GROMMET

The grommet also includes an annular opposing portion that opposes a portion of the vehicle body panel surrounding the insertion hole, and is sandwiched between the vehicle body panel and a bracket fixed to the vehicle body panel. Furthermore, the grommet includes a coupling portion that couples the insertion portion and the opposing portion so as to close a gap between the insertion portion and the opposing portion. The opposing portion includes an annular sealing portion to be in intimate contact with the vehicle body panel. The coupling portion includes a plurality of pleat portions that extend along a circumferential direction of the opposing portion, and are adjacently arranged in a radial direction of the opposing portion, when viewed from an axial direction of the opposing portion.
