To provide an undersurface cover of a battery case that has achieved both a lightweight characteristic and a capability of inhibiting deformation at a time of interference with a road surface.SOLUTION: An undersurface cover 30 includes a bottom plate part 31 and a flange part 32 formed on the circumference of the bottom plate part 31. The bottom plate part 31 includes a substrate 33 on which plural joint points 35 for use in joining with a case body 11 are dispersedly arranged, and thick parts 34 which are formed as if to avoid the plural joint points 35 and whose thickness is larger than that of the substrate 33.SELECTED DRAWING: Figure 4
【課題】軽量化と、路面との干渉時における変形の抑制とを両立したバッテリーケースのアンダーカバーを提供する。【解決手段】アンダーカバー30が、底板部31と、底板部31の周縁に設けられたフランジ部32とを有する。底板部31が、ケース本体11との接合のための複数の接合点35が分散して配置された基部33と、複数の接合点35を避けて設けられ、基部33よりも大きい板厚を有する厚肉部34とを含む。【選択図】図4
