To provide an automobile battery case protection structure and a floor cross-member which suppress deformation of a battery case in the side crash, enables weight reduction of vehicle body without reducing a cabin volume or reducing flexibility of the vehicle design, and has excellent vibration-damping properties.SOLUTION: An automobile battery case protection structure 1 according to the present invention comprises: a floor 3; a battery case 5; a pair of side sills 7; and a floor cross-member 9 provided on an upper surface of the floor 3 so as to cross over the battery case 5 in a vehicle width direction and protrude out farther than the battery case 5 on both sides in the vehicle width direction. The floor cross member 9 comprises: a hat cross-section member 13 having a top plate 13a, vertical walls 13b and flanges 13c; a resin 15 affixed or applied to at least the inner surface and/or outer surface of the vertical walls 13b of the hat cross-section member 13; and a reinforcing plate 17 laid out to cover the resin 15 and bonded to the resin 15.SELECTED DRAWING: Figure 1

    【課題】側面衝突時のバッテリーケースの変形を抑制し、軽量化が可能で、キャビン容積を低下させたり車両設計の自由度を低下させたりすることなく、制振性にも優れる自動車のバッテリーケース保護構造及びフロアクロスメンバを提供する。【解決手段】本発明に係る自動車のバッテリーケース保護構造1は、フロア3と、バッテリーケース5と、一対のサイドシル7と、バッテリーケース5の上方を車幅方向に横切ってバッテリーケース5よりも車幅方向両側に突出するようにフロア3の上面に設けられるフロアクロスメンバ9とを備え、フロアクロスメンバ9は、天板部13a、縦壁部13b及びフランジ部13cを有するハット断面部材13と、ハット断面部材13の少なくとも縦壁部13bの内面及び/又は外面に貼付又は塗布された樹脂15と、樹脂15を覆うように配設されて樹脂15と接着された補強板17とを備えてなることを特徴とする。【選択図】 図1
