Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a structure in which there is no risk of occurrence of a tightening failure when a tank leg and a case leg of a hot water storage device are connected by a connecting bolt.SOLUTION: As illustrated in Figure (b), a plate 50 corresponding to a nut comprises a dowel 63 for turning prevention. As illustrated in Figure (c), the plate 50 is inserted under a center piece 31a, a left piece 31b, and a right piece 31c so that the dowel 63 is fitted in a slit 62. When a connecting bolt 16 is tightened, the plate 50 starts to turn clockwise. However, because the dowel 63 for plate turning prevention is fitted in the slit 62 between the left piece 31b and the right piece 31c, the plate 50 is restrained from turning, and a tightening failure can be prevented from occurring.SELECTED DRAWING: Figure 9 【課題】貯湯装置のタンク脚と筐体脚とを連結ボルトで連結するに当たり、締め付け不良が発生する心配のない構造を提供する。【解決手段】図（ｂ）に示すように、ナットに相当するプレート５０に、旋回防止用のダボ６３を備えている。図（ｃ）に示すように、スリット６２にダボ６３が嵌るようにして、中央片３１ａ、左片３１ｂ及び右辺３１ｃの下にプレート５０を挿入する。連結ボルト１６を締めると、プレート５０が右旋回を開始するが、プレート旋回防止用のダボ６３が、左片３１ｂと右辺３１ｃとの間のスリット６２に嵌っているため、プレート５０の旋回が抑制され、締め付け不良の発生を防止することができる。【選択図】図９
