To provide a duct structure which enables improvement of sound absorption performance of a duct member formed of non-woven fabric.SOLUTION: An air intake duct 13 is connected to a fan 12 which blows cooling air to a battery module 11 mounted on a vehicle V. The air intake duct 13 includes a downstream side duct member 40 formed of non-woven fabric. The downstream side duct member 40 has a horizontal flow passage 410 disposed above the fan 12. An upper wall part 411, which faces the fan 12, of a wall part partitioning the horizontal flow passage 410 is provided with a thick part 46. A thickness of the downstream side duct member 40 in the thick part 46 is larger than a thickness of the downstream side duct member 40 around the thick part 46.SELECTED DRAWING: Figure 6

    【課題】不織布で形成されたダクト部材の吸音性能を向上させることができるダクト構造を提供する。【解決手段】吸気ダクト13は、車両Vに搭載されるバッテリモジュール11に冷却風を送風するファン12に接続される。吸気ダクト13は、不織布により形成された下流側ダクト部材40を備える。下流側ダクト部材40は、ファン12の上方に配置された水平流路410を有し、水平流路410を区画する壁部のうちファン12に対向する上壁部411には、肉厚部46が設けられている。肉厚部46における下流側ダクト部材40の厚さは、肉厚部46の周囲における下流側ダクト部材40の厚さよりも大きい。【選択図】図6
