Abstract
A grommet is mounted into an opening formed in a mating member after a wire harness containing a plurality of wires tied up in a bundle is inserted through the grommet. The grommet has a base portion formed of rubber or resin and has in the annular outer peripheral wall thereof a mounting groove fittable with an opening edge of the mating member, a roof portion extending inwardly from the opening end of the base portion, a medium diameter portion formed in a cylindrical shape having an inside diameter larger than the diameter of the wire harness to be inserted therethrough and extending upwardly in the axial direction of the grommet from the roof portion, and a small diameter portion reducing continuously in diameter from the opening end of the medium diameter portion and extending further upwardly in the axial direction of the grommet in a cylindrical manner. In the grommet, there is further formed an annular cavity in the portion of the inner peripheral wall of the base portion that corresponds to the position of the mounting groove.
