GROMMET
First Claim
1. A grommet comprising:
- a tubular grommet inner member to be inserted into an insertion hole formed in an attachment panel, the grommet inner member comprising a plurality of lock portions which are provided on an outer surface of the grommet inner member and configured to render the grommet inner member retainable at an inner edge of the attachment panel around the insertion hole from a first surface of the attachment panel; and
a tubular grommet outer member attached coaxially to an end of the grommet inner member from a second surface of the attachment panel, the grommet outer member being configured to abut on the attachment panel to provide sealing between the grommet inner member and the attachment panel,wherein the grommet inner member further comprises at least one of a centering unit and a temporary anchor unit provided on the outer surface of the grommet inner member,the centering unit comprising a plurality of centering portions configured to elastically abut on the attachment panel at the inner edge thereof around the insertion hole so as to position the grommet inner member in a center of the insertion hole when the grommet inner member is inserted into the insertion hole,the temporary anchor unit comprising a plurality of engaging portions configured to engage with the inner edge of the attachment panel around the insertion hole, thereby supporting the grommet inner member in an axial direction thereof before the lock portions make the grommet inner member retained at the inner edge of the attachment panel around the insertion hole when the grommet inner member is inserted into the insertion hole.

Abstract
In a grommet (1), a centering unit and a temporary anchor unit are provided on an outer surface of a grommet inner member (2). The centering unit includes a plurality of centering portions (e.g., centering claws 8) configured to elastically abut on an attachment panel (20) at an inner edge thereof around an insertion hole (21) so as to position the grommet inner member (2) in a center of the insertion hole (21). The temporary anchor unit includes a plurality of engaging portions (e.g., temporary anchor claws 7) configured to engage with the inner edge of the attachment panel (20), thereby supporting the grommet (1) in an axial direction thereof before lock portions (e.g., lock claws 6) make the grommet inner member (2) retained at the inner edge of the attachment panel (20) around the insertion hole (21) when the grommet inner member (2) is inserted into the insertion hole (21).
