い。 As one such prior art, for example, there is a technology disclosed in Japanese Utility Model Publication No. 57-31466.
This is because, as shown in FIG. 5, the wire convergence part 11 constituting the narrow cylindrical part is divided into two convergence pieces 16a and 16b by slits 17a and 17b. When the diameter of the wire harness a is smaller than the inner diameter, as shown in FIG.
Thereafter, the wire harness a is fixed to the wire convergence part 11 by wrapping the other convergence part piece 16a and the part fixed by the tape 19 with tape 20. To fix a thinner wire harness a to the wire convergence part 11, as shown in Fig. 6b,
Due to one of the convergence pieces 16b and the tape 19, the small diameter wire harness a has a small contact surface between the adhesive surface of the tape 19 and the wire harness a, making it impossible to fix it in the wire convergence part 11. Moreover, the centers of the wire harness a and the grommet do not match, which tends to cause the wire harness to be misaligned.

b is the width of the converging part within a predetermined length from the end.
The width of the convergent portion of the two convergent portions 6a and 6b is different from W1 and W2 . The length of the converging portion 6b that is different from the converging portion widths W 1 and W 2 is a length suitable for fixing a small-diameter wire harness, and is configured to be larger than the width of the tape to be wound. This will ensure strong adhesion during tape winding. 8a and 8b are portions formed at the ends of the convergence pieces 6a and 6b and projecting toward the outer periphery;
After each convergence piece 6a, 6b and the wire harness are fixed with tape, the tape is prevented from shifting and the wire harness is reliably fixed to each convergence piece 6a, 6b.
