direction (FIG. 3 (c) vertical direction) and a lateral bone member 40 disposed in the vehicle length direction (FIG. 3 (c) left-right direction). To be joined. The longitudinal bone member 30 is formed in a cross-sectional hat shape having a pair of flanges 30a, and the flange 30a is overlapped and joined to the back plates 34 and 35 by spot welding. Similarly, the transverse bone member 40 is formed in a cross-sectional hat shape having a pair of flanges (not shown), and the flanges are joined to the back plates 34 and 35 (side outer plate 10) by spot welding.

図４（ａ）に示すように、縦骨部材３０の上端部には連結具３１が接合されている。接合具３１は断面略コ字状に形成される部材であり、両側面が縦骨部材３０に重ね接合される。連結部３１の両側面および底面に上部接合具３２が連結される。上部接合具３２は、縦骨部材３０と屋根構体５とを連結し接合するための金具である。上部接合具３２の上端部が屋根構体５に接合されることにより、縦骨部材３０と屋根構体５とが連結される。縦骨部材３０の下端部には、断面略コ字状に形成された下部接合具３３が連結される。下部接合部３３は裏板３４，３５の下端側を固定するための部材である。   As shown in FIG. 4A, a connecting tool 31 is joined to the upper end portion of the longitudinal bone member 30. The connector 31 is a member formed in a substantially U-shaped cross section, and both side surfaces are overlapped and bonded to the longitudinal bone member 30. The upper connector 32 is connected to both side surfaces and the bottom surface of the connecting portion 31. The upper joint 32 is a metal fitting for connecting and joining the longitudinal bone member 30 and the roof structure 5. By joining the upper end part of the upper joint tool 32 to the roof structure 5, the vertical bone member 30 and the roof structure 5 are connected. A lower joint 33 having a substantially U-shaped cross section is connected to the lower end of the longitudinal bone member 30. The lower joint portion 33 is a member for fixing the lower ends of the back plates 34 and 35.

裏板３４は、車体内側（図４（ａ）左側）に向かって屈曲される上縁屈曲部３４ａが、車長方向（図４（ａ）紙面垂直方向）に沿って上縁に形成される。また、車体内側に向かって屈曲される下縁屈曲部３４ｂが、車長方向に沿って裏板３４の下縁に形成される。下縁屈曲部３４ｂには、車高方向上方に向かって屈曲形成される屈曲部３４ｃが連成され、屈曲部３４ｃは下部接合具３３に接合される。   The back plate 34 is formed with an upper edge bent portion 34a bent toward the inner side of the vehicle body (left side in FIG. 4A) at the upper edge along the vehicle length direction (FIG. 4A). . Further, a lower edge bent portion 34b bent toward the inner side of the vehicle body is formed at the lower edge of the back plate 34 along the vehicle length direction. The lower edge bent portion 34 b is coupled with a bent portion 34 c that is bent upward in the vehicle height direction, and the bent portion 34 c is joined to the lower connector 33.

図３（ｃ）に示すように、裏板３５は、裏板３４と同様に屈曲部３５ｃが形成されている。屈曲部３５ｃは、接合金具３６により横骨部材４０と連結される。以上のように裏板３４（裏板３５）は上縁屈曲部３４ａ及び下縁屈曲部３４ｂを備えているので、裏板３４（裏板３５）の上下端の剛性を向上させることができる。   As shown in FIG. 3C, the back plate 35 is formed with a bent portion 35 c similarly to the back plate 34. The bent portion 35 c is connected to the transverse bone member 40 by the joint fitting 36. As described above, since the back plate 34 (back plate 35) includes the upper edge bent portion 34a and the lower edge bent portion 34b, the rigidity of the upper and lower ends of the back plate 34 (back plate 35) can be improved.

屈曲部３４ｃ（屈曲部３５ｃ）が下縁屈曲部３４ｂに連成されると共に下部接合具３３を介して縦骨部材３０に接合されることで、屈曲部３４ｃ（屈曲部３５ｃ）により裏板３４（裏板３５）の下縁側（入口開口部１ｂの上方）の剛性を大きくできる。また、裏板３４，３５は幕板１１，１２とそれぞれ重ね接合されているので、接合金具３６によって横骨部材４０と連結されることにより、幕板１１，１２の剛性を大きくできる。   The bent portion 34c (bent portion 35c) is coupled to the lower edge bent portion 34b and joined to the longitudinal bone member 30 via the lower joint 33, whereby the back plate 34 is formed by the bent portion 34c (bent portion 35c). The rigidity of the lower edge side (above the entrance opening 1b) of the (back plate 35) can be increased. Further, since the back plates 34 and 35 are overlapped and joined to the curtain plates 11 and 12, respectively, the rigidity of the curtain plates 11 and 12 can be increased by being connected to the horizontal bone member 40 by the joining bracket 36.

ここで、幕板１１，１２は、側縁１１ｂ，１２ｂ（図２参照）の下部側が互いに非接合とされる非接合部１９が形成されているので、側縁１１ｂ，１２ｂの下部側は互いに分離される。しかし、接合金具３６を介して裏板３４，３５が横骨部材４０と連結されることで、幕板１１，１２の剛性を大きくできる。よって、幕板１１，１２の側縁１１ｂ，１２ｂが上下に亘って接合されていなくても、車両の走行中の幕板１１，１２の振動等を防止できる。また、幕板１１，１２の下縁（入口開口部１ｂの上方）の横骨部材を省略できるので、その分だけ側構体１を軽量化できる。   Here, since the curtain plates 11 and 12 are formed with non-joining portions 19 in which the lower sides of the side edges 11b and 12b (see FIG. 2) are not joined to each other, the lower sides of the side edges 11b and 12b are mutually attached. To be separated. However, the rigidity of the curtain plates 11 and 12 can be increased by connecting the back plates 34 and 35 to the transverse bone member 40 via the joint fitting 36. Therefore, even if the side edges 11b and 12b of the curtain plates 11 and 12 are not joined vertically, vibration of the curtain plates 11 and 12 while the vehicle is traveling can be prevented. Further, since the horizontal bone member at the lower edge of the curtain plates 11 and 12 (above the entrance opening 1b) can be omitted, the side structure 1 can be reduced in weight accordingly.

図４（ａ）に戻って説明する。幕板１１は、車体内側（図４（ａ）左側）に向かって屈曲される上縁屈曲部１１ｃが、車長方向（図４（ａ）紙面垂直方向）に沿って上縁に形成される。上縁屈曲部１１ｃは、裏板３４の上縁に形成される上縁屈曲部３４ａより上方に位置する。上縁屈曲部１１ｃが形成されているので、幕板１１の上端部の剛性を向上できる。   Returning to FIG. The curtain 11 has an upper edge bent portion 11c bent toward the inner side of the vehicle body (the left side in FIG. 4A) at the upper edge along the vehicle length direction (the vertical direction in FIG. 4A). . The upper edge bent portion 11 c is located above the upper edge bent portion 34 a formed on the upper edge of the back plate 34. Since the upper edge bent portion 11c is formed, the rigidity of the upper end portion of the curtain plate 11 can be improved.

図４（ａ）及び図４（ｂ）に示すように屋根構体５は、屋根外板と一体に形成される雨樋５ａと、その雨樋５ａの底部に接合されると共に車高方向下向きに延設される延設部５ｂとを備えている。雨樋５ａ及び延設部５ｂは車長方向（図４（ａ）紙面垂直方向、図４（ｂ）左右方向）に沿って設けられている。延設部５ｂは、幕板１１の上端部の車幅方向外側（図４（ａ）右側、図４（ｂ）紙面手前側）に位置する。   As shown in FIGS. 4 (a) and 4 (b), the roof structure 5 is joined to the rain gutter 5a formed integrally with the roof outer plate and the bottom of the gutter 5a, and is directed downward in the vehicle height direction. And an extended portion 5b that is extended. The rain gutter 5a and the extending portion 5b are provided along the vehicle length direction (FIG. 4A, the direction perpendicular to the paper surface, FIG. 4B, the left-right direction). The extending portion 5b is located on the outer side in the vehicle width direction (the right side in FIG. 4A, the front side in FIG. 4B) of the upper end portion of the curtain plate 11.

上部枠部材２４（入口枠２０）は、車幅方向内側（図４（ａ）左側、図４（ｂ）紙面奥側）に向かって延びる延長部２４ａが下縁に形成されている。延長部２４ａは、裏板３４の下縁に形成された下縁屈曲部３４ｂに当接して上部枠部材２４の車高方向（図４（ａ）及び図４（ｂ）上下方向）の位置決めをするための部位である。上部枠部材２４は、延長部２４ａが下縁屈曲部３４ｂに当接されるように装着されることで、幕板１１の車幅方向外側に位置すると共に、上部枠部材２４と延設部５ｂとの間に隙間（本実施の形態では約１０ｍｍ）が形成されるように寸法が設定されている。上部枠部材２４と幕板１１とはスポット溶接等により重ね接合される。   The upper frame member 24 (entrance frame 20) is formed with an extension 24a at the lower edge extending toward the inner side in the vehicle width direction (left side in FIG. 4A, rear side in FIG. 4B). The extension portion 24a contacts the lower edge bent portion 34b formed on the lower edge of the back plate 34 to position the upper frame member 24 in the vehicle height direction (FIG. 4 (a) and FIG. 4 (b) vertical direction). It is a part to do. The upper frame member 24 is mounted so that the extended portion 24a is in contact with the lower edge bent portion 34b, so that the upper frame member 24 is positioned on the outer side in the vehicle width direction of the curtain plate 11, and the upper frame member 24 and the extended portion 5b. The dimension is set so that a gap (about 10 mm in this embodiment) is formed between the two. The upper frame member 24 and the curtain plate 11 are lap-joined by spot welding or the like.

以上のように、側構体１の車長を複数に分割した長さの幕板１１，１２を突き合わせることで側構体１を組み立てるので、側構体１の車長の長さ（本実施の形態では約２５ｍ）の幕板を製造する能力がなくても側構体１を組み立てることができる。また、幕板１１，１２は車長を分割した長さに設定されるので、全長の長い車両を製造する場合であっても、幕板１１，１２を陸送するときの特別な許可を不要とすることができる。その複数の幕板１１，１２を入口開口部１ｂの上側で突き合わせると共に、突き合わせた幕板１１，１２の側縁１１ｂ，１２ｂの車幅方向外側に上部枠部材２４（入口枠２０）を配置するので、上部枠部材２４によって幕板１１，１２の側縁１１ｂ，１２ｂ（継ぎ目）を視認し難くできる。よって、側構体１の見栄えを良くできる。   As described above, since the side structure 1 is assembled by abutting the curtain plates 11 and 12 having a length obtained by dividing the vehicle length of the side structure 1 into a plurality, the length of the vehicle length of the side structure 1 (this embodiment) Then, the side structure 1 can be assembled without the ability to manufacture a curtain of about 25 m). Further, since the curtain plates 11 and 12 are set to a length obtained by dividing the vehicle length, a special permission for transporting the curtain plates 11 and 12 to land is not required even when a vehicle having a long overall length is manufactured. can do. The plurality of curtain plates 11 and 12 are abutted on the upper side of the entrance opening 1b, and the upper frame member 24 (entrance frame 20) is disposed outside the side edges 11b and 12b of the abutted curtain plates 11 and 12 in the vehicle width direction. Therefore, the side frames 11b and 12b (joints) of the curtain plates 11 and 12 can be made difficult to visually recognize by the upper frame member 24. Therefore, the appearance of the side structure 1 can be improved.

また、上部枠部材２４と延設部５ｂとの間に隙間が形成されるように上部枠部材２４の寸法が設定されているので、幕板１１や入口枠２０等の製作誤差（特に車高方向の製作誤差）を吸収できる。なお、幕板１１，１２の側縁１１ｂ，１２ｂは上端部に接合部１８（図２参照）が形成されている。上部枠部材２４と延設部５ｂとの間に形成される隙間は、接合部１８の車幅方向外側に位置するので、その隙間を、側構体１の外側から視認されないようにできる。これにより側構体１の見栄えをさらに良くすることができる。   In addition, since the size of the upper frame member 24 is set so that a gap is formed between the upper frame member 24 and the extending portion 5b, manufacturing errors (particularly the vehicle height) of the curtain plate 11, the entrance frame 20, and the like are set. (Manufacturing errors in direction) can be absorbed. The side edges 11b and 12b of the curtain plates 11 and 12 are formed with a joint 18 (see FIG. 2) at the upper end. Since the gap formed between the upper frame member 24 and the extended portion 5 b is located on the outer side in the vehicle width direction of the joint portion 18, the gap can be prevented from being visually recognized from the outside of the side structure 1. Thereby, the appearance of the side structure 1 can be further improved.

互いに突き合わせられた幕板１１，１２の側縁１１ｂ，１２ｂの少なくとも一部が互いに非接合とされ、幕板１１，１２（側外板１０）に入口枠２０が接合されるので、幕板１１，１２の溶接量を減らすことができる。その結果、幕板１１，１２の溶接による歪みを最小限にできる。従って、入口枠２０と幕板１１，１２とを接合する位置や角度を調整することにより、側構体１の上部側の車長方向の完成寸法の調整を容易にできる。溶接による歪みを最小限にできるので、側縁１１ｂ，１２ｂ間の隙間の大きさや角度を適宜設定できるからである。その結果、容易に、側構体１の上部側の車長方向の完成寸法を、側構体１の下部側の車長方向の完成寸法より僅かに長くすることができる。そのため、幕板１１，１２等の部材の製作誤差の影響を受け難くすることができ、キャンバーを容易に設けることができる。よって、側構体１の組立作業性を向上できる。   Since at least a part of the side edges 11b, 12b of the curtain plates 11, 12 abutted against each other is not joined to each other, and the entrance frame 20 is joined to the curtain plates 11, 12 (side outer plate 10), the curtain plate 11 , 12 can be reduced. As a result, distortion due to welding of the curtain plates 11 and 12 can be minimized. Therefore, by adjusting the position and angle at which the entrance frame 20 and the curtain plates 11 and 12 are joined, it is possible to easily adjust the completed dimension in the vehicle length direction on the upper side of the side structure 1. This is because distortion due to welding can be minimized, and the size and angle of the gap between the side edges 11b and 12b can be set as appropriate. As a result, the completed dimension in the vehicle length direction on the upper side of the side structure 1 can be easily made slightly longer than the completed dimension in the vehicle length direction on the lower side of the side structure 1. Therefore, it is difficult to be affected by manufacturing errors of members such as the curtain plates 11 and 12, and the camber can be easily provided. Therefore, the assembly workability of the side structure 1 can be improved.

また、幕板１１，１２は、側縁１１ｂ，１２ｂの一部が溶接により接合されると共に側縁１１ｂ，１２ｂの残部が非接合とされる。そのため、側縁１１ｂ，１２ｂの一部を接合すると共に（接合部１８により幕板１１，１２を仮固定した状態で）、非接合部１９の間隔を調整することで、幕板１１，１２の角度を僅かに調整できる。これにより幕板１１，１２にアーチ状の上反りを設けることができる。よって、側構体１にキャンバーを設け易くできる。   Further, in the curtain plates 11 and 12, a part of the side edges 11b and 12b is joined by welding, and the remaining part of the side edges 11b and 12b is not joined. Therefore, by joining a part of the side edges 11b and 12b (with the curtain plates 11 and 12 temporarily fixed by the joint portion 18) and adjusting the distance between the non-joint portions 19, The angle can be adjusted slightly. As a result, the curtain plates 11 and 12 can be provided with an arch-shaped warp. Therefore, the camber can be easily provided on the side structure 1.

さらに、入口枠２０は側縁１１ｂ，１２ｂの下端側の車幅方向外側に上部枠部材２４が配置されるので、側縁１１ｂ，１２ｂの下端側を上部枠部材２４によって覆い隠すことができる。その結果、上部枠部材２４によって幕板１１，１２の側縁１１ｂ，１２ｂの下端側の非接合部１９を視認し難くできる。よって、側構体１の見栄えを良くできる。   Further, since the upper frame member 24 is arranged on the outer side in the vehicle width direction on the lower end side of the side edges 11b and 12b, the lower end side of the side edges 11b and 12b can be covered with the upper frame member 24. As a result, the upper frame member 24 makes it difficult to visually recognize the non-joining portion 19 on the lower end side of the side edges 11b, 12b of the curtain plates 11, 12. Therefore, the appearance of the side structure 1 can be improved.

幕板１１，１２は、側縁１１ｂ，１２ｂの内、溶接により接合された接合部１８の車高方向長さが、非接合とされる非接合部１９の車高方向長さより小さい値に設定されている。よって、幕板１１，１２の側縁１１ｂ，１２ｂが接合された状態で幕板１１，１２を曲げ変形させ易くできる。また、接合部１８の溶接長さを短くすることで幕板１１，１２の熱変形を抑制できる。その結果、幕板１１，１２の変形を抑制しつつ、アーチ状の上反りを設け易くすることができる。   In the curtain plates 11 and 12, the length in the vehicle height direction of the joint portion 18 joined by welding among the side edges 11 b and 12 b is set to a value smaller than the length in the vehicle height direction of the non-joint portion 19 to be non-joined. Has been. Therefore, the curtain plates 11 and 12 can be easily bent and deformed in a state where the side edges 11b and 12b of the curtain plates 11 and 12 are joined. Moreover, the thermal deformation of the curtain plates 11 and 12 can be suppressed by shortening the welding length of the joint portion 18. As a result, it is possible to easily provide an arched warp while suppressing deformation of the curtain plates 11 and 12.

幕板１１，１２は、側縁１１ｂ，１２ｂの内の非接合とされる非接合部１９が、車長方向に互いに間隔をあけて配置されるので、車両の走行中に非接合部１９同士が干渉することを防止できる。よって、車両の走行時に異音が生じたり非接合部１９同士が擦れ合って摩耗粉が生じたりすることを防止できる。   Since the non-joining portions 19 that are not joined among the side edges 11b and 12b are spaced apart from each other in the vehicle length direction, the curtain plates 11 and 12 are not joined to each other while the vehicle is running. Can be prevented from interfering. Therefore, it is possible to prevent abnormal noise from being generated during traveling of the vehicle or abrasion powder from being generated due to friction between the non-joining portions 19.

以上、実施の形態に基づき本発明を説明したが、本発明は上記実施の形態に何ら限定されるものではなく、本発明の趣旨を逸脱しない範囲内で種々の改良変形が可能であることは容易に推察できるものである。例えば、側構体１に形成される入口開口部１ｂの数や位置は一例であり、他の数値や位置を適宜選択して採用することは当然可能である。また、幕板１１，１２の側縁１１ｂ，１２ｂの車高方向長さや溶接部１８の車高方向長さ、非溶接部１９の間隔等の数値も一例であり、他の数値を適宜選択して採用することは当然可能である。   The present invention has been described above based on the embodiments. However, the present invention is not limited to the above embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention. It can be easily guessed. For example, the number and positions of the inlet openings 1b formed in the side structure 1 are merely examples, and other numerical values and positions can be appropriately selected and adopted as a matter of course. In addition, numerical values such as the vehicle height direction length of the side edges 11b and 12b of the curtain plates 11 and 12, the vehicle height direction length of the welded portion 18 and the interval of the non-welded portion 19 are also examples, and other numerical values may be selected as appropriate. Of course, it is possible to adopt.

上記実施の形態では、幕板１１，１２の側縁１１ｂ，１２ｂの上端部の一箇所に溶接部１８が形成される場合について説明したが、必ずしもこれに限られるものではなく、溶接部１８を側縁１１ｂ，１２ｂの複数箇所に形成することは当然可能である。また、上記実施の形態では、幕板１１，１２の側縁１１ｂ，１２ｂの上端部に溶接部１８が形成される場合について説明したが、必ずしもこれに限られるものではなく、溶接部１８を側縁１１ｂ，１２ｂの任意の箇所に形成することは当然可能である。   In the above embodiment, the case where the welded portion 18 is formed at one place on the upper ends of the side edges 11b and 12b of the curtain plates 11 and 12 is described. Of course, it is possible to form the side edges 11b and 12b at a plurality of locations. Moreover, although the said embodiment demonstrated the case where the welding part 18 was formed in the upper end part of the side edges 11b and 12b of the curtain plates 11 and 12, it is not necessarily restricted to this, The welding part 18 is made into the side. Of course, it is possible to form it in arbitrary locations of the edges 11b and 12b.

これらの場合も、入口枠２０と幕板１１，１２とを接合する位置や角度を調整することにより、側構体１の上部側（幕板１１，１２側）の車長方向の完成寸法の調整を容易にできる。その結果、本実施の形態と同様に、側構体１にキャンバーを容易に形成できる。   In these cases as well, by adjusting the position and angle at which the entrance frame 20 and the curtain plates 11 and 12 are joined, adjustment of the completed dimension in the vehicle length direction on the upper side of the side structure 1 (the curtain plates 11 and 12 side) is adjusted. Can be easily done. As a result, the camber can be easily formed on the side structure 1 as in the present embodiment.

上記実施の形態では、幕板１１，１２の側縁１１ｂ，１２ｂの上端部に溶接部１８が形成される場合について説明したが、必ずしもこれに限られるものではなく、側縁１１ｂ，１２ｂ間を溶接により接合しない（溶接部１８を設けない）構成とすることは当然可能である。側縁１１ｂ，１２ｂ間を溶接により接合しない場合も、入口枠２０と幕板１１，１２とを溶接によって接合することにより、幕板１１，１２を入口枠２０に接合できるからである。その結果、幕板１１，１２と入口枠２０とを接合する位置や角度を調整することにより、側構体１の上部側（幕板１１，１２側）の車長方向の完成寸法を調整できる。よって、溶接部１８を設けない場合も、本実施の形態と同様に、側構体１にキャンバーを容易に形成できる。   In the above embodiment, the case where the welded portion 18 is formed at the upper ends of the side edges 11b and 12b of the curtain plates 11 and 12 is described, but the present invention is not necessarily limited to this, and the space between the side edges 11b and 12b is not limited. Of course, it is possible to adopt a configuration in which welding is not performed (the welded portion 18 is not provided). This is because even when the side edges 11b and 12b are not joined by welding, the curtain plates 11 and 12 can be joined to the inlet frame 20 by joining the inlet frame 20 and the curtain plates 11 and 12 by welding. As a result, by adjusting the position and angle at which the curtain plates 11 and 12 and the entrance frame 20 are joined, the completed dimension in the vehicle length direction on the upper side of the side structure 1 (the curtain plates 11 and 12 side) can be adjusted. Therefore, even when the welded portion 18 is not provided, the camber can be easily formed on the side structure 1 as in the present embodiment.

上記実施の形態では、入口開口部１ｂの車長方向の中間位置で幕板１１，１２の側縁１１ｂ，１２ｂが突き合わせられる場合について説明したが、必ずしもこれに限られるものではなく、入口開口部１ｂの上で幕板１１，１２の側縁１１ｂ，１２ｂが突き合わせられていれば良い。入口開口部１ｂの上に幕板１１，１２の側縁１１ｂ，１２ｂが位置すれば、入口枠２０の上部枠部材２４によって側縁１１ｂ，１２ｂを覆うことができるからである。   In the above-described embodiment, the case where the side edges 11b and 12b of the curtain plates 11 and 12 are abutted at an intermediate position in the vehicle length direction of the inlet opening 1b has been described. It is only necessary that the side edges 11b and 12b of the curtain plates 11 and 12 are abutted on 1b. This is because if the side edges 11b and 12b of the curtain plates 11 and 12 are positioned on the entrance opening 1b, the side edges 11b and 12b can be covered by the upper frame member 24 of the entrance frame 20.
