To provide a water tank whose weight is reduced as much as possible without decreasing a conventional volume and whose durability while traveling at high speed is high in a water tank for a railway vehicle.SOLUTION: A water tank for a railway vehicle is composed of a rectangular cross sectional cylindrical barrel part 4 fixed under a floor board 2 of the railway vehicle and an end plate 5 closing at least one opening 8 of the cylindrical barrel part water-tightly. The end plate is composed of a rectangular plate shape body part and a bent plate part provided bent for an edge on each side of the body. An end surface of the opening of the cylindrical barrel part and an end surface of the bent plate part are bonded by butt-welding. A reinforcement member 7 fixed inside the cylindrical barrel part, and a wave removing plate 9 are fillet-welded on a front surface and a back surface of the bent plate part.SELECTED DRAWING: Figure 1
【課題】鉄道車両用の水タンクにおいて、従来の容積を減らすことなく極力軽量化を行うと共に、高速走行時において耐久性の高い水タンクを提供する。【解決手段】鉄道車両用の水タンクは、鉄道車両の床板2の下に固定された、断面矩形状の筒状胴体部4と、上記筒状胴体部の、少なくとも一方の開口部8を液密に塞ぐ鏡板5とよりなり、上記鏡板は、矩形板状の本体部と、該本体部の各辺の縁に折れ曲って設けられた折り曲げ板部とよりなり、上記筒状胴体部の上記開口部の端面と上記折り曲げ板部の端面とが、突合せ溶接により接合されていることを特徴とする。また、上記筒状胴体部内に固定される補強部材7や波除板9は、折れ曲り板部の正面及び背面において隅肉溶接することを特徴とする。【選択図】図1
