PROBLEM TO BE SOLVED: To provide a grommet that can increase sound-reducing effect by a sound insulation wall, and can exert high sound insulation performance without impairing moldability and releasability of a grommet body.SOLUTION: Inside a grommet body 10 which is formed of rubber or the like, an annular corrugated sound insulation wall 30 which partitions an internal space of the grommet body into two tightly closed air chambers S1, S2 is provided by connecting an outer peripheral end 31 to an inner periphery of large-diameter cylindrical part 11, and tightly attaching an inner peripheral end 32 to an outer periphery of an electric wire W. The grommet body 10 is separated into two divided grommet bodies 10A, 10B, and the bodies can be engaged with each other by engaging parts 21, 22.SELECTED DRAWING: Figure 1

    【課題】グロメット本体の成形性や離型性を損なうことなく、遮音壁による減音効果を高めることができて、高い遮音性能を発揮することのできるグロメットを提供する。【解決手段】ゴム等で成形されたグロメット本体10の内部に、外周端31が、大径筒部11の内周に結合され、内周端32が、電線Wの外周に密着することにより、グロメット本体の内部空間を2つの密閉された空気室S1、S2に仕切る環状の波形遮音壁30を設けた。グロメット本体10は、2つの分割グロメット本体10A、10Bに分離し、係合部21、22で係合できるようにした。【選択図】図1
