Abstract

There is provided a harness-fixing construction of a grommet in which an upwardly-extending wire assembly portion can be positively fixed to a tubular portion of the grommet, and the efficiency of a wire harness-installing operation is enhanced. The grommet includes a proximal portion for fitting watertight in a panel hole, the tubular portion of a generally L-shape extending downwardly from the proximal portion, and a protuberance portion which is formed integrally with the proximal portion and the tubular portion, and has a concave surface. The grommet has a passage hole for passing a fastening band (fixing member) therethrough. A holding mechanism for stably holding the upwardly-extending wire assembly portion in a desired position is formed by the passage hole for passing the fastening band therethrough, and the protuberance portion having the concavely-curved surface for holding the upwardly-extending wire assembly portion in a generally embracing manner. This concave surface extends in a direction of the length of the tubular portion, and the upwardly-extending wire assembly portion, when fitted in the concave surface in the longitudinal direction, is positioned properly.

Claims

1. A grommet in combination with a wire, comprising:

a proximal portion for holding said wire;

a tubular portion formed integrally with said proximal portion for directing said wire downwardly,

wherein said wire includes a downward wire portion downwardly extended from said tubular portion, a drain portion provided by bending said downward wire portion substantially into a U-shape and a upward wire portion upwardly extended from said drain portion;

a fixing member fixing said upward wire portion to said tubular portion; and

a holding mechanism for holding said upward wire portion in a predetermined position, said holding mechanism formed at least on either said proximal portion or said tubular portion.

2. The grommet in combination with a wire of claim 1, wherein said holding mechanism includes a passage hole for holding said fixing member.

3. The grommet in combination with a wire of claim 2, wherein said passage hole is formed around said tubular portion and extended in a direction perpendicular to a length of said tubular portion.

4. The grommet in combination with a wire of claim 3, wherein a front hole is formed on said tubular portion for holding said fixing member.

5. The grommet in combination with a wire of claim 4, wherein said front hole is formed proximate said upward wire portion.

6. The grommet in combination with a wire of claim 1, wherein said holding mechanism includes passage holes for holding said fixing member.

7. The grommet in combination with a wire of claim 6, wherein said passage holes are formed respectively on opposite sides of a front side of said tubular portion.

8. The grommet in combination with a wire of claim 7, wherein said passage holes are formed proximate said upward wire portion.

9. The grommet in combination with a wire of claim 1, wherein said fixing member includes a band.

10. The grommet in combination with a wire of claim 1, wherein said holding mechanism includes a protuberance portion reducing a movement of said upward wire portion.

11. The grommet in combination with a wire of claim 1, wherein said holding mechanism includes a protuberance portion having a concave surface for holding said upward wire portion.

12. The grommet in combination with a wire of claim 11, wherein said protuberance portion is integrally formed with said proximal portion and said tubular portion.

13. The grommet in combination with a wire of claim 11, wherein said concave surface is extended in a direction of a length of said tubular portion.

14. The grommet in combination with a wire of claim 1, wherein said holding mechanism includes a passage hole for holding said fixing member, and a protuberance portion having a concave surface for holding said upward wire portion.

15. The grommet in combination with a wire according to claim 2 wherein the fixing member includes a band and a lock member.

16. The grommet in combination with a wire according to claim 2 wherein the passage hole is located adjacent to the proximal portion and the passage hole has at least one interior surface that extends in a generally coplanar direction as the proximal portion.
