Abstract
A wire harness that includes: an exterior tube that is flexible and tubular; and electric wires inserted into the exterior tube, wherein the exterior tube is brought close to or into close contact with the electric wires by adjusting an internal pressure of the exterior tube to be lower than atmospheric pressure.
Claims4
A wire harness comprising:
- an exterior tube that is flexible and tubular;
- electric wires inserted into the exterior tube;
- and
- airtight seals that keep an internal space of the exterior tube airtight,
- wherein:
- the exterior tube is close to or in close contact with the electric wires due to an internal pressure of the exterior tube being lower than atmospheric pressure,
- the exterior tube is provided with a check valve that allows air in the exterior tube to flow out to an atmosphere, and restricts air from flowing into an interior of the exterior tube, and
- the check valve is positioned in an intermediate region between two airtight seals of the airtight seals, in an axial direction of the electric wires.
