ABSTRACT:
A grommet is provided with a small diameter cylindrical portion defining a first aperture and an expanded diameter portion defining a second aperture which is in communication with the first aperture for inserting a wire harness. In the second aperture of the expanded diameter portion, one end of a bag-shaped portion enclosing the wire harness at a spaced relationship therewith is connected with an end face of the small diameter cylindrical portion. The other end of the bag-shaped portion is made as a tightening portion which sealingly fits with the outer periphery of the wire harness. A gelatinous filler material made of silicone or the like is sealed in the interior of the bag-shaped portion. The small diameter cylindrical portion and the tightening portion are bound with a clamping device against the outer periphery of the wire harness.
