<p>PROBLEM TO BE SOLVED: To enhance the insertion property of a cup part against the hole part of a panel. SOLUTION: The grommet includes both a cylindrical part 9 inserted through a wire harness 26, and a sealing wall 3 intersecting the cylindrical part, is provided with a cup part 2 to be fitted in the hole part 14 of a panel 13, and the sealing wall 3 is flexible in the diameter contraction direction, so that the cup part 2 is contracted in diameter by means of the flexible sealing wall 3. The sealing wall 3 is curved so as to be formed into a S-shape in cross section, and the inner circumferential surface side of a shoulder part 4 for the cup part 2 continued to the sealing wall 3, is formed into a lightening shape 5. In addition, a groove part 8 extended to the grommet axial direction is formed in the thick skirt part 7 of the cup part 2, and the groove part is formed into a V-shape in cross section.</p> |
