Abstract

A wire harness includes an electrical pathway and a pipe like exterior member that covers the electrical pathway. The exterior member includes a low rigidity portion which is flelxible and a high rigidity portion which is unflexible and has a rigidity higher than the low rigidity portion, and the low rigidity portion and the high rigidity portion are successively arranged in an extending direction of the electrical pathway.

Claims

1. A wire harness comprising:

an electrical pathway;

a pipe like exterior member that covers the electrical pathway,

wherein the exterior member includes a low rigidity portion which is flelxible and a high rigidity portion which is unflexible and has a rigidity higher than the low rigidity portion, and

the low rigidity portion and the high rigidity portion are successively arranged in an extending direction of the electrical pathway.

2. The wire harness according to claim 1,

wherein the exterior member has a straight part, and an inner face of the straight part is formed with recesses, which become contactless with the electrical pathway when the electrical pathway is inserted.

3. The wire harness according to claim 1, wherein curved surfaces or tapers are formed at edges of the recesses.

4. The wire harness according to claim 1, wherein the electrical pathway is formed to have a length to pass though a vehicle floor and extend across the vehicle floor, and

the exterior member is also formed to have a length to pass though the vehicle floor and extend across the vehicle floor.

5. The wire harness according to claim 1, wherein the electrical pathways and the exterior member are formed to have a length to pass through a vehicle floor and extend across the vehicle floor, and

the high rigidity portion is formed to fit a shape of an attached portion of the vehicle floor to which the exterior member is attached.

6. The wire harness according to claim 5, wherein the high rigidity portion includes a first wall which faces the floor and a second wall which faces the ground, and

the first wall and the second wall are parallel to each other.

7. The wire harness according to claim 6, wherein the high rigidity portion includes two support walls which support the first wall and the second wall and are symmetrically arranged.

8. The wire harness according to claim 7, wherein the two support walls are formed into a curved shape in which each of center portions of the two support walls are away from each other.

9. The wire harness according to claim 7, wherein each of the two walls includes a deform part with which outer faces of the two walls are deformable toward outside and inner faces of the two walls are deformable in accordance with the deformation of the outer faces toward outside.
