り、作業工数の削減も困難であった。Traditionally, grommets are made of a flexible material such as rubber, and have a shape that allows them to fit tightly around a through hole in a panel or the like. Such a grommet has a shape as shown in FIG. 4, for example, but if a connector is attached to the tip of the conductive wire, such as when attaching it to a wire harness or the like, or if multiple conductive wires are not bundled, It was necessary to use a grommet switch to pass the conductive wire through, which had the disadvantage of poor workability. Moreover, even if the grommet b is attached to the conductive wire a, it is necessary to further wrap an adhesive tape d or the like around the penetrating neck C in order to obtain a waterproof structure, making it difficult to reduce the number of work steps.

を一体として被覆して構成することとしたものである。In order to achieve the above-mentioned object for "shi", the present invention provides an alternative to forming a grommet with an engaging claw on the outside of a cylindrical part to be fitted into a panel hole from a flexible material such as rubber. First, a member is formed of a hard elastic material in a shape divided into two by a plane passing through the shaft, and the wire harness is inserted into the shaft hole position and assembled, and then the outer surface of the assembled part is integrally covered with a soft elastic material. This is what we decided to configure.

成し、これを折り曲げて一体に組み立ててもよい。Further, a grommet member made of such a hard elastic material is formed, for example, by injection molding, etc., into a shape in which a completed grommet is divided into two along a plane passing through the axis. Preferably, the molded member is provided with locking parts, such as engaging claws and retaining holes, at corresponding positions for integral assembly, or two.
It is also possible to form a shape in which separate members are connected by a flexible hinge, and then to assemble them together by folding them.

When coating these materials, for example, in the case of vinyl chloride resin, the member is immersed in a plastisol-like composition, or in the case of silicone rubber, it is immersed in a liquid unvulcanized compound, etc., and coated as appropriate. By performing curing treatment at appropriate temperatures and times, it is possible to obtain coatings that meet each purpose. Note that these coating compositions may contain a solvent and the like.

That is, the wire harness 1 is inserted into the through hole 2a of the grommet member 2, and the wire harness 1 is connected by a lock 2h provided at the edge of the abutting surface of the member (FIG. 3(a)→(b)). Then, the grommet part is immersed in the dipping tank 5 filled with vinyl chloride resin plastisol, and the plastisol is permeated not only into the surface of the grommet part but also into the gap between the wire harness 1 and the grommet member 2 (Fig. 3 (C)). ). The grommet portion with plastisol attached to its surface is heat-treated at a temperature of about 130°C to harden it and produce a soft coating.
After passing the connector provided at the end of the wire harness 1 through the hole, if the cylindrical part 2C is inserted, the engaging claw 2d will engage with the edge of the panel hole and be fixed, but the panel 4
There is a soft elastic coating layer between the front surface of the grommet 2 and the lower surface of the grommet 2, which together with the action of the annular groove 2b on the lower surface of the grommet 2 forms a good waterproof structure.
