Summary:To provide a vehicle body lower part structure which can efficiently absorb collision energy while preventing damage of a battery mounted theron when a buffer load is input.SOLUTION: A vehicle body lower part structure includes: side frames 50 each connecting a battery pack 20 disposed below a floor part 13 with a side sill 12; and a battery frame 38 supporting a battery 27 in the battery pack 20. A first joint flange 55, which is joined to a case bottom part 41, of the side frame 50 is arranged so that a second joint flange 75, which is joined to the case bottom part 41, of the battery frame 38 overlaps with the upper side of the first joint flange in a vertical direction.SELECTED DRAWING: Figure 2 【課題】衝突荷重の入力時に、搭載するバッテリの損傷を防止しつつ、衝突エネルギーを効率良く吸収することができる車体下部構造を提供する。【解決手段】車体下部構造は、フロア部13の下方に配置されるバッテリパック20とサイドシル12とを連結するサイドフレーム50と、バッテリパック20の内部でバッテリ27を支持するバッテリフレーム38と、を備える。サイドフレーム50のうちケース底部41に接合する第1接合フランジ55は、バッテリフレーム38のうちケース底部41に接合する第2接合フランジ75が上下方向において上側に重なるように配置される。【選択図】図2
