PROBLEM TO BE SOLVED: To reduce ventilation resistance in a curved part of a vent pipe for a vehicle.SOLUTION: An air-conditioning duct 20 is formed into a circular pipe shape and has an internal wall surface 21 constituted of an insulation body. The air-conditioning duct 20 includes a curved part 22b that is curved. Of the curved part 22b, a half-divided part on an inner side of a curve relative to a central axis S of the curved part 22b is provided with a negatively charged electret part 24.SELECTED DRAWING: Figure 2
【課題】車両用通気管の湾曲部における通気抵抗を低減する。【解決手段】空調ダクト20は、円管状に形成されるとともに内壁面21が絶縁体で構成されている。空調ダクト20は湾曲した湾曲部22bを備えている。湾曲部22bのうち、湾曲部22bの中心軸Sよりも湾曲の内側の半割部分には、負に帯電したエレクトレット部24が設けられている。【選択図】図2
