To eliminate a risk of causing stress concentration at a fixing portion with a bracket in an upper case that is deformed by increase in internal pressure of a battery case in conventional fixing structure of a battery case.SOLUTION: In a fixing structure of a battery case: a battery case C fixed under a floor panel FP of a vehicle includes a lower case LC and an upper case UC; a bracket 1 fixing the upper case UC to the floor panel FP includes a support part 1B which passes through the upper case UC to be fixed to the floor panel FP above a base part 1A fixed on the lower case LC side; the upper case UC includes a flange part 7 at a peripheral edge part of a through hole 6 of the support part 1B; a seal member 5 is arranged between the support part 1B and the flange part 7; and a gap S is formed between an undersurface of the floor panel FP and a top edge of the flange part 7. Thereby, stress concentration of the upper case UC is suppressed when the upper case UC is deformed by increase of internal pressure of the battery case C.SELECTED DRAWING: Figure 1 【課題】従来のバッテリケースの固定構造では、バッテリケースの内圧上昇により変形したアッパケースにおいて、ブラケットとの固定箇所に応力集中が生じる恐れがあった。【解決手段】車両のフロアパネルＦＰの下部に固定するバッテリケースＣが、ロアケースＬＣとアッパケースＵＣを備え、フロアパネルＦＰにアッパケースＵＣを固定するブラケット１が、ロアケースＬＣ側に固定する基部１Ａの上側に、アッパケースＵＣを貫通してフロアパネルＦＰに固定する支持部１Ｂを備え、アッパケースＵＣが、支持部１Ｂの貫通穴６の周縁部にフランジ部７を有し、支持部１Ｂとフランジ部７との間にシール部材５を介装し、フロアパネルＦＰの下面とフランジ部７の上端との間に隙間Ｓを形成した構成により、バッテリケースＣの内圧上昇によりアッパケースＵＣが変形した際、アッパケースＵＣにおける応力集中を抑制する。【選択図】図１
