The present invention provides a vehicle body sound insulation structure capable of effectively reducing road noise generated in a wheel cover by using a relatively small number (or volume) of sound insulation members, thereby improving quietness in a vehicle at a low cost. This sound insulation structure (Sp) for a vehicle body blocks noise from the outside of the vehicle cabin, and is provided with: a window panel (24) fixed to a window frame (22) on the side of the vehicle body (10); an interior material (50) that is provided on the vehicle interior side of the window frame (22) and that has an upper end section (52) that extends obliquely upward in the direction approaching the window panel (24); and a sound insulation member (60) fixed to the upper end portion (52) of the interior material (50). Furthermore, the sound insulation member (60) is disposed so as to abut against the inner surface of the window panel (24) in a compressed state so as to block a gap (G) formed between the upper end portion (52) of the interior material (50) and the window panel (24).
本发明提供一种车身隔音结构,能够利用相对少量(或体积)的隔音部件来有效地降低在轮罩内产生的道路噪音,从而以低成本来提升车内的安静度。本发明的车身隔音结构Sp,阻断来自车厢外的噪音,且具备:窗板24,其固定于车身10的侧部的窗框22;内饰材料50,其设置于前述窗框22的车厢内侧,且具有朝向接近前述窗板24的方向而向上倾斜地延伸的上端部52;及,隔音部件60,其固定于前述内饰材料50的上端部52;并且,前述隔音部件60以堵住被形成于前述内饰材料50的上端部52与前述窗板24之间的间隙G的方式,在压缩状态下抵接到前述窗板24的内表面而配设。
