PROBLEM TO BE SOLVED: To suppress inflow of a liquid to an air intake duct and reduce failure of a cooling blower due to the liquid.SOLUTION: A cooling unit of a vehicular battery pack comprises: an air intake duct having an intake port 61 opening upward at an upper position from a cooling blower; and a cover member 65 arranged above the air intake port 61. The cover member 65 includes: a top plate 65a which is separated upward from an end face H of the air intake port 61, and covers the air intake port 61; and a side plate 65b which is separated from a side face of the air intake port 61, and extends from a side edge of the top plate 65a downward from the end face H of the air intake port 61. An air intake passage of the air intake duct is formed in a labyrinth structure in which the periphery of the air intake port 61 is covered with the top plate 65a and the side plate 65b.SELECTED DRAWING: Figure 6

    【課題】吸気ダクトへの液体の流入を抑制し、液体による冷却ブロアの故障を低減する。【解決手段】冷却ブロワよりも上方位置において上方に向かって開口する吸気口61を備えた吸気ダクトと、吸気口61の上方に配置されたカバー部材65とを備え、カバー部材65は、吸気口61の端面Hより上方に離間し、吸気口61を覆う天板65aと、吸気口61の側面から離間し、天板65aの側縁から吸気口61の端面Hより下方に延びている側板65bとを含み、この天板65a及び側板65bによって吸気口61の周囲を覆って吸気ダクトの吸気通路がラビリンス構造となっている。【選択図】図6
