The present invention improves sealing performance for a grommet mounted on a metal pipe and attached to a through-hole in a vehicle body panel, the metal pipe sheathing an exterior of a wire harness. The grommet includes a small diameter cylinder tightly attached to the metal pipe inserted therethrough, and an enlarged diameter portion tightly attached to and held on the vehicle body panel on a periphery of the through-hole. A metal bracket is fixated to the enlarged diameter portion, the metal bracket covering an exterior surface side of the enlarged diameter portion and including fixers bolted to the vehicle body panel. An exterior circumferential surface of the small diameter cylinder includes annular recesses and protrusions alternating in a length direction, while an interior circumferential surface includes a plurality of annular seal lips in the length direction. A clamp is fitted around an exterior of the small diameter cylinder.
