  • Patent number: 8981228
    Abstract: A grommet is fit externally to a wire harness to be wired in a vehicle and mounted in a through hole of a vehicle-body panel. The grommet has a small-diameter cylindrical portion molded of elastomer and through which the wire harness is tightly inserted. A radial projection in the form of bellows projects radially out from an outer peripheral position of an intermediate longitudinal part of the small-diameter portion. An outer peripheral portion is connected to the outer peripheral end of the radial projection. The outer peripheral portion has a conical tubular shape and is connected at an intermediate longitudinal position to the radial projection. An annular vehicle-body locking recess is provided on the outer peripheral surface of a large-diameter side of the outer peripheral portion. A small-diameter side is thicker than the radial projection portion.

  • Patent number: 8895860
    Abstract: When a grommet provided with a wire insertion tubular portion is mounted in a through-hole of a vehicle body panel by engaging a vehicle body engagement recess on an outer periphery of the grommet with a peripheral edge of the through-hole, the present invention prevents the wire insertion tubular portion from being caught by the peripheral edge of the through-hole, bending toward the vehicle body engagement recess side, and being wedged in between the peripheral edge of the through-hole and the vehicle body engagement recess, and thus enables the grommet to be securely mounted in the through-hole. A rib is provided between an outer peripheral surface on a central axis line side of a wire insertion tubular portion and a peripheral wall of a central tubular portion in order to reinforce a base on the central axis line side of the wire insertion tubular portion.

  • Patent number: 8656553
    Abstract: Waterproof performance of a grommet is stabilized, the grommet being inserted and engaged with a through-hole having a burring in a body panel. A grommet for a wire harness is externally fitted to the wire harness routed in a vehicle and is mounted to a through-hole from which a burring of a body panel projects. The grommet includes a one-piece molded component of one of rubber and elastomer and an annular body engagement recess in an outer peripheral surface of a tubular portion through which the wire harness is inserted. A size between two side surfaces that define a bottom surface of the body engagement portion is set to be less than a projection size of the burring projecting from a periphery of the through-hole. A projecting front end surface of the burring is wedged in and pressed into contact with one of the side surfaces to serve as a seal point.

  • Patent number: 8546695
    Abstract: A grommet includes an inner tube and an outer tube coupled to the inner tube by an annular coupling section. A slant wall section of the outer tube has 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. 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.

  • Patent number: 8487188
    Abstract: A grommet includes a small diameter tubular section and a large diameter tubular section contiguous with the small diameter tubular section. The large diameter tubular section is provided on the outer peripheral surface with a plurality of projecting portions that extend from a connecting part between both of the sections to a side wall of vehicle body engagement annular recess in an axial direction of the large diameter tubular section and are separated from one another in a peripheral direction of the large diameter tubular section. Each of the projecting portions includes an increasing diameter directing slant portion that extends from the proximal end point through the contact point to the bending point in parallel to the outer peripheral surface of the large diameter tubular section, and a decreasing diameter directing slant portion that extends from the bending point to the distal end point and inclines in a reversed slant direction.
