METHOD OF MANUFACTURING WATER-STOP STRUCTURE FOR GROMMET, AND, WATER-STOP STRUCTURE FOR GROMMET

摘要

PROBLEM TO BE SOLVED: To provide a technology for accomplishing easily with a little work burden a water-stop structure for a grommet having a secure water-stop performance.;SOLUTION: A filling sealed body 20 is obtained by sealing in a sealing member 21 filling 2 which has fluidity in a sealed state and has such a character as to be hardened by touching air. The filling sealed body 20 is disposed in a wire group 90 of a wire harness 900, and a diameter-enlarged grommet 1 is externally fitted to the wire harness 900. Continuously, the diameter enlargement of the grommet 1 is canceled and the grommet 1 is diameter-reduced to the original state. The wire group 90 is then pressurized by an inner wall of the grommet 1, and the filling sealed body 20 disposed therein is broken. As a result, the filling 2 sealed in the filling sealed body 20 is permeated in the wire group 90.;COPYRIGHT: (C)2012,JPO&INPIT
