<p>A grommet includes a small tubular section, an enlarging tubular section continued from an end of the smaller tubular section, and an annular recess on an outer surface at a large diameter end of the enlarging tubular section. The small tubular section is inserted into a through-hole from one side of a vehicle body panel so that the annular recess engages the vehicle body panel. Stepped projections extend axially from the small tubular section to the annular recess . Each stepped projection has an angle rib that protrudes from a connecting end of the small tubular section to a position where the angle rib contacts a peripheral edge around the through-hole. Slopes of the angle ribs at upper positions contact a peripheral edge around the through-hole at a position where the slopes at the upper positions do not pass the annular recess.</p> |
