PROBLEM TO BE SOLVED: To restrain dropping of an adsorbent with a simple configuration.SOLUTION: An intake duct includes a duct body 10 formed and split in a circumferential direction by a pair of split bodies 11 and 12. The split bodies 11 and 12 are formed of a laminated member which includes a first fiber layer 13, a second fiber layer 14 provided on an outer peripheral side of the first fiber layer 13, and an adsorbent layer 17 interposed between the first fiber layer 13 and the second fiber layer 14 and having an adsorbent 16 adsorbing fuel vapor of an internal combustion engine. A joining portion 20 made of resin is provided between the one split body 11 and the other split body 12 so as to join the split bodies with each other and to cover end surfaces 11A and 12A exposing the adsorbent 16 in the split bodies 11 and 12.SELECTED DRAWING: Figure 3

    【課題】吸着剤の脱落を簡単な構成により抑制することができる。【解決手段】吸気ダクトは、一対の分割体11,12により周方向に分割して形成されたダクト本体10を備えている。各分割体11,12は、第1繊維層13と、第1繊維層13の外周側に設けられた第2繊維層14と、第1繊維層13と第2繊維層14との間に介在され、内燃機関の燃料蒸気を吸着する吸着剤16を有する吸着剤層17とを含む積層部材により形成されている。一方の分割体11と他方の分割体12との間には、互いを接合するとともに分割体11,12における吸着剤16の露出する端面11A,12Aを被覆する樹脂製の接合部20が設けられている。【選択図】図3
