Claims

[Scope of utility model registration request]

Made of elastic material with a fitting part that fits into the oval mounting hole, a flange located above and below the fitting part on the outer periphery to prevent removal, and a through hole formed inside to insert the lead wire. In the grommet, an annular projection having a smaller diameter than the lead wire is formed in the through hole at a position corresponding to the fitting part, and
The grommet is characterized in that the outer shape of the fitting portion is approximately elliptical with a short axis having a slightly larger diameter than the mounting hole.
