GROMMET
Document Type and Number:
WIPO Patent Application WO/2010/073856
Kind Code:
A1
Abstract:
A grommet mounted in a through-hole in a vehicle body panel and through which a wire harness is passed. Even if taping only one side, the grommet shape is retained and the grommet is prevented from deforming in the direction in which an engaging recess of the grommet separates from the peripheral edge of the through-hole. The grommet comprises: an enlarged-diameter tube which connects to the outer periphery of the longitudinal intermediate section of a small-diameter tube through which wires are tightly passed, and which is enlarged in diameter to surround the other side of the small-diameter tube; an engaging recess which is annularly formed in the outer peripheral surface of the enlarged-diameter tube on the large diameter side thereof; inner ribs provided at intervals in the circumferential direction and connecting between the inner periphery of the enlarged-diameter tube and the outer peripheral surface of the other side of the small-diameter tube; and wire insertion tubes which connect to through-holes for wires formed in the enlarged-diameter tube and which extend through the inside of the enlarged-diameter tube and project from the opening end on the large-diameter side. The inner ribs stick out with a clearance from the inner peripheral surface of the enlarged-diameter tube from the position where the enlarged-diameter tube contacts the inner peripheral surface of the through-hole of the vehicle body panel to a position facing the engaging recess.
