PROBLEM TO BE SOLVED: To provide a grommet which has satisfactory sealability without using a filler.SOLUTION: In a grommet 16, a cylindrical part 17 and a flange part 18 are integrally formed by using an elastic material such as a silicon rubber, and the cylindrical part has a cylindrical shape of a circular cylinder or the like and has a bellows shape inside of the flange part. In the cylindrical part, a hollow 21 is provided which can be expanded radially inside by pressurization, and formed so as to perform pressurization and evacuation by injecting a gas or a liquid via an injection port. The flange part is provided in the vicinity of at least one end 24 of the cylindrical part in an axial direction and on an axially outer surface S, a groove is provided that extends in a circumferential direction of the cylindrical part.SELECTED DRAWING: Figure 3
【課題】充填材を用いること無く良好な密封性を有するグロメットを提供する。【解決手段】グロメット16は、シリコンゴムなどの弾性材料を用い、筒部17とフランジ部18が一体的に形成され、筒部は円筒等の筒状でフランジ部より内側に蛇腹形状を有し、筒部には加圧により径方向の内側に膨らみ得る中空21を設け、注入口を介して気体または液体を注入して加圧及び減圧が可能に形成されている。フランジ部は筒部の軸方向における少なくとも一方の端24近傍に設けられ、軸方向の外側の面Sに筒部の周方向に沿って延びる溝を設けた。【選択図】図3
