To protect a battery unit by suppressing break of a center side portion of a member positioned below the battery unit without inviting inconvenience such as weight increase in a vehicle body.SOLUTION: In a lower structure of an electric vehicle mounted with a battery unit 12 below a floor 11, battery modules 21 of the battery unit 12 are arranged on the left and right across a tunnel part 13b swelling upward in such a manner that a cross section is formed into a substantially arch shape in a center in a vehicle width direction of the floor 11, and extending in a vehicle longitudinal direction. A transverse frame 62 provided below the battery unit 12 is mounted so as to be bridged between floor frames 15 as skeleton members positioned in the outside in a vehicle width direction from the battery unit 12 and extending in a vehicle longitudinal direction, and a portion of the transverse frame 62 opposite to the tunnel part 13b is mounted on the tunnel part 13b.SELECTED DRAWING: Figure 1

    【課題】車体の重量増加のような不都合を招来することなく、バッテリユニットの下に位置する部材の中央側部位の折れを抑制してバッテリユニットを保護する。【解決手段】フロア11下方にバッテリユニット12が取り付けられる電動車両の下部構造において、バッテリユニット12のバッテリモジュール21を、フロア11の車幅方向中央で横断面略アーチ状に上方に向けて膨出し車両前後方向に延びるトンネル部13bを挟んで左右に配設する。バッテリユニット12の下に備える横フレーム62は、バッテリユニット12より車幅方向外側に位置して車両の前後方向に延びる骨格部材であるフロアフレーム15間に橋渡しするように取り付け、横フレーム62のトンネル部13b対向部位をトンネル部13bに対して取り付ける。【選択図】図1
