PROBLEM TO BE SOLVED: To protect a battery unit body and secure the accessibility in maintenance of a unit component.SOLUTION: A battery unit of an electric vehicle includes: a battery unit body 4 held by a chassis frame 1; a side guard part 5 which protects the battery unit body 4 from the outer side in a vehicle width direction; and a support part 6B which is coupled to a vehicle body side fixing position, supports the side guard part 5, and has an impact absorption structure 8 which absorbs an impact from the outer side in the vehicle width direction. The impact absorption structure 8 includes: a vehicle body side rail 71; a guard side rail 72 which is movable in the vehicle width direction; a fastening member 73 which fastens the vehicle body side rail to the guard side rail and ruptures when being subject to an impact to enable the guard side rail to move to the inner side in the vehicle width direction; and an impact absorber 74 which contacts with the guard side rail moved to the inner side in the vehicle width direction and absorbs the impact.

    【課題】バッテリユニット本体を保護すると共に、ユニット構成部品のメンテナンスにおけるアクセス性を確保することができるようにする。【解決手段】シャーシフレーム1に保持されるバッテリユニット本体4と、バッテリユニット本体4を車幅方向外側から保護するサイドガード部5と、車体側の固定箇所に結合されサイドガード部5を支持し、車幅方向外側からの衝撃を吸収する衝撃吸収構造8を有する支持部6Bと、を備え、衝撃吸収構造8は、車体側レール71と、車幅方向に可動なガード側レール72と、車体側レールとガード側レールとを締結し、衝撃が加わると破断しガード側レールを車幅方向内側に可動にする締結部材73と、車幅方向内側に移動したガード側レールと当接し衝撃を吸収する衝撃吸収体74と、を有する。【選択図】図1
