To provide a high-rigid and lightweight battery cover.SOLUTION: A battery cover 100 which covers an upper part of an on-vehicle battery comprises: a rectangular top plate 10 including a first symmetry axis S1 and a second symmetry axis S2 which is orthogonal to the first symmetry axis S1; and a peripheral edge wall 20 provided at a peripheral edge of the top plate 10. The top plate 10 includes: a base plate part 11 including a reference surface 11b; and a first reinforcement part P1 expanding from the reference surface 11b and including a first vertical wall 12 and a first horizontal wall 13. The first vertical wall 12 is along a first annular form F1 which is closed while surrounding a centroid C of the top plate 10. The first annular form F1 includes: a third symmetry axis S3 which overlaps the first symmetry axis S1 in parallel therewith; and a fourth symmetry axis S4 which overlaps the second symmetry axis S2 in parallel therewith and orthogonal to the third symmetry axis S3.SELECTED DRAWING: Figure 2
【課題】高剛性で軽量なバッテリーカバーを提供する。【解決手段】車載バッテリーの上部を覆うバッテリーカバー100は、第1対称軸S1及び第1対称軸S1に直交する第2対称軸S2を有する矩形状の天板10と、天板10の周縁部に設けられる周縁壁20と、を備える。天板10は、基準面11bを有するベース板部11と、基準面11bから膨出し、第1縦壁12及び第1横壁13を有する第1補強部P1と、を有する。第1縦壁12は、天板10の図心Cを囲んで閉じる第1環形状F1に沿う。ここで、第1環形状F1は、第1対称軸S1に並行して重なる第3対称軸S3と、第2対称軸S2に並行して重なり第3対称軸S3に直交する第4対称軸S4を有する。【選択図】図2
