According to these welding methods, since the amount of distortion generated in the metal base material to be welded is small, the first to third plate members 23 to 25 are hardly distorted. Therefore, the support column 19 can be formed with high dimensional accuracy and the moldability is improved. The same applies to the welding described below.

また、第４の板材２６は、第１の板材２３と第２の板材２４との間隔よりも幅広に形成されると共に、第１及び第２の板材２３，２４の長手方向の長さよりも短く形成されている。この第４の板材２６は、支柱１９において車両本体２の内側に向けて配置される。そして、第１及び第２の板材２３，２４の形状に沿うように第４の板材２６が配置され、第１、第２及び第４の板材２３，２４，２６が連続的に溶接される。また、第４の板材２６も、第１及び第２の板材２３，２４の湾曲部Ｃ及び直線部Ｄに沿って、第１及び第２の板材２３，２４に連続溶接により接合される。なお、第１及び第２の板材２３，２４の長手方向における第４の板材２６側の両端部は、接合部材２１及び接合部材２２を接合するために露出している。 Further, the fourth plate member 26 is formed wider than the distance between the first plate member 23 and the second plate member 24 and shorter than the length of the first and second plate members 23 and 24 in the longitudinal direction. Is formed. The fourth plate member 26 is disposed on the support column 19 toward the inside of the vehicle main body 2.

Are joined to the inner top portion 31 and the corrugated plate 18 on the lowermost side in the parallel direction.

[ 腰パネルの組立てについて ]
図５及び図７に示すように、先ず、一枚の外板１７の所定位置に支柱１９の第３の板材２５を当接配置し、支柱１９に外板１７を沿わせた状態で、外板１７の表面側（車両本体２の外側）から支柱１９の長手方向に沿って連続的に溶接する。符号Ｗ２は、支柱１９と外板１７とを溶接して形成された溶接ビードである。このとき、外板１７は、支柱１９の湾曲部Ｃ及び直線部Ｄに沿って裾絞り部Ｓ（図２参照）を形成するように変形させられて、支柱１９に連続的に溶接される。 [Assembly of waist panel]
As shown in FIGS. 5 and 7, first, the third plate member 25 of the support column 19 is placed in contact with a predetermined position of one outer plate 17, and the outer plate 17 is placed along the support column 19. Welding is continuously performed along the longitudinal direction of the column 19 from the surface side of the plate 17 (outside of the vehicle body 2). Reference sign W 2 is a weld bead formed by welding the support column 19 and the outer plate 17. At this time, the outer plate 17 is deformed so as to form a skirt throttle portion S (see FIG. 2) along the curved portion C and the straight portion D of the support column 19, and is continuously welded to the support column 19.

次いで、図５、図７及び図９に示すように、外板１７に沿うように波板１８Ａを配置させると同時に波板１８Ａの端部をフランジ部２８と外板１７との間に差し込む。そして、溶接装置３３を用いて、波板１８Ａの外側頂部３０と外板１７とを外側頂部３０の長手方向に沿って連続的に溶接する。符号Ｗ３は、外側頂部３０と外板１７とが溶接されて形成された溶接ビードである。さらに、波板１８Ａの内側頂部３１の長手方向における端部とフランジ部２８とを連続的に溶接する。符号Ｗ４は、内側頂部３１の端部とフランジ部２８とを溶接して形成された溶接ビードである。 Next, as shown in FIGS. 5, 7, and 9, the corrugated plate 18 A is disposed along the outer plate 17, and at the same time, the end portion of the corrugated plate 18 A is inserted between the flange portion 28 and the outer plate 17. Then, the outer apex 30 and the outer plate 17 of the corrugated sheet 18 A are continuously welded along the longitudinal direction of the outer apex 30 using the welding device 33. Reference sign W3 is a weld bead formed by welding the outer top 30 and the outer plate 17 together. Further, the end portion in the longitudinal direction of the inner top portion 31 of the corrugated plate 18A and the flange portion 28 are continuously welded. Reference sign W4 is a weld bead formed by welding the end portion of the inner top portion 31 and the flange portion 28.

同様に、外板１７に沿うように波板１８Ｂを配置させると同時に波板１８Ｂの端部をフランジ部２９と外板１７との間に差し込む。そして、波板１８Ｂの外側頂部３０と外板１７とを外側頂部３０の長手方向に沿って連続的に溶接する。さらに、波板１８Ｂの内側頂部３１の長手方向における端部とフランジ部２８とを連続的に溶接する。符号Ｗ６は、内側頂部３１の端部とフランジ部２８とを溶接して形成された溶接ビードである。 Similarly, the corrugated plate 18 B is disposed along the outer plate 17, and at the same time, the end portion of the corrugated plate 18 B is inserted between the flange portion 29 and the outer plate 17. Then, the outer top 30 and the outer plate 17 of the corrugated plate 18B are continuously welded along the longitudinal direction of the outer top 30. Furthermore, the edge part in the longitudinal direction of the inner side top part 31 of the corrugated sheet 18B and the flange part 28 are continuously welded. Reference sign W6 is a weld bead formed by welding the end portion of the inner top portion 31 and the flange portion 28.

このように一枚の外板１７を共有して四枚の波板１８を外板１７に溶接する際に、隣接した波板１８間に支柱１９を配置させて、波板１８同士を支柱１９に溶接して連結させていく。ここで、支柱１９は側構体ブロック１１において鉛直方向に設けられることになるため、腰パネル１６は、鉛直下向きの荷重に対して強い構造となる。また、外板１７に波板１８が溶接されることにより、腰パネル１６の剛性が強化され、外側頂部３０の長手方向に加わる荷重に対して強い構造となる。さらに、腰パネル１６には、支柱１９に形成された裾絞り部Ｓ（図２参照）が形成されることになる。このように、精度の良い支柱１９を外板１７に接合する際、外板１７は支柱１９の形状に合わせて変形するので、精度の良い支柱１９をもって精度の良い腰パネル１６を形成することができる。 In this way, when one outer plate 17 is shared and four corrugated plates 18 are welded to the outer plate 17, support columns 19 are arranged between adjacent corrugated plates 18, and the corrugated plates 18 are connected to each other. Weld and connect to. Here, since the support column 19 is provided in the vertical direction in the side structure block 11, the waist panel 16 has a structure strong against a vertically downward load. Further, by welding the corrugated plate 18 to the outer plate 17, the rigidity of the waist panel 16 is strengthened and a structure that is strong against a load applied in the longitudinal direction of the outer top portion 30 is obtained.
