Abstract: 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 having a smaller diameter and passing electrical cables in a wire harness in a close contact manner; an annular coupling section protruding from an outer peripheral surface of an intermediate part between both ends of the inner tube at a pushing-in side and a drawing-out side in a longitudinal direction; and an outer tube having a larger diameter, contiguous with an outer peripheral surface of the annular coupling section, and coaxially disposed around the inner tube through a space. The outer tube is provided with a slant wall section that reduces a diameter from a larger thickness portion at a coupling position with the annular coupling section to the drawing-out side. The outer tube is provided with a vehicle body latch recess between the larger thickness portion and the slant wall section in an annular manner.
