To provide a grommet which can protect a locking pawl from excess force for turning a lock pawl end of a mounted member in a direction of the outside of an outer peripheral surface of a grommet inner.SOLUTION: A grommet 10 inserted from one side into the other side of a mounted member 1, comprises a grommet body 11 and a grommet inner 30. The grommet body 11 comprises a large diameter cylinder part 12 which contacts a peripheral part 2a of a through hole 2 of the mounted member on one side in a state of being mounted to the mounted member. The grommet inner 30 comprises: an annular body part 32 which can be attached to the large diameter cylinder part; an inner lock 40 which locks the body part 32 to the peripheral part 2a; and a protective rib 38 which is adjacent to the inner lock 40 in a circumferential direction of an outer peripheral wall 32a of the body part to project in a radial direction. A locking pawl 41 of the inner lock comprises: a locking step part 41a which can be locked to the peripheral part 2a; and a locking pawl end 41c in which an outside surface in the radial direction is inclined to the inside in the radial direction from the locking step part to a rear end 41d in an insertion direction. The rear end 41d of the locking pawl end is located inside in the radial direction than an outside end in the radial direction of the protective rib 38.SELECTED DRAWING: Figure 8
【課題】被取付部材ロック爪端部をグロメットインナの外周面外側方向へ向ける過度な力からロック爪を保護し得るグロメットを提供する。【解決手段】被取付部材1の一方側から他方側に挿入されるグロメット10はグロメット本体11とグロメットインナ30を備える。グロメット本体11は被取付部材に取り付けた状態で一方側で被取付部材の貫通孔2の周縁部2aに接触する大径筒部12を備える。グロメットインナ30は大径筒部に装着可能な環状の本体部32と本体部32を周縁部2aに係止するインナーロック40と本体部外周壁32aの周方向でインナーロック40に隣接し径方向に突出する保護リブ38を備える。インナーロックのロック爪41は周縁部2aに係止可能な係止段部41aと径方向外側面が係止段部から挿入方向後端41dまで径方向内側に傾斜したロック爪端部41cを備える。ロック爪端部の後端41dは保護リブ38の径方向外側端部よりも径方向内側に位置する。【選択図】図8
