Grommet

摘要

A grommet for a wire harness is provided that includes a small-diameter portion into which a wire harness is insertable and which is tightly contactable with the wire harness, a large-diameter portion having an engaging groove engageable with an inner peripheral edge of an automobile body panel, an extending portion extending past an end of the small-diameter portion along an axial direction thereof, and a lip portion radially projecting from an outer peripheral surface of the extending portion. The lip portion tightly contacts an inner peripheral surface of the insertion hole from inside when the grommet is mounted. The lip portion has a step portion including a first face and a second face respectively engageable with the inner peripheral surface and an outer surface adjacent to a peripheral edge of the insertion hole. Thus, the tightness of the seal between the grommet and a sound insulator secured on the automobile body panel is improved.
