NOISE INSULATION STRUCTURE OF CABIN FLOOR |
| 摘要 |
A floor carpet is placed on a floor panel forming a cabin floor surface. The floor carpet comprises a skin layer which is configured to block an airflow therethrough and a sound-absorption layer which is made of a sound-absorption material and configured to allow an airflow therein, the sound-absorption layer being provided below the skin layer to contact the floor panel at a lower face thereof. A space between the skin layer and the floor panel (a space portion where the sound-absorption layer is arranged) is sealed with a seal member which is configured to surround the sound-absorption layer. The seal member is pressed against the floor panel (tightly) by a pressing member which is fixed to a vehicle-body side with a fixing tool. |
