Title:
GROMMET
Document Type and Number:
WIPO Patent Application WO/2008/044345
Kind Code:
A1
Abstract:
A grommet that is an elastic body and is fitted over an electric wire group laid
between a vehicle-body panel and a movable body that is a door or a trunk lid hinged
to the vehicle-body panel. The grommet has a large diameter section having, at
both ends in the longitudinal direction, annular engagement grooves inserted
and engaged with through-holes individually formed in the vehicle-body panel
and the movable body, small diameter sections contiguous to the large diameter
section, and a bellows tube section contiguously provided between the small
diameter sections on both sides. The bellows tube section is bent in a U-shape
when the movable body is closed and has large diameter crests and small diameter
roots that are alternately continuously arranged at equal intervals across
the overall length of the bellows tube section. That specific region of the bellows
tube section that holds the top of the bend when the bellows tube section is bent
in U-shape has a greater wall thickness than the remaining regions to make the
curvature radius of the bend greater.
