A grommet through which a long member is passed and mounted on a fixing hole of a fixing plate, includes an outer member and an inner member. The outer member includes a cylindrical insertion portion, through which the long member is passed, a brim-shaped close contact portion, extending outward from the insertion portion and having a mounting groove engaging with an edge of the fixing hole and an inner groove, formed on an inside face of the close contact portion. The inner member include a periphery edge portion, substantially shaped into a disc shape having a central opening, and inserted in the inner groove and a projection, extended from the periphery edge portion.
1. A grommet through which a long member is passed and mounted on a fixing hole of a fixing plate, comprising;
an outer member, including:
a cylindrical insertion portion, through which the long member is passed;
a brim-shaped close contact portion, extending outward from the insertion portion and having a mounting groove which is mounted on an edge of the fixing hole; and
an inner groove, formed on an inside face of the close contact portion; and
an inner member, including:
a periphery edge portion, substantially shaped into a disc shape having a central opening, and contained in the inner groove; and
a projection, extended from the periphery edge portion, wherein the projection is contained in the inner groove.
2. The grommet as set forth in claim 1 , wherein the periphery edge portion is shaped into an elliptical disc shape in a plan view; and
wherein the projection projects in a crossing direction with respect to a minor axis of the periphery edge portion.
3. The grommet as set forth in claim 1 , wherein the periphery edge portion is shaped into an elliptical disc shape in a plan view; and
wherein the projection projects in a crossing direction with respect to a major axis of the periphery edge portion.
4. The grommet as set forth in claim 1 , wherein the projection is a plurality of projections extended from the periphery edge portion of the inner member.
5. The grommet as set forth in claim 1 , wherein the inner member includes a guide portion provided with the periphery edge portion extended to outwardly therefrom, and the guide portion having a through hole to path through the long member,
wherein the guide portion is provided with a cut portion so as to accommodate a part of the long member.
6. A combination, comprising:
the grommet of claim 1 , and
the fixing plate comprising the fixing hole.
7. The grommet as set forth in claim 1 , wherein said inner groove extends around substantially an entire periphery of the close contact portion.
