PROBLEM TO BE SOLVED: To provide a vehicle soundproof structure which inhibits noise entering from an opening of a sound absorption material and vibration of a panel.SOLUTION: A vehicle soundproof structure 1 includes a panel 20 which partitions the interior and the exterior of a vehicle compartment from each other, a sound absorption material 10 arranged along a vehicle compartment side surface of the panel 20, and a fixing member 30 which sandwiches the sound absorption material 10 with the panel 20. The sound absorption material 10 has an opening 10b and has a deformed portion 12, which is pressed and compressively deformed between the fixing member 30 and the panel 20, at a periphery of the opening 10b.SELECTED DRAWING: Figure 2
【課題】吸音材の開口から侵入するノイズとパネルの振動を抑制することのできる自動車用防音構造を提供する。【解決手段】自動車用防音構造1は、車室内外を隔てるパネル20と、パネル20の車室側の面に沿って配置される吸音材10と、パネル20との間で吸音材10を挟持する固定部材30と、を有している。吸音材10は開口10bを備えるとともに、開口10bの周辺に、固定部材30とパネル20との間で押圧されて圧縮変形された変形部12を有する。【選択図】図2
