To inhibit input of a buffer load from a cross member deformed during a lateral collision to a battery pack in a vehicle in which the battery pack is mounted under a floor.SOLUTION: A center floor cross member 36 is provided extending in a lateral direction of a vehicle so as to traverse an area above a battery pack 14. The cross member 36 has inclined parts 42L, 42R which get higher to a center at a right half and a left half. During a lateral collision, the inclined part 42L (or 42R) transmits a buffer load to a center part 40 and pushes up the center part 40, and the cross member 36 bends upward. The structure inhibits deformation to the battery pack 14 to inhibit input of the buffer load to the battery pack 14.SELECTED DRAWING: Figure 6

    【課題】バッテリパックをフロア下に搭載した車両において、側面衝突時に変形したクロスメンバからバッテリパックへの衝突荷重の入力を抑制する。【解決手段】センタフロアクロスメンバ36は、バッテリパック14の上方を横切るように車両の左右方向に延びて設けられている。クロスメンバ36は、右半分および左半分のそれぞれに中央に向けて高くなる傾斜部42L,42Rを有する。側面衝突時、傾斜部42L(または42R)が衝突荷重を中央部40に伝え、中央部40を押し上げ、クロスメンバ36は上方に向けて屈曲する。これにより、バッテリパック14に向けた変形が抑えられ、バッテリパック14への衝突荷重の入力が抑制される。【選択図】図6
