PROBLEM TO BE SOLVED: To provide a grommet capable of facilitating mold releasing after molding and exerting high sound insulation performance.SOLUTION: An elastic material-made grommet 10 has: a large diameter cylindrical part 11 comprising a panel engagement part 12 on an outer periphery; two small diameter cylindrical parts 13, 14 disposed at both sides of the large diameter cylindrical part in an axial direction Y and tightly fitted to the outer periphery of an electric wire W, respectively; and two annular connected shield walls 15, 16 in which an outer peripheral edge is joined to the large diameter cylindrical part and an inner peripheral edge is joined to the small diameter cylindrical part. Plural platy noise barriers 20 axially extending and disposed radially leaving a space in a circumferential direction are integrally formed inside.SELECTED DRAWING: Figure 1
【課題】成形時の離型を容易に行うことができ、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】パネル係合部12を外周に備えた大径筒部11と、大径筒部の軸線方向Yの両側に配置され、電線Wの外周にそれぞれ密着嵌合する2つの小径筒部13、14と、外周縁が大径筒部に結合される共に内周縁が小径筒部に結合された2つの環状の連結遮蔽壁15、16と、を有した弾性材料製のグロメット10であって、内部に、軸線方向に沿って延在し且つ周方向に間隔をおいて放射状に配された複数の板状の遮音壁20が一体に形成されている。【選択図】図1
