ABSORBER ATTACHMENT STRUCTURE

To make an easy absorber attachment work while appropriately maintaining an absorber attachment state.SOLUTION: A flat-plate-shaped absorber 4 formed of a resin foam material is attached to an attachment region S provided on the inner peripheral surface of a component 3 of a ventilation path. The absorber 4 has a rectangular shape when viewed from the side of the ventilation path, and an engagement claw 32 provided on a corner part of the circumference of the absorber 4 is engaged with an absorber circumference and holds the absorber 4 in a direction perpendicular to the attachment region. In a portion of the side of the absorber circumference, the absorber 4 is provided with a notch 41 toward inside of the absorber. The component 3 of the ventilation path is provided with a projection member 33 into a shape matching the notch 41 of the absorber, and the projection member 33 comes in contact with the notch 41 of the absorber and regulates relative movement in a direction along the side of the absorber.SELECTED DRAWING: Figure 2 【課題】 吸音材の取付状態を適切に維持可能としつつ、吸音材の取付作業を簡単にする。【解決手段】 通気経路の構成部材３の内周面に設けられた取付領域Ｓに、樹脂発泡材からなる平板状の吸音材４が取付けられる。吸音材４は、通気経路の側から見て矩形状であり、吸音材４の周縁のコーナー部に設けられた係止爪３２が吸音材周縁に係止して、吸音材４を取付領域面直方向に保持している。吸音材周縁の辺の部分において、吸音材４には、吸音材の内側に向かって切欠き４１が設けられている。通気経路の構成部材３には、吸音材の切欠き４１に合致する形状に突起部材３３が設けられており、突起部材３３が吸音材の切欠き４１に当接して、吸音材の辺に沿う方向の相対的な動きを規制する。【選択図】 図２
