PROBLEM TO BE SOLVED: To provide an attachment structure of a grommet, which has the satisfactory attachment performance, the high water-proofness, and the high dust-proofness. SOLUTION: In this attachment structure of a grommet 1, comprising a grommet outer 5 and a grommet inner 4 having a higher rigidity than the grommet outer, the grommet inner 4 is coupled with the end of the grommet outer 5 to be unified with it. A protrusion protruding forward from the end of the grommet outer 5 is formed on the grommet inner 4 and a protrusion 8, which protrudes radially outward from the inner circumferential edge of a through-hole 3 formed in an attachment member 2 to which the grommet 1 is attached and, further, retreats radially inward elastically, is formed on the protrusion of the grommet inner 4. The circumferential edge of the through-hole 3 is held between the protrusion 8 and the end of the grommet outer 5 to connect the grommet 1 with the attachment member 2. |
