る。2. Description of the Related Art When a wire harness is passed through a panel hole formed in an automobile panel or the like, a grommet made of a flexible material such as rubber is used to prevent the wire harness from being damaged by interference with the panel hole. Generally, the wire harness is passed through a through hole formed in the grommet by fitting the wire harness into the hole. FIG. 8 is a schematic view of a conventional grommet, and FIG.
FIG. 4 shows a perspective view of a cross section sliced along the A ′ plane. At this time, when waterproofing is required on any side of the panel 1, not only the adhesion and airtightness of the fitting between the grommet 2 and the panel hole 11, but also the wire harness 3 is required.
Hermetic sealing between lines is also required. In such a case,
As shown in FIG. 9, a process for forming the line waterproof body 4 using a resin or the like for the wire harness 3 is required. FIG.
Next, a method for manufacturing a conventional line waterproof body in a grommet will be described. As shown in FIGS. 1A and 1B, in a conventional method for manufacturing a waterproof body between lines, a wire harness 3 in which a plurality of wires are bundled is passed through a grommet 2 and then polyurethane is opened from the opening side of the grommet 2. The two-part curable resin S is poured to realize the inter-line waterproof body 4 of the wire harness 3.

の要因ともなっている。However, in the above-mentioned method, there are some problems since a two-part curable resin is used. A resin having a fast curing time tends to cause clogging of the nozzle of the injection machine, resulting in poor yield. In addition, since it does not sufficiently penetrate between the wires of the wire harness, there is variation in quality. On the other hand, in the case of a resin with a slow curing time, it takes time for the resin to cure between the wires of the wire harness, and the injected resin flows easily, so the wire harness cannot be moved until it cures. There is. Further, also in the manufacturing process, a resin injection process must be provided after the wire harness assembling process, which causes a cost increase.

ができる。FIG. 1 (b) shows a first embodiment of the method for manufacturing a waterproof body according to the present invention. As shown in the drawing, in the present embodiment, the first mold 5
The wire harness 3 is made to penetrate through the water-stopping agent filling space 53 and the opening 54 formed in the first and second molds 52, and while maintaining the wire harness 3 by the opening 54, the wire harness 3 has a predetermined cross-sectional shape (here, circular). Shape it. At this time, if necessary, an elastic material may be added to a portion of the opening 54 that comes into contact with the wire harness 3, so that the hermeticity inside the water-stopping agent filling space 53 may be increased. Then, the water stopping agent P is injected into the water stopping agent filling space 53 via the water stopping agent injection port 56. Here, a thermoplastic polyamide resin is used as the water stopping agent P. Since the resin has a very low viscosity in the molten state, it has good penetration between wire harness lines,
In addition, since the curing time is short, the injection step can be shortened. In this example, the water-stopping agent injection port 56 is provided only at one place. However, by providing the water-stopping agent at a plurality of places, the water-stopping agent can be uniformly injected into the entire wire harness, and a wire having a higher waterproofing ability can be obtained. It is also possible to form a waterproof body. According to the present invention, since a molding method using a mold is employed, the processing accuracy of the waterproof line portion can be improved, and at the same time, the waterproof performance between lines can be improved. Furthermore, unlike the conventional method, the wire harness 3
In addition to the above, it can be performed before the assembling step, and the manufacturing operation of the waterproof liner can be performed more easily, so that the cost for assembling into the manufacturing step can be reduced.

This embodiment is different from the first embodiment in that the wire harness 3 is twisted around the axis of the wire harness 3 between the step of setting the wire harness 3 and the step of injecting the waterproofing agent P. And a step of compressing the wire harness 3 in the axial direction. Specifically, after the wire harness 3 is set on the first mold 51 and the second mold 52 as shown in FIG. 5A, the wire harness 3 is connected to its axis as shown in FIG. Twist around the core (No. 1 in the figure),
Next, as shown in FIG. 5C, the material is compressed in the axial direction (No. 2 in the figure), and finally, the water-stopping agent P is injected.
