PROBLEM TO BE SOLVED: To aim for vibration isolation of a wiring harness.SOLUTION: A grommet 10 for supporting a wiring harness WH on a panel P, by being fixed to the outer periphery of the wiring harness WH to be inserted into the through hole Pa of the panel P, and being held therein, has a large diameter cylindrical part 11 fixed to the through hole of the panel, tapered cylindrical peripheral walls 12, 13 extending in the axial direction from the large diameter cylindrical part, an annular space S formed on the inside of the large diameter cylindrical part and tapered cylindrical peripheral walls, and a bulkhead 20 provided in the annular space S, while coupling the outer peripheral end 20a to the inner periphery of the large diameter cylindrical part 11, and suppressing natural oscillation of the wiring harness WH. Rigidity of the bulkhead 20 is set based on the mass of the panel.SELECTED DRAWING: Figure 1

    【課題】ワイヤハーネスの防振を図る。【解決手段】パネルPの貫通孔Paに挿通されるワイヤハーネスWHの外周に固定され、貫通孔Paに保持されることで、パネルPにワイヤハーネスWHを支持するグロメット10であって、パネルの貫通孔に固定される大径筒部11と、大径筒部から軸方向に延在するテーパ筒状の周壁12、13と、大径筒部とテーパ筒状の周壁との内側に形成された環状空間Sと、この環状空間S内に設けられ、外周端20aが、大径筒部11の内周に連結され、ワイヤハーネスWHの固有振動を抑制する隔壁20と、を有し、隔壁20の剛性が、パネルの質量に基づいて設定されている。【選択図】図1
