Abstract

Tubes are connected to each other by a tube connecting part such that a distance between respective ends of the tubes is an optional distance or such that the ends of the tubes abut each other.

First claim

What is claimed is:

1. A wire harness exterior member comprising:
at least two types of tubes, each having a desired length;
a tube connecting part connecting the different types of tubes to each other,
the tube connecting part comprising a cylindrical inner surface surrounding ends of the tubes,
the cylindrical inner surface comprising an inwardly protruded portion at which at least one of the ends of the tubes is arranged; and
a waterproof structure comprising
a first tube engaging portion provided on one side of the inwardly protruded portion and engaging with one of the tubes that are connected to each other,
and a second tube engaging portion provided on an opposite side of the inwardly protruded portion and engaging with the other of the tubes that are connected to each other,
wherein the first tube engaging portion is provided to fill a space between the one of the tubes and the cylindrical inner surface of the tube connecting part,
and the second tube engaging portion is provided to fill a space between the other of the tubes and the inner surface of the tube connecting part in a radial direction,
such that the first tube engaging portion and the second tube engaging portion prevent the tubes from rotating and sliding,
and such that the distance between the ends of the tubes corresponds to a variance between the length of the two tubes and the desired length of the two tubes.

2. The wire harness exterior member according to claim 1 , wherein the tubes comprise a flexible tube formed as a flexible portion and an inflexible tube formed as an inflexible portion.

3. The wire harness exterior member according to claim 2 , wherein the flexible tube has a shape of a corrugated tube.

4. The wire harness exterior member according to claim 1 , wherein the tube connecting part is a post-attached part having at least one function other than a function to connect the tubes to each other.

5. The wire harness exterior member according to claim 4 , wherein the tube connecting part comprises a fixing portion having a cantilever shape, the fixing portion being configured to hold the tubes that are connected to each other on a vehicle underfloor portion.

6. The wire harness exterior member according to claim 5 , wherein the fixing portion comprises a bolt insertion hole.

7. The wire harness exterior member according to claim 1 , wherein the tube connecting part comprises two tube attachments, each of the tube attachments having a semi-cylindrical inner surface.

8. The wire harness exterior member according to claim 7 , wherein the tube connecting part further comprises a hinge connecting the tube attachments to each other.

9. A wire harness comprising:
a wire harness exterior member;
a conducting path covered by the wire harness exterior member,
wherein the wire harness exterior member comprises:
at least two types of tubes, each having a desired length;
a tube connecting part connecting the different types of tubes to each other,
the tube connecting part comprising a cylindrical inner surface surrounding ends of the tubes,
the cylindrical inner surface comprising an inwardly protruded portion at which at least one of the ends of the tubes is arranged; and
a waterproof structure comprising a first tube engaging portion provided on one side of the inwardly protruded portion and engaging with one of the tubes that are connected to each other,
and a second tube engaging portion provided on an opposite side of the inwardly protruded portion and engaging with the other of the tubes that are connected to each other,
wherein the first tube engaging portion is provided to fill a space between the one of the tubes and the cylindrical inner surface of the tube connecting part,
and the second tube engaging portion is provided to fill a space between the other of the tubes and the cylindrical inner surface of the tube connecting part in a radial direction,
such that the first tube engaging portion and the second tube engaging portion prevent the tubes from rotating and sliding,
and such that the distance between the ends of the tubes corresponds to a variance between the length of the two tubes and the desired length of the two tubes.
