• the grommet body comprising:
• a cylinder portion into which the wire harness is inserted;
• a first conical flange portion extending from an outer circumference of the cylinder portion, and formed in a conical shape expanding toward the vehicle body panel,
• an annular seal lip formed in a shape protruding from an outer circumferential edge portion of the first conical flange portion, the outer circumferential edge portion being on a surface opposing the vehicle body panel;
• and
• a second conical flange portion extending from an outer circumferential end of the first conical flange portion, and formed in a conical shape expanding toward the vehicle body panel at a conical angle smaller than a conical angle of the first conical flange portion.
