Patent ID: 8544147

Claim:
A grommet comprising: a smaller diameter tubular section having opposite front and rear ends spaced apart along an axial direction diametrically opposed slits extending into the front end; an enlarging diameter tubular section projecting outward and rearward from an intermediate location on said smaller diameter tubular section, the intermediate location is forward of the rear end of the smaller diameter tubular section and rearward of the slits, the enlarging diameter tubular section is provided on an outer periphery of a larger diameter side with a vehicle body latch recess; a pair of semicircular closing plate sections that protrude from inner peripheries of the larger diameter side of said enlarging diameter tubular section in a direction perpendicular to an axial direction, inner ends of the semicircular closing plate sections being formed with semicircular cut-out portions spaced from the smaller diameter tubular section, the semicircular closing plate sections defining bellows with arrays of alternating semicircular projections and semicircular depressions, the semicircular closing plate sections being thinner than the enlarging diameter tubular section; and a pair of half ring sections that protrude rearward from peripheral edges of the semicircular cut-out portions at opposed ends of said pair of semicircular closing plate sections, the half ring sections being spaced from the smaller diameter tubular section at least in an unbiased state of the grommet; wherein after a wire harness passes said smaller diameter tubular section, said enlarging diameter tubular section, and said pair of half ring sections, an adhesive tape is wound around outer peripheries of said pair of half ring sections, and said vehicle body latch recess provided on the outer periphery of said enlarging diameter tubular section is engaged with a vehicle body panel; and wherein said pair of half ring sections are deformed in accordance with an outer diameter of said wire harness secured to said half closing sections by winding of said adhesive tape, and deformation of said semicircular closing plate sections is absorbed by stretch and compression of said bellows before the deformation is propagated to the outer periphery of the enlarging diameter tubular section, so that deformation of said vehicle body latch recess of said enlarging diameter tubular section coupled to an outer periphery side of said semicircular closing plate sections is prevented.
