To provide a lower structure of an electric vehicle which can suppress vertical vibration and twisting caused by an input load from a front suspension.SOLUTION: A lower structure body 4 of an electric vehicle 1 comprises: a battery case section 41 which can internally accommodate a battery unit B; a suspension frame section 42 which is disposed in a vehicle front side of the battery case part 41 and to which a pair of left and right suspension arms are attached at both sides in the vehicle width direction; and a connection section 43 which extends from a front end section 41a of the battery case section 41 towards each of the suspension arm attachment positions 42a of the suspension frame part 42 and connects together the battery case section 41 and the suspension frame section 42. The connection section 43 extends in the vehicle width direction across the width of the suspension frame section 42 in the vehicle width direction and extends in the vehicle vertical direction across the thickness of the suspension frame section 42 in the vehicle vertical direction.SELECTED DRAWING: Figure 1

    【課題】フロントサスペンションからの入力荷重によって生じる上下振動やねじれを抑制することができる電動車両の下部構造を提供する。【解決手段】電動車両1の下部構造体4は、電池ユニットBを内部に収容可能な電池ケース部41と、電池ケース部41の車両前方側に配置され、左右一対のサスペンションアームが車幅方向両側部に取り付けられるサスペンションフレーム部42と、電池ケース部41の前端部41aからサスペンションフレーム部42の各サスペンションアーム取付箇所42aに向かって延びており、電池ケース部41とサスペンションフレーム部42を連結する連結部43と、を備えている。連結部43は、サスペンションフレーム部42の車幅方向の幅にわたって車幅方向に延びているとともに、サスペンションフレーム部42の車両上下方向の厚さにわたって車両上下方向に延びている。【選択図】図1
