To provide a duct structure which enables improvement of seal performance in a connection portion between a first duct member formed of non-woven fabric and a second duct member different from the first duct member.SOLUTION: Cooling air for cooling a battery module 11 mounted on a vehicle V circulates in an air intake duct 13. The air intake duct 13 includes: a downstream side duct member 40 formed of non-woven fabric; an upstream side duct member 30 in which an end 35 is inserted into the downstream side duct member 40 to be connected therewith; and a seal member 50 which is provided at the end 35 of the upstream side duct member 30 and seals a space between an inner peripheral surface of the downstream side duct member 40 and an outer peripheral surface of the upstream side duct member 30. The downstream side duct member 40 has: a body 401 forming a passage; and a contact part 402 with which the seal member 50 comes into contact. A thickness of the contact part 402 is smaller than a thickness of the body 401.SELECTED DRAWING: Figure 4

    【課題】不織布で形成された第1ダクト部材と第1ダクト部材とは異なる第2ダクト部材との接続箇所におけるシール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には、車両Vに搭載されるバッテリモジュール11を冷却する冷却風が流通する。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と、端部35が下流側ダクト部材40に挿入されて接続される上流側ダクト部材30と、上流側ダクト部材30の端部35に設けられ、下流側ダクト部材40の内周面と上流側ダクト部材30の外周面との間をシールするシール部材50と、を備える。下流側ダクト部材40は、流路を形成する本体部401と、シール部材50が当接する当接部402と、を有する。当接部402の厚みは本体部401の厚みよりも小さい。【選択図】図4
