PROBLEM TO BE SOLVED: To provide a door hole seal material for a vehicle which prevents noise from being caused by contact with a protrusion protruding from an opening of an inner panel of a door and achieves high sound absorption performance and sound insulation effect to improve quietness in a vehicle cabin.SOLUTION: A door hole seal material 1 for a vehicle includes: a resin sheet 2; and a sheet-like foam elastic material 3. In the resin sheet 2, a through hole 2c is formed at a portion that corresponds to a protruding direction tip side of an impact absorption material 105. The sheet-like foam elastic material 3 is loose at the inner periphery side of the through hole 2c of the resin sheet 2 in a side view.SELECTED DRAWING: Figure 2
【課題】ドアのインナパネルの開口部から突出する突出物との接触よる異音の発生を招くことなく、しかも、高い吸音性能と遮音効果を発揮させて車室内の静粛性を向上させる。【解決手段】自動車用ドアホールシール材1は、樹脂製シート2とシート状発泡弾性材3とを備えている。樹脂製シート2には、衝撃吸収材105の突出方向先端側に対応する部分に貫通孔2cが形成されている。シート状発泡弾性材3は、側面視において樹脂製シート2の貫通孔2cの内周側で弛んでいる。【選択図】図2
