Abstract
The present invention is directed to a grommet that engages around an outer periphery of a wire harness and is inserted into a through hole of the automobile body. The grommet is provided with a generally cylindrical portion that tightly engages a wire of the wire harness and a generally conical portion extending from one end of the cylindrical portion. A thickened portion is provided around the conical portion in an enlarged end. A recess configured to be engaged with the automobile body is provided on an outer peripheral surface of the thickened portion. One side wall of the recess in the enlarged end extends outwardly and has a lip projecting from a tip of the extended side wall. A bottom surface of the recess has either a curved portion or an inclined portion so that an edge of the through hole of the automobile body panel is forcefully pressed into and distorts the curved or inclined portion. Another side wall, which faces toward the lip-side side wall (extending side wall), is configured to approach the lip-side side wall along a direction from the bottom surface to an opening end of the recess. The automobile body panel, which is engaged with the inner surface of the recess, contacts the grommet at the curved portion or the inclined portion of the recess, as well as the side wall and the lip. Thus, plural sealing points are provided between the grommet and an automobile body panel, thus, waterproofness is improved.
