PROBLEM TO BE SOLVED: To provide a sound insulation structure for motorcar belt line part and motorcar door glass capable of improving sound insulation condition in a motorcar under a state where the door glass is closed.SOLUTION: There is provided sound insulation structure along with motorcar belt line for sound insulation between a door panel and a door glass. The door panel comprises 2 panel plates facing each other. The door glass is arranged between 2 panel plates. The panel plates respectively comprise seal member at a region along with the belt line. The door glass comprises a door glass main body and first viscoelastic member at lower section on one main surface thereof, in which the first viscoelastic member has lower Young's modulus than a seal member positioned on a main surface side of one door glass main body. The seal member positioned on one main surface side comprises 2 or more lip parts on the side of the door glass. Under a state where the door glass is closed, the first viscoelastic member is positioned between 2 lip parts while contacting to at least one part of the seal member positioned at one main surface side.SELECTED DRAWING: Figure 2A

    【課題】ドアガラスの閉時における自動車内の遮音状態を高いレベルに向上可能な自動車のベルトライン部遮音構造および自動車用ドアガラスの提供。【解決手段】自動車のベルトラインに沿ってドアパネルとドアガラスとの間を遮音する遮音構造であって、ドアパネルは互いに対向する2枚のパネル板を備え、ドアガラスは2枚のパネル板の間に配設され、パネル板はそれぞれベルトラインに沿った領域にシール部材を有し、ドアガラスはドアガラス本体とその一方の主面の下方部にドアガラス本体の一方の主面側に位置するシール部材よりヤング率の低い第1の粘弾性部材を備え、一方の主面側に位置するシール部材はドアガラス側に2以上のリップ部を有し、ドアガラスの閉時に、第1の粘弾性部材は、一方の主面側に位置するシール部材の少なくとも一部に当接しながら2つのリップ部の間に位置する自動車のベルトライン部遮音構造。【選択図】図2A
