To improve a natural vibration frequency of an entire structure in which a battery pack is mounted.SOLUTION: A lower case 1 has a bottom plate 1a, a side plate 1b, and a flange part 1c and houses a battery stack 2. A stack pedestal 3 connects an end of the battery pack 2 with the side plate 1b. An EA material 20 is disposed facing a surface, which is opposite to a surface connected with the stack pedestal 3, of the side plate 1b. A connection member 8 has a bottom plate 8a, a side plate 8b, and a top plate 8c and is provided so as to cover an end of the EA material 20. A bulk material 7 is inserted between the connection member 8 and the side plate. A connection member 9 connects the bottom plate 1a with the bottom plate 8a. The connection member 10 connects the flange part 1c with the top plate 8c.SELECTED DRAWING: Figure 4

    【課題】電池パックを搭載する構造全体の固有振動数を向上させる。【解決手段】ロアケース1は、底板1a、側板1b及びフランジ部1cを有し、電池スタック2を収納する。スタック台座3は、電池スタック2の端部と側板1bとを連結する。EA材20は、側板1bのスタック台座3が連結された面とは反対側の面に対向して配置される。連結部材8は、底板8a、側板8b及び天板8cを有し、EA材20端部を覆うように設けられる。バルク材7は、連結部材8と前記側板との間に挿入される。連結部材9は、底板1aと底板8aとを連結する。連結部材10は、フランジ部1cと天板8cとを連結する。【選択図】図4
