To provide a vehicular ventilation duct which absorbs sound and gets rid of odors.SOLUTION: A vehicular ventilation duct 10 includes: a duct body 12 configured so that air can circulate through a ventilation passage T; an on-off valve 14 which is attached to the duct body 12 and may open or close the ventilation passage T so as to allow circulation of air to the vehicle outer side; and an absorber 16 which is disposed so as to face a vent hole 12a which is closed by the on-off valve 14 in the ventilation passage T. The absorber 16 contains fibrous active carbon, and one surface facing the ventilation passage T side has air permeability higher than that of the other surface opposite to the one surface.SELECTED DRAWING: Figure 2
【課題】吸音と共に消臭も行う。【解決手段】車両用ベントダクト10は、通気路Tを通して空気が流通可能に構成されたダクト本体12と、ダクト本体12に取り付けられ、車両外側への空気の流通を許容するように通気路Tを開閉可能な開閉弁14と、通気路Tにおける開閉弁14で閉じられる通気口12aに対向するように配置された吸収体16とを備えている。吸収体16は、繊維状活性炭を含み、通気路T側に臨む一面の方が、この一面と反対側の他面よりも通気性が高くなっている。【選択図】図2
