To provide a vehicular soundproof sheet material which does not need means for adhesion to a floor panel and is less likely to be lifted from the floor panel by vertical vibration.SOLUTION: A vehicular soundproof sheet material 10 is formed by a rubber material and placed on an upper surface of a floor panel 11 having a protruding part in a vehicle. The vehicle soundproof sheet material 10 has: a sheet material rear surface 21 having a shape which follows the upper surface of the floor panel 11; and a sheet material surface 22 having a shape which follows the sheet material rear surface 21.SELECTED DRAWING: Figure 2
【課題】フロアパネルとの接着のための手段を必要とせず、上下方向の振動に対してフロアパネルから浮き上がり難い車両用防音シート材の提供にある。【解決手段】ゴム系材料により形成され、車両における凸部を有するフロアパネル11の上面に載置される車両用防音シート材10において、車両用防音シート材10は、フロアパネル11の上面に倣う形状のシート材裏面21と、シート材裏面21に倣う形状のシート材表面22と、を有した。【選択図】 図2
