To provide a floor silencer for a vehicle which can prevent an urethane foam raw material from oozing out to a skin material and is lighter weight.SOLUTION: A floor silencer 10A for a vehicle is composed of a skin material 20A and an urethane foam which is formed by foaming an urethane foam raw material 30A while being brought into contact with one surface of the skin material, and being bonded to the skin material. The skin material is composed of an outer foam fiber sheet foamed by impregnating an outer fiber sheet having a fiber diameter of larger than 4 d (denier) and a basis weight of 130-250 g/m2 with a foam resin, which prevents the urethane foam raw material from oozing out from an outer surface (design surface) of the skin material, is lightweight, and is excellent in abrasion resistance and sound absorption characteristics.SELECTED DRAWING: Figure 1
【課題】表皮材にウレタンフォーム原料が染み出すのを防ぐことができ、より軽量な車両用フロアサイレンサーを提供する。【解決手段】表皮材20Aと、表皮材の一方の面にウレタンフォーム原料30Aが接触しながら発泡し、表皮材と接着して形成されたウレタンフォームとよりなる車両用フロアサイレンサー10Aであって、表皮材は、繊維径が4d(デニール)より大で、目付量が130〜250g/m2の外側の繊維シートに、発泡樹脂が含浸して発泡した外側発泡繊維シートで構成することにより、表皮材の外側表面(意匠面)からウレタンフォーム原料が染み出すのを防ぎ、軽量で、耐摩耗性や吸音特性に優れる。【選択図】図1
