Abstract

A wire harness that is capable of protecting a wire even if a pipe is damaged includes: a wire disposed in a pipe; and a protective material surrounding and protecting a predefined portion of the wire, the predefined portion being disposed within the pipe. This configuration places the protective material on a portion that is likely to be damaged in the event of, for instance, a collision of a vehicle, thereby capable of protecting the wire even if the pipe is damaged. This configuration is also capable of avoiding the diameter of the pipe being increased for the process of passing the wire through the pipe, because the wire in this configuration is passed through the pipe with greater ease than a wire surrounded by a protective material along its entire length of the wire.

Claims

1. A wire harness, comprising:

a wire disposed in a pipe; and

a protective material surrounding and protecting a predefined portion of the wire, the predefined portion being disposed within the pipe.

2. The wire harness according to claim 1, comprising a plurality of wires disposed in the pipe,

the protective material being insulating and being placed individually on the wires.

3. The wire harness according to claim 1, wherein the protective material is made of high-strength fiber.

4. The wire harness according to claim 1, wherein the protective material is disposed on a portion of the wire that is located on an inner side of an edge of the pipe.
