To suppress water coverage of a battery pack.SOLUTION: A recess 31 which is a recessed part of an upper surface 21 is formed on a seat frame 20 covering the entire battery pack 10 from above, and a through hole 36 penetrating through the seat frame 20 in a vertical direction is formed on a bottom surface 32 of the recess 31. The through hole 36 is formed at a position not overlapping the battery pack 10 in plan view.SELECTED DRAWING: Figure 2 【課題】電池パックの被水を抑制する。【解決手段】電池パック１０の全体を上方から覆うシートフレーム２０に、上面２１の一部が窪んだ凹部３１が形成されており、凹部３１の底面３２にシートフレーム２０を上下方向に貫通する貫通孔３６が形成されている。貫通孔３６は、平面視において電池パック１０と重畳しない位置に形成されている。【選択図】図２
