Patent number: 6211464Abstract: 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.Type: GrantFiled: May 20, 1999Date of Patent: April 3, 2001Assignee: Yazaki CorporationInventors: Yasunari Mochizuki, Nobutaka Kaneko, Hiroki Goto, Hiroaki Arai
