PROBLEM TO BE SOLVED: To circumvent deformation of battery side connector and a casing connector, when attaching a battery pack to the casing or detaching therefrom.SOLUTION: A dilatant body 40 showing dilatancy behavior is provided on the bottom face of a casing, for example. When a battery pack 16 descends vigorously and abuts on the dilatant body 40, the dilatant body 40 shows behavior as a hard body and stops the battery pack 16 temporarily. Thereafter, the dilatant body 40 shows behavior as a soft body, and is collapsed gradually by the deadweight of the battery pack 16. Consequently, the battery pack 16 descends slowly.SELECTED DRAWING: Figure 2

    【課題】バッテリパックをケーシングに着脱する際、バッテリ側コネクタやケーシング側コネクタが変形すること等を回避する。【解決手段】ダイラタンシー挙動を示すダイラタント体40を、例えば、ケーシングの底面に設ける。ダイラタント体40は、バッテリパック16が勢いよく下降して当接したとき、硬質体としての挙動を示してバッテリパック16を一旦停止させる。ダイラタント体40は、その後、軟質体としての挙動を示し、バッテリパック16の自重によって徐々に圧潰される。従って、バッテリパック16の下降が緩慢となる。【選択図】図2
