PROBLEM TO BE SOLVED: To provide an inexpensive grommet which can easily connect a grommet body and a resin inner member, and stably secure the sealability in an irregular engaging part of the grommet body and the inner member even in a horizontal deviation state where the grommet body and the inner member are deviated in a circumferential direction from a regular connecting position.SOLUTION: A grommet is configured by the combination of an elastic grommet body 14 in a cylindrical shape and a resin inner member 12. The inner member 12 has a protrusion 25 which protrudes so as to penetrate through an outer peripheral cover 44 of the grommet body 14. The grommet body 14 at least has a swollen part 47 with a fitting hole which swells to the same direction as the protrusion 25 from the outer peripheral cover 44 of the grommet body 14 so as to airtightly fit to the protrusion 25 at a tip end side of the protrusion 25, and the height h of the swollen part in a protruding direction of the protrusion from a peripheral wall surface 23a of the inner member 12 is larger than an external diameter D of the swollen part in a direction orthogonal to the protruding direction.SELECTED DRAWING: Figure 4 |
