Grommet

摘要

To provide a grommet that can be smoothly inserted into a through-hole in a vehicle body panel so that a vehicle body latch recess provided in the grommet can receive an peripheral edge around the through-hole without catching the recess by the through-hole. The grommet includes: an inner tube for passing electrical cables in the wire harness in a close contact manner; and an outer tube coupled through an annular coupling section to an outer peripheral surface of the inner tube and provided with a slant wall section. The outer tube is provided on a larger diameter end of the slant wall section with a larger thickness portion in parallel to an axial direction. An annular vehicle body latch recess is provided in an outer peripheral surface at a boundary area between the larger diameter end of the slant wall section and the larger thickness portion. The slant wall section is provided on an outer peripheral surface with a plurality of stepped projecting ribs that extend radially from a smaller diameter end of the slant wall section to the larger diameter end and are separated apart from one another in a peripheral direction. A distal end of each of the projecting ribs is disposed at a side surface end of the vehicle body latch recess. Each of the projecting ribs is provided on a stepped top surface with a first slant surface that is inclined down to the side surface end of the vehicle body latch recess, and is provided on both side surfaces with a second slant surface and a third slant surface that are inclined down from the top surface across the first slant surface. The first, second, and third slant surfaces form a three-side-cut-away portion.
