Claims

[Scope of Claim for Utility Model Registration] (1) Forming a concave groove and a convex plate portion that fit into each other at the inner circumferential edge of the notch for inserting electric wires in the case, etc. and the outer circumferential edge of the mounting bulge of the grommet; A tapered inner surface whose thickness gradually increases from the fitting end along the extension direction of the groove is formed inside the groove, and a tapered inner surface gradually increases in thickness from the fitting end on the outer surface of the convex plate portion in correspondence with the tapered inner surface. A grommet seal structure characterized by forming a tapered outer surface with increasing thickness. (2) A concave groove and a convex plate portion that fit into each other are formed on the inner circumferential edge of the notch for inserting electric wires in the case, etc. and the outer circumferential edge of the mounting bulge of the grommet, and a fitting end is formed inside the concave groove. The convex plate portion forms a tapered inner surface whose thickness gradually increases along the extending direction of the groove, and a wedge whose thickness gradually increases from the fitting end corresponding to the tapered inner surface within the groove. A grommet seal structure characterized by fitting between.
