To provide a battery case structure which improves heat resistance while suppressing increase in weight.SOLUTION: A battery case structure comprises: a battery which is provided on the lower side of a floor panel of a vehicle; a lower case which covers the battery from the lower side; and an upper case 4 which has a horizontal plate part 11 arranged between the floor panel and the battery and covers the battery from the upper side. The thickness t2 along the vertical direction of an outer peripheral part 20 of the horizontal plate part 11 in the upper case 4 is thicker than the thickness t1 along the vertical direction of an inner peripheral part 30 of the horizontal plate part 11. The upper case 4 is formed into a plate shape with a metallic material. A plate-like reinforcement member 25 is attached to the outer peripheral part 20.SELECTED DRAWING: Figure 4

    【課題】重量の増加を抑えつつ、耐熱性を向上したバッテリケース構造を提供する。【解決手段】バッテリケース構造は、車両のフロアパネルの下方に設けられるバッテリと、バッテリを下方から覆う下部ケースと、フロアパネルとバッテリとの間に配置される水平プレート部11を有し、バッテリを上方から覆う上部ケース4と、を備える。上部ケース4における水平プレート部11の外周部20の上下方向に沿う厚みt2は、水平プレート部11の内周部30の上下方向に沿う厚みt1よりも厚い。上部ケース4は、金属製の材料により板状に形成され、外周部20には、板状の補強部材25が取り付けられている。【選択図】図4
