To provide a structure of a vehicular battery pack, in which torsional rigidity is ensured while a battery pack is lightened in weight and the deformation of a battery case due to side collision, etc. can be suppressed.SOLUTION: A battery case of a battery pack 1 includes a bottom face 12 and a side wall 13 projecting above a vehicle from each of both sides of the bottom face 12 and extending in a front-back direction. An inner cross member 20 extending in a width direction is provided inside the battery case. The inner cross member 20 is joined to the bottom face 12 and the side walls on both sides. The length H1 of the inner cross member 20 in the vehicle vertical direction is set longer than the length L1 in the front-back direction. The inner cross member 20 and the bottom face 12 configure a closed cross-section structure as viewed in the width direction.SELECTED DRAWING: Figure 5

    【課題】バッテリパックを軽量化しつつねじれ剛性を確保し、側突等によるバッテリケースの変形を抑制する。【解決手段】バッテリパック1のバッテリケースは、底面部12と、底面部12の両側部から車両上方に突出し、前後方向に延びる側壁部13と、を有し、バッテリケース内には、幅方向に延びる内側クロスメンバ20が設けられ、内側クロスメンバ20は、底面部12及び両側の側壁部に接合されており、内側クロスメンバ20の車両上下方向の長さH1は、前後方向の長さL1よりも長く設定されており、内側クロスメンバ20と底面部12によって、幅方向視で閉断面構造が構成されている。【選択図】図5
