Abstract

A wire harness has at least one electrically conducting path and an exterior member accommodating the electrically conducting path to protect the electrically conducting path. The exterior member has a heat reflecting portion provided at at least a portion of an outer surface of the exterior member to reflect external heat.

Claims

1. A wire harness comprising:

at least one electrically conducting path;

an exterior member accommodating the electrically conducting path to protect the electrically conducting path; and

a protector or a clamp attached to an outer surface of the exterior member such that both ends of the protector or the clamp with respect to a longitudinal direction of the exterior member are attached to the outer surface of the exterior member,

wherein the protector or the clamp comprises a heat reflecting portion provided at at least a portion of an outer surface of the protector or the clamp to reflect external heat, and

wherein the protector or the clamp is attached only to inflexible portions of the exterior member.

2. The wire harness according to claim 1, wherein the exterior member is configured to have a tubular body.

3. The wire harness according to claim 1, wherein the exterior member has a portion to be attached to a vehicle underfloor.

4. The wire harness according to claim 1, wherein the heat reflecting portion includes a coated portion on the outer surface of the heat reflecting portion.

5. The wire harness according to claim 1, wherein the heat reflecting portion includes a vapor-deposition layer.

6. The wire harness according to claim 1, wherein the heat reflecting portion includes a white or near-white light colored portion or a lustered portion.

7. The wire harness according to claim 1, wherein the heat reflecting portion includes a portion serving as a mirror.

8. The wire harness according to claim 1, wherein the heat reflecting portion includes a non-coated portion relative to the outer surface of the heat reflecting portion.

9. The wire harness according to claim 1, wherein the heat reflecting portion is provided at a position spaced apart from terminal ends of the exterior member.

10. The wire harness according to claim 1, wherein the heat reflecting portion of the protector or clamp is provided about substantially the entire outer periphery of the exterior member.
