Even if a wire harness that passes a grommet is bent sharply, a vehicle body latch recess of the grommet is not deformed, thereby enhancing a sealing function. A grommet includes an inner tube through which electrical cables in a wire harness pass in a close contact manner, and an outer tube coupled through an annular coupling section to the inner tube and provided with a slant wall section. The slant wall section of the outer tube is provided with a curved portion at a position having an outer diameter equal to an inner diameter of a through-hole in a vehicle body panel. The curved portion has a different inclination angle from the slant wall section. An inclination angle of the slant wall section at a larger diameter side with respect to the curved portion is set to be smaller than an inclination angle at a smaller diameter side with respect to the curved portion. A larger thickness portion is contiguous with a larger diameter end of the slant wall in parallel to an axial direction. A vehicle body latch recess is provided in an outer peripheral surface of the slant wall section between the larger diameter end of the slant wall and the larger thickness portion in an annular manner. The slant section is provided with a plurality of stepped projecting ribs that extend from a smaller diameter end of the slant wall section to the larger diameter end and are spaced apart from one another in a peripheral direction. The slant wall section is provided on an inner peripheral surface at the smaller diameter side with a bending stress absorbing portion of which an inner surface is recessed annularly to be a smaller thickness.
