A grommet 10 comprises a smaller diameter tubular section 11, an enlarging diameter tubular section 13, and a larger diameter tubular section 14. The smaller diameter tubular section 11 is connected through the enlarging diameter tubular section 13 to the larger diameter tubular section 14 in an axial direction. A U-shape folded portion 20 is provided on a connecting portion (a middle diameter tubular section 12) between the smaller diameter tubular section 11 and the enlarging diameter tubular section 13. A flap section 19 that spreads conically toward the enlarging diameter tubular section 13 is provided on an outer periphery of the smaller diameter tubular section 11 or an outer periphery of the folded portion 20. The folded portion 20 is stretched straightly when the grommet 10 is inserted into a through-hole 41. When a vehicle body latching recess 18 is engaged with a peripheral edge around the through-hole 41, the folded portion 20 returns to the original shape, and a distal end peripheral edge 19a of the flap section 19 contacts with a vehicle body panel 40 at a passenger room side Y to define a sound absorbing closed space S. |
