First, the heat-shrinkable tube 2 is put on the wire harness W / H. Next, a plurality of sealing members 1 are attached to a large number of electric wire groups by passing the electric wire w of the wire harness into the parallel grooves 1a of the sealing member 1 formed of a substantially comb-shaped block shown in FIG. As shown in (c), the plurality of sealing materials 1 are staggered at the waterproof position of the electric wire group. Then
As shown in FIG. 8D, the heat-shrinkable tube 2 is moved to cover the sealing material 1, and then heated to shrink the heat-shrinkable tube 2 so as to adhere to the wire group. Next, as shown in FIG. 8E, the sealing material 1 is applied in an AC magnetic field by applying a high frequency.
The magnetic material is induction-heated, and the heat is generated to dissolve the base material, thereby penetrating the sealing material between the electric wires. Then, FIG.

As shown in FIG. 2B, when the sealing member 1 is shifted and put on the sealing member 1, the heat-shrinkable tube 2 is caught on the sealing member 1, and the sealing member 1 is easily shifted laterally. If the position of the sealing material 1 shifts, the position where the sealing material 1 melts and penetrates between the electric wires to be waterproof is shifted from a required position for attaching the grommet, and water leakage occurs when mounted on an automobile. There is. Therefore, it is necessary for an operator to visually confirm whether the position of the sealing material is not deviated from a predetermined waterproof position, which requires a lot of labor and makes it difficult to perform accurate positioning by visual confirmation. Note that the same phenomenon occurs even when the sealing materials 1 are not staggered.
