To have a suspension member hard to collide with a battery at the time of front collision of a vehicle.SOLUTION: A vehicle lower unit structure includes: a battery unit 18 provided below a floor of a passenger compartment; and a suspension member 16 provided in front of the passenger compartment and in front of the battery unit 18. A floor side expansion member 36 having a front end inclined surface and a battery side expansion member 50 having a front end inclined surface are provided on a floor side, a member side expansion member 34 having a rear end inclined surface with a lower side on the rear side is provided on a suspension member side and the suspension member 16 and the floor side are connected by a bracket 60. In addition, while having the rear end inclined surface of the member side expansion member 34, the front end inclined surface of the floor side expansion member 36, and the front end inclined surface of the battery side expansion member 50 positioned in this order toward the vehicle rear, a front end of the bracket 60 is positioned more behind the front end inclined surface of the floor side expansion member 36.SELECTED DRAWING: Figure 4
【課題】車両前突時に、サスペンションメンバがバッテリユニットに衝突しにくくする。【解決手段】車室のフロア下に設けられたバッテリユニット18と、前記車室より前方であってバッテリユニット18の前方に設けられたサスペンションメンバ16と、を備える。フロア側に前端斜面を有するフロア側拡張部材36と、前端斜面を有するバッテリ側拡張部材50を設け、サスペンションメンバ側に後端に下方側が後方側に位置する後端斜面を有するメンバ側拡張部材34を設け、サスペンションメンバ16と、フロア側とをブラケット60で接続する。そして、車両後方に向かって、メンバ側拡張部材34の後端斜面、フロア側拡張部材36の前端斜面、バッテリ側拡張部材50の前端斜面の順で位置しているとともに、ブラケット60の前端はフロア側拡張部材36の前端斜面より後方に位置する。【選択図】図4
