To achieve both a high efficiency draining and reliability in inhibition of a foreign material immersion with a powerful and simple structure.SOLUTION: In a state of blocking four drain holes 5 with a non-woven fabric 14, a fixed bolt 11 is screwed and tightened to a screw hole 12 via a washer 15, and the non-woven fabric 14 is fixed from an external side to a bottom face 1a of a battery pack 1. Condensate water or the like drained in an inner part of the battery pack 1 is drained in the non-woven fabric 14 so as to be discharged from the four drain holes 5, and further, is discharged from a gap part 16 of the washer 15.SELECTED DRAWING: Figure 1
【課題】強固で簡単な構成で、効率の良い排水と、異物侵入の阻止の確実性とを両立させる。【解決手段】不織布14で4個のドレン穴5を塞いだ状態で、ワッシャ15を介して固定ボルト11をねじ穴12に螺合して締め付け、電池パック1の底部1aの底面に外側から不織布14を固定し、電池パック1の内部に溜まった凝縮水等を、4個のドレン穴5から排出して不織布14に貯留し、更に、ワッシャ15の隙間部16から排水する。【選択図】図1
