To configure, with the minimum number of components, a refrigerant jacket of an upper stage battery case of a two-story battery case.SOLUTION: A recessed portion 42b recessed upward is formed in a case lower wall 42a of a second battery case 32 that is superposed on an upper side of a first battery case 31, a battery 45 is mounted on a top surface of the recessed portion 42b, and a refrigerant jacket 47 is formed between a bottom surface of the recessed portion 42b and the top surface of the first battery case 31 connected to the bottom surface. Thus, not only a refrigerant jacket 47 can be configured using existing first and second battery cases 31, 32 without adding special members, but also, even if a refrigerant leaks from the refrigerant jacket 47, there is no risk that the refrigerant enters into the inside of the first battery case 31 or the second battery case 32.SELECTED DRAWING: Figure 3

    【課題】 二階建てのバッテリケースのうち、上段のバッテリケースの冷媒ジャケットを最小限の部品点数で構成する。【解決手段】 第1バッテリケース31の上側に重ね合わされる第2バッテリケース32のケース下壁42aには上向きに窪む凹部42bが形成され、凹部42bの上面にバッテリ45が載置され、凹部42bの下面とそこに結合された第1バッテリケース31の上面との間に冷媒ジャケット47が形成されるので、特別の部材を追加することなく、既存の第1バッテリケース31および第2バッテリケース32を利用して冷媒ジャケット47を構成できるだけでなく、万一冷媒ジャケット47から冷媒が漏れた場合であっても、その冷媒が第1バッテリケース31あるいは第2バッテリケース32の内部に浸入する虞がない。【選択図】 図3
