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 10 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 10, and the end of an edge of the inner cross member 20 outside in the width direction is joined to the inner face of the side wall 13.SELECTED DRAWING: Figure 7
【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10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10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の幅方向外側の端部の縁が、側壁部13の内面に接合されている。【選択図】図7
