<p>PROBLEM TO BE SOLVED: To improve water-tight performance in an inserting hole to which a small number of wires are inserted in such a case where a small number of wires are inserted into the insertion hole provided to a cylindrical part of a grommet having an enlarged diameter. SOLUTION: The grommet 10 includes a cylindrical part 11 having a small diameter which is formed of a rubber material or elastomer to insert a group of many wires W1 in the closely stuck condition, and the cylindrical part 12 which is connected to one end of the cylindrical part 11 having the small diameter and includes a recess 15 for engagement with a body at the external circumferential surface in the end aperture side. The inserting hole 13 is provided in continuation with a guide cylinder 14 projected at the external circumferential surface of the circumferential wall of the cylindrical part having the enlarged diameter, a small number of wires W2, one or two wires, are inserted into the insertion hole 13 provided at the circumferential wall of the cylindrical part 12 having enlarged diameter, an elastic resin tape 20 is used to wind previously a small number of wires W2 at the time of insertion thereof, thereafter these wires are inserted into the guide cylinder 14 and insertion hole 13, and the external circumferential surface of the guide cylinder 14 is tightened with a tie-band 21 under this condition.</p> |
