PROBLEM TO BE SOLVED: To reduce as further as possible power required for fitting a grommet into a fitting hole compatibly with enlarging as further as possible holding power in a state where the grommet is fitted into the fitting hole.SOLUTION: A grommet 30 comprises a grommet body 40 formed from an elastic material and an inner member 60. The grommet body 40 includes: a cylindrical part 42 and a large diameter part 50 which is formed to be spread from the cylindrical part 42 to an outer periphery side and with which an annular part 54 that can be disposed at an inner periphery side of a fitting hole 12 is formed in its outer periphery part. The grommet body is fitted from one end side of the large diameter part 50 in an axial direction into the fitting hole 12. The inner member 60 is disposed inside of the annular part 54 and can change a state from an initial state to a diameter enlarged state where a diameter of the annular part 54 is elastically enlarged.SELECTED DRAWING: Figure 3

    【課題】本発明は、グロメットを取付孔に取付ける際に必要な力をなるべく小さくすることと、グロメットを取付孔に取付けた状態での保持力をなるべく大きくすることとを両立できるようにすることを目的とする。【解決手段】グロメット30は、弾性材料により形成されたグロメット本体40と、インナ部材60とを備える。グロメット本体40は、筒部42と、筒部42から外周側に拡がるように形成され、その外周部に取付孔12の内周側に配設可能な環状部54が形成された大径部50とを含み、大径部50の軸方向一端側から取付孔12内に嵌め込まれる。インナ部材60は、環状部54の内側に配設され、初期状態から環状部54を弾性的に拡径させる拡径状態へと状態変更可能とされる。【選択図】図3
