<p>PROBLEM TO BE SOLVED: To extend a sealing material completely even if a wire harness having a large diameter is inserted. SOLUTION: This water stop grommet has a large-diameter tube 2 and a small-diameter tube 3 in which a wire harness is inserted, and is formed so that a fitting part for a panel inserting hole may be formed on the outer- periphery of the large-diameter tube. An inner tube 5 extending from the small- diameter tube toward opening end of the large-diameter tube, and communication with the small-diameter tube may be formed on the inner part of the large- diameter part. The inside of the inner tube may be a space permitting the liquid hardening sealing material to be filled with the wire harness inserted, and an index rib 17 which is an index of a required charging level of the sealing material may be protrudingly formed on inside of the inner tube. The index ribs are disposed in the circumferential direction of the inner tube at appropriate intervals, thus it is possible to ensure a groove 1 between the index ribs.</p> |
