PROBLEM TO BE SOLVED: To provide a sound absorption structure of an automobile door which dampens sound entering between door panels efficiently.SOLUTION: In the sound absorption structure of the automobile door which is provided with a sound absorption material inside an automobile door 100, it erects the sheet-like sound absorption material 30 between a door outer panel 101 constituting the door 100 and a door inner panel 102. It is formed with a drain hole R which exhausts water inside the door 100 on a bottom between the door outer panel 101 and the door inner panel 102 and fixes the sound absorption material 30 by inserting a projection piece 42 being provided on the sound absorption material 30 separately and extending downward into the drain hole R without plugging the drain hole R completely.SELECTED DRAWING: Figure 1
【課題】ドアパネル間に進入した音を効率良く減衰させる自動車ドアの吸音構造を提供する。【解決手段】自動車ドア100の内部に吸音材が設けられた自動車ドアの吸音構造であって、前記ドア100を構成するドアアウターパネル101とドアインナーパネル102の間にシート状の吸音材30を立設させる。ドアアウターパネル101とドアインナーパネル102の間の底部にはドア100内の水を排出する水抜き孔Rが形成され、吸音材30に別体で設けられ下方に延びる突出片42を、水抜き孔Rを完全に塞ぐことなく水抜き孔Rに差し込んで吸音材30を固定する。【選択図】図1
