A grommet includes a first cylindrical portion for passing a wire harness therethrough, a second cylindrical portion for fitting in a mounting hole in a panel , and a connecting portion interconnecting the first and second cylindrical portions and . The second cylindrical portion is turned inside out, and flange portions , formed on the second cylindrical portion , are passed through the mounting hole . Subsequently, the second cylindrical portion is restored into its initial shape by its own restoring force, thereby mounting the grommet in a predetermined position. Ribs are formed on an inner peripheral surface of the connecting portion , and the position of folding of the connecting portion is determined by these ribs, thereby preventing the grommet from being excessively reversed, and by doing so, the restoration of the grommet into its initial shape can be easily started.

Grommet

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.
