A grommet is provided with a small diameter tube portion which receives a wire harness therein in a fitted condition, and is provided with an enlarged diameter tube portion which continues in a generally conical tube shape from one end of the small diameter tube portion. A recessed portion for hooking on an automobile body panel is provided on an outer peripheral surface of the enlarged diameter tube portion. The height of first and second peripheral side walls on opposite sides of the bottom surface of the recessed portion is established so that the height of the second side wall of the small diameter tube portion side in the opposite side is about 50% to 35% of the height of the first side wall of the opening end side of the enlarged diameter tube portion side. Furthermore, the width dimension of the recessed portion between the first side wall and second side wall is greater than the height dimension of the second side wall, and the second side wall deforms inwardly into the recessed portion. Thus, the grommet can be easily installed in a single push-in motion of the grommet into the penetration hole of the automobile body panel.
