To provide a vehicle body sound insulation structure which effectively reduces road noise occurring in a wheel house with a relatively small amount (or cubic volume) of a sound insulation member to improve quietness in a vehicle at low costs.SOLUTION: A vehicle body sound insulation structure Sp of the invention blocks noise from the outside of a passenger compartment and includes: a window panel 24 fixed to a window frame 22 of a side part of a vehicle body 10; an interior material 50 which is provided at the passenger compartment inner side of the window frame 22 and has an upper end part 52 which extends inclining upward in a direction toward the window panel 24; and a sound insulation member 60 fixed to the upper end part 52 of the interior material 50. The sound insulation member 60 is disposed in contact with an inner surface of the window panel 24 in a compression state so as to close a gap G formed between the upper end part 52 of the interior material 50 and the window panel 24.SELECTED DRAWING: Figure 3
【課題】本発明は、ホイールハウス内で発生したロードノイズを、比較的少ない量(または体積)の防音部材で有効に低減して、車内の静粛性を安価に高めることができる車体防音構造を提供する。【解決手段】本発明の車体防音構造Spは、車室外からの騒音を遮断するものであって、車体10の側部の窓枠22に固定される窓パネル24と、前記窓枠22の車室内側に設けられ、前記窓パネル24に接近する方向に向かって上向き傾斜で延在する上端部52を有する内装材50と、前記内装材50の上端部52に固定される防音部材60と、を備え、前記防音部材60は、前記内装材50の上端部52と前記窓パネル24との間に形成される隙間Gを塞ぐように、前記窓パネル24の内面に圧縮状態で当接させて配設される。【選択図】図3
