The grommet is provided with an electric wire fixing portion 10, a panel fixing portion 20, and a connecting portion 30. The difference from the above-described embodiment is that the fixing portion 10 and the connecting portion 30 are formed in two layers. That is, the internal wire fixing portion 11 is provided inside the wire fixing portion 10 and
Are provided with internal connection portions 31 respectively.

があった。However, in the grommet shown in FIG. 4, there is a problem that the soundproof material 40 is forgotten on site because the soundproof material 40 is a separate component. Further, in the grommet shown in FIG. 5, there is no problem of forgetting to attach the soundproofing material. However, when the wire harness W is passed through the internal wire fixing portion 11, the internal wire fixing portion 11 is expanded. Must also be extended,
There is a problem that it is difficult to expand since there are two expansion locations: the internal wire fixing portion 11 and the wire fixing portion 10 located on the outer periphery thereof. Further, since the grommet shown in FIGS. 4 and 5 has only one fixed portion with the wire harness W, when the wire harness W is pulled in the longitudinal direction,
There is a problem that the wire harness W easily slides in the wire fixing portion 10 or the internal wire fixing portion 11 in the longitudinal direction.

ることができる。When the wire harness is formed as described above, when the wire harness is inserted into the wire fixing portion and the second wire fixing portion, the wire fixing portion and the second wire fixing portion expand, but they are located at different positions. Therefore, the extension work can be easily performed. Further, since the second connecting portion can be used by being positioned inside the connecting portion, a grommet having excellent soundproofing properties can be obtained. Furthermore, since the two portions of the wire fixing portion and the second wire fixing portion are fixed to the wire harness, even if the wire harness is pulled in the longitudinal direction, the wire harness slides in the wire fixing portion and the second wire fixing portion to extend in the longitudinal direction. It becomes difficult to move in the direction, and the movement of the wire harness can be prevented.
