<p>PROBLEM TO BE SOLVED: To improve the mounting performance and noise insulating performance of a grommet. SOLUTION: This grommet 10 is equipped with an expanding-bore tube part 12 and a large-bore tube part 13, in continuity with a small-bore tube part 11 allowing a wire harness to tightly pass therethrough, equipped with a fold back part 14 folded back from a joining point of the expanding-bore tube part 12 to the large-bore tube part 13 and, in continuity therewith, a thick- walled large-bore part 15, equipped with a lock piece 16 and a panel fit groove 17, and further equipped with a noise insulating wall 18 projecting from the large-bore tube part 13. The grommet 10 is molded with the fold back part 14, etc., turned inside out at the time of molding. When the grommet 10 is mounted on a vehicle body panel P, it is put through a panel through hole Pa with the large-bore tube part 13 in the lead, thus the thick-walled large-bore part 15, etc., are turned over in order by making contact with the vehicle body panel P, etc., and fitted to the vehicle body panel P, and the noise insulating wall 18 makes pressing contact with an inner circumferential surface 15d of the thick-walled large-bore part 15 in the mounted state of the grommet 10.</p> |
