In order to insert a wiring harness and to retain it in a mounting hole in a body panel a grommet is so designed that a first cylinder and a second cylinder are connected together via a connector and that a plurality of flanges and guide portions are radially formed. For the grommet when the second cylinder is everted, the flanges are closely attached to the outer face of the first cylinder and are inserted into the mounting hole and do not interfere with the guide portions Then, when reversion of the second cylinder is effected, a groove is fitted into the mounting hole.

Grommet

A grommet is provided for positively mounting a long member (e.g. a wire harness) in such a manner that the long member is passed through a mounting plate such as a panel of a vehicle body. A grommet for passing and holding a wire harness relative a mounting hole formed through a mounting plate includes a first cylindrical portion for passing the wire harness therethrough, a second cylindrical portion connected to the first cylindrical portion through a connection portion, a groove formed in an outer peripheral surface of the second cylindrical portion, and a flange portion formed on that portion of the outer peripheral surface of the second cylindrical portion lying between the groove and the connection portion. A plurality of guide portions, extending radially from the outer peripheral surface of the first cylindrical portion, are brought into contact with an inner peripheral edge of the mounting hole in such a manner that the second cylindrical portion is disposed coaxially with the mounting hole.

Grommet having a resilient flange

A grommet is provided for positively and easily mounting a longitudinally shaped member (e.g. a wire harness) in such a manner that the member is passed through a mounting plate such as a panel of a vehicle body. The grommet includes a second cylindrical portion connected through a connection portion to a first cylindrical portion for passing a wire harness therethrough. A groove, formed in an outer peripheral surface of the second cylindrical portion, and flange portions, formed between the groove and the connection portion, maintain the angle of projection of the flange portions with respect to the second cylindrical portion. The second cylindrical portion is turned inside out, so that the flange portions, deformed into a generally tapering, cylindrical shape, are passed through a mounting hole, and then the second cylindrical portion is restored into its initial shape, so that the grommet is located on the panel in a predetermined position.
