To provide a sound absorption and insulation structure which enables reduction of costs for fixing a sound absorption and insulation material and eliminates needs for noise measures.SOLUTION: A vehicle sound absorption and insulation structure utilizes a sound absorption and insulation material 2 having at least one hole punched therein and including an internal space S, which communicates with the outside through the holes, to absorb and insulate sound occurring at an interior and an exterior of a vehicle. The sound absorption and insulation material 2 is fixed to a body panel 4 by a thermosetting adhesive 1 in a state that the sound absorption and insulation material 2 covers the body panel 4 of the vehicle.SELECTED DRAWING: Figure 2
【課題】吸遮音材を固定するためのコストを低減するとともに、ノイズ対策が不要となる吸遮音構造を提供することである。【解決手段】少なくとも1個の孔が穿孔され、孔を通じて外部と連通する内部空間Sを備える吸遮音材2を利用して車両の内外で発生する音を吸遮音する車両の吸遮音構造であって、吸遮音材2が車両のボデーパネル4を覆った状態で熱硬化性の接着剤1によってボデーパネル4に固定されている。【選択図】図2
