PROBLEM TO BE SOLVED: To improve sound-insulating properties, in a sound-insulating structure for a panel where a sound-absorbing material formed with a fiber is mounted between an outer panel and an inner panel.SOLUTION: A sound-insulating structure for a panel includes: a floor panel (an outer panel) 1; a vehicle inside panel (an inner panel) 16; and a sound-absorbing material 20 mounted between the floor panel 1 and the vehicle inside panel 16. The sound-absorbing material 20 consists of a laterally woven fiber layer 21 on a side of the floor panel 1, and a longitudinally woven fiber layer 22 on a side of the vehicle inside panel 16. The vehicle inside panel is separated into a plurality of small spaces through partition panels placed in a space between a first panel and a second panel. Each small space is communicated with the side of the longitudinally woven fiber layer 22 through a communication hole.SELECTED DRAWING: Figure 10
【課題】外側パネルと内側パネルの間に繊維からなる吸音材を配置したパネル遮音構造において、遮音特性を向上させる。【解決手段】パネル遮音構造は、フロアパネル(外側パネル)1と、車内側パネル(内側パネル)16と、フロアパネル1と室内側パネル16の間に配置された吸音材20とからなる。吸音材20は、フロアパネル1側の横織繊維層21と、室内側パネル16側の縦織繊維層22とから構成される。車内側パネルは、第1パネル部と第2パネル部との間の空間に配設した仕切板部によって、複数の小空間が区画される。各小空間は、連通孔を介して、縦織繊維層22側と連通される。【選択図】図10
