To provide a vehicular lower part structure which inhibits battery units from being sandwiched between a connection member and a side sill to be deformed at a side collision of a vehicle and inhibits an underfloor travel wind from entering the battery units.SOLUTION: A vehicular lower part structure includes: a side sill 1 extending in a vehicle fore-and-aft direction on an outer side in a vehicle width direction; a first battery unit 21 and a second battery unit 22 which are provided adjacent to an inner side in the vehicle width direction of the side sill 1 and spaced apart from each other in the vehicle width direction below a floor panel 8; and a connection member 60 which connects between the first battery unit 21 and the second battery unit 22. The connection member 60 includes: a vertical wall part 62 extending in the vehicle width direction and protruding to a vehicle lower side; and a slope part 64 which inclines to the vehicle lower side as it goes rearward in the rear of the vertical wall part 62. A lower end of the slope part 64 is located at the vehicle lower side relative to a lower end of the vertical wall part 62.SELECTED DRAWING: Figure 7
【課題】車両側突時に、バッテリユニットが連結部材とサイドシルとの間に挟まれて変形することを抑制し、かつ、床下走行風がバッテリユニット間に入り込むのを抑制する車両の下部構造を提供する。【解決手段】車幅方向外側において車両前後方向に延びるサイドシル1と、サイドシル1の車幅方向内側に隣接してフロアパネル8の下方において車幅方向に離間して設けられる第1バッテリユニット21および第2バッテリユニット22と、第1バッテリユニット21と第2バッテリユニット22との間を連結する連結部材60と、を備え、連結部材60は、車幅方向に延びて車両下方に突出する縦壁部62と、縦壁部62の後方において後方ほど車両下方に傾斜するスロープ部64と、を備え、スロープ部64の下端は縦壁部62の下端よりも車両下方に位置するように構成されたことを特徴とする。【選択図】図7
