PROBLEM TO BE SOLVED: To reduce insertion force into a through-hole of a car body panel, in one-motion grommet. SOLUTION: A double-tube shape is provided with an outer tube, by folding back from the front end of an inner tube; the front end as a folded part is formed in large thickness as an insertion part to a through hole; additionally this insertion part is sloped so as to be radially widened in the rearward direction, a front sidewall of a car body lock recessed part provided in the outer tube is formed; and an annular depth of cut part is provided in this insertion part, to constitute internal/external peripheral parts of the insertion part connected through a thin hinge part; the thin hinge part is deformed, when it is pressed into the through hole from the insertion part to extend the internal/ external peripheral parts of the insertion part, to constitute the car body lock recessed part locked to the through-hole, by making the front side wall of the car body lock recessed part pass the through-hole. |
