  • Patent number: 8375513
    Abstract: A grommet includes an inner tube, an outer tube coupled through an annular coupling section to 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 and an annular latch recess between the larger diameter end of the slant wall section and the larger thickness portion. The slant wall section has a plurality of stepped projecting ribs that extend radially from a smaller diameter end of the slant wall section to the larger diameter end. 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 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.

  • Patent number: 8203079
    Abstract: A grommet that sheathes a wire harness for a motor vehicle comprising a smaller diameter tubular section provided at one end of the grommet and capable of being inserted into a through-hole in the motor vehicle, a tapered tubular section including a slant wall extending from the smaller diameter tubular section and the slant wall includes a pair of opposed longer sides, a pair of opposed shorter sides, and corner slant sides provided between the longer sides and the shorter sides, and a larger diameter tubular section extending through a vehicle body locking recess to a larger end part of the tapered tubular section and the larger diameter tubular section includes a pair of opposed longer sides, a pair of opposed shorter sides, and four round corners, the tapered tubular section is capable of deformation inward such that the vehicle body locking recess is engaged with the through-hole.

  • Publication number: 20110079417
    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 for passing electrical cables in said wire harness in a close contact manner; and an outer tube contiguous with an outer peripheral surface of said inner tube and provided with a slant wall section. The slant wall section of the outer tube is provided with a curved portion at an outer diametrical position having an outer diameter corresponding to an inner diameter of the through-hole. The curved portion has a different inclination angle from the slant wall section. An inclination angle of an outer peripheral surface 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.

  • Publication number: 20110073351
    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 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.

  • Publication number: 20110073350
    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.

  • Publication number: 20110067201
    Abstract: 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 a 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.

  • Publication number: 20110061897
    Abstract: To provide a grommet of which a vehicle body latch recess is not deformed, thereby maintaining a good sealing function, even if a wire harness that passes the grommet is bent sharply. The grommet includes: an inner tube for passing electrical cables in the wire harness in a close contact manner; an annular coupling section protruding from an outer peripheral surface of the inner tube; and an outer tube contiguous with an outer peripheral surface of the annular coupling section and disposed coaxially with the inner tube. The outer tube is adapted to couple the annular coupling section to a larger thickness portion of the outer tube and to couple a reducing diameter slant wall section to the larger thickness portion. The outer tube is provided on an outer peripheral surface at a boundary area between the larger thickness portion and the slant wall section with a vehicle body latch recess in an annular manner. The annular coupling section is formed into a smaller thickness.
