Abstract

A wire harness includes a tubular external member and one or a plurality of conduction paths inserted into the external member and protected by the external member. The external member includes at least one fixed form insertion part in which an inside width is wider than an outside width of the one or the plurality of conduction paths, and a plurality of narrow-width insertion parts which are elastically deformable and in which an inside width is narrower than the outside width of the one or the plurality of conduction paths. The plurality of narrow-width insertion parts are arranged along a tube axial direction alternately and integrally with the at least one fixed form insertion part.

First claim

What is claimed is:

1. A wire harness comprising:
a tubular external member; and
one or a plurality of conduction paths inserted into the external member and protected by the external member,
wherein the external member includes at least one fixed form insertion part in which an inside width is wider than an outside width of the one or the plurality of conduction paths, and a plurality of narrow-width insertion parts which are elastically deformable and in which an inside width is narrower than the outside width of the one or the plurality of conduction paths, and
wherein the plurality of narrow-width insertion parts are arranged along a tube axial direction alternately and integrally with the at least one fixed form insertion part.

2. The wire harness according to claim 1 ,
wherein the plurality of narrow-width insertion parts reduce a play rate of the conduction path in the exterior member so as to suppress a vibration of the conduction path, have bellows tube shapes respectively, and regulate a bending direction of the wire harness.

3. A wire harness comprising:
an external member having a tubular shape; and
a conduction path inserted into the external member,
wherein the external member includes:
a fixed form insertion part; and
a narrow-width insertion part,

wherein, in the fixed form insertion part, an inside width of the external member is larger than an outside width of the conduction path throughout a whole circumference of the conduction path,
wherein, in the narrow-width insertion part, two points of an inner circumference of the external member elastically press corresponding points of an outer circumference of the conduction path toward radially inner sides of the conduction path to each other,
wherein the fixed form insertion part and narrow-width insertion part are alternatively arranged along a tube axial direction, and
wherein the fixed form insertion part and the narrow-width insertion part are integrally formed.

4. A manufacturing method for a wire harness including a tubular external member and a conduction path, the manufacturing method comprising:
preparing the external member, including a fixed form insertion part and a narrow-width insertion part which are alternatively arranged along a tube axial direction, the external member having an inside width which is larger than an outside width of the conduction path throughout a whole circumference of the conduction path, and the narrow-width insertion part having an inside width which is narrower than the outside width of the conduction path; and
inserting the conduction path into the exterior member while deforming the narrow-width insertion part.
