PROBLEM TO BE SOLVED: To restrain insertion force of a grommet which is pushed into a through-hole in a vehicle body panel. SOLUTION: This grommet includes a small-diameter cylindrical section and an enlarged-diameter cylindrical section, continuous with the small-diameter cylindrical section. A plurality of protrusions, extending in the axial direction from small-diameter cylindrical section end side to inclined wall front end are protruded at the outer-periphery surface of the enlarged-diameter cylindrical section. The small-diameter cylindrical section end part of each of the protrusions is protruded in step-wise manner, from the enlarged-diameter cylindrical section outer-periphery. The plurality of protrusions, extending in the axial direction at regular intervals in the peripheral direction, are provided along the outer periphery of the enlarged-diameter cylindrical section formed with recessed cuts, provided at an end surface facing the small-diameter cylindrical section side. |
