PROBLEM TO BE SOLVED: To prevent break of inserted wire, by preventing bending stress from concentrating at both ends of a bellows tubular section. SOLUTION: This grommet 10 includes a large-diameter cylindrical section 13, which accommodates a resin inner 14 with a locking section (vehicle body locking claw) 14a to be latched to a through-hole in a door panel, a large- diameter cylindrical section 12 which accommodates a similar resin in the inside inner to be latched, to a through-hole of a body panel, and a bellows tubular section 11 provided between the large-diameter cylindrical sections 13 and 14. The grommet 10 is positioned between the body panel and the door panel to wind, and is capable of expanding or contracting, when the door panel opens or closes. At the bellows tubular section 11, ribs 16 in the axial direction are extended astride over a plurality of roots 11a and crests 11b. The ribs 16 become thick at the roots 11a, with the roots 11a being embedded in it. |
