To provide a vibration suppression structure of a battery pack which can suppress vibration of a blower fan without increasing the weight of the battery pack.SOLUTION: A placement member 91 on which a blower fan 55 is placed is disposed above a lower surface of a battery case 21. An air duct 70 has: a first duct member 71 extending in a vehicle width direction; a second duct member 73 extending in a vehicle fore and aft direction; and a middle duct member 72 connected to the first duct member 71 and the second duct member 73. The middle duct member 72 has a vehicle width direction extension part 72A extending in the vehicle width direction and connected to the first duct member 71. The vehicle width direction extension part 72A has a placement member attachment part 94 fixed to the placement member 91. The second duct member 73 has a battery case attachment part 80 fixed to the battery case 21. The placement member attachment part 94 and the battery case attachment part 80 are disposed at positions which are different in the vehicle fore and aft direction and the vehicle width direction.SELECTED DRAWING: Figure 2
【課題】バッテリパックの重量を増加させることなく送風ファンの振動を抑制できるバッテリパックの振動抑制構造を提供すること。【解決手段】送風ファン55が載置される載置部材91はバッテリケース21の下面よりも上方に配置されている。送風ダクト70は、車両幅方向に延びる第1ダクト部材71と、車両前後方向に延びる第2ダクト部材73と、第1ダクト部材71と第2ダクト部材73とに接続される中間ダクト部材72とを有する。中間ダクト部材72は、車両幅方向に延びて第1ダクト部材71に接続される車両幅方向延伸部72Aを有する。車両幅方向延伸部72Aは、載置部材91に固定される載置部材取付部94を有する。第2ダクト部材73は、バッテリケース21に固定されるバッテリケース取付部80を有する。載置部材取付部94とバッテリケース取付部80とが、車両前後方向および車両幅方向で異なる位置に配置されている。【選択図】図2
