Abstract

A wire harness includes: a wire harness main body in which a plurality of wires are bundled together; a first protective tube (protective tube) made of synthetic resin and enclosing the wire harness main body; a ring member provided so as to surround the first protective tube and fixated to a vehicle body via a clamp; and a holding mechanism holding the ring member and first protective tube so as to enable relative displacement within a predetermined tolerance range.

First claim

What is claimed is:

1. A wire harness comprising:
a wire harness main body in which a plurality of wires are bundled together;
a protective tube made of synthetic resin and enclosing the wire harness main body;
a ring member surrounding the protective tube and fixed to a vehicle body via a clamp; and
a holder holding the ring member and protective tube so as to enable relative displacement within a predetermined tolerance range;
the holder comprising a circumference direction projection projecting from an inner circumferential surface of the ring member, and a channel formed on an outer circumferential surface of the protective tube,
the projection having an inner diameter dimension greater than an outer diameter dimension of the channel, and the projection having an axial direction dimension smaller than an axial direction dimension of the channel, such that the projection fits into the channel with diameter direction clearance between the projection and the channel, and axial direction clearance between the projection and the channel.

2. The wire harness according to claim 1 , wherein the ring member has an accordion shape.

3. The wire harness according to claim 2 , wherein by fitting an engagement projection formed on an inner circumferential surface of the clamp into a recess on an outer circumferential surface of the ring member, the ring member and the clamp are fixed to each other.

4. The wire harness according to claim 1 , wherein the protective tube encloses a region around a length-direction portion of the wire harness main body,
a region of the wire harness main body not enclosed by the protective tube is enclosed by a second protective tube configured by synthetic resin; and
a region of the wire harness main body enclosed by neither the protective tube nor the second protective tube is enclosed by a rubber tube coupled at two ends to the protective tube and the second protective tube.

5. The wire harness according to claim 4 , wherein the wire harness main body includes a curved location, and the curved location is enclosed by the rubber tube.

6. A wire harness comprising:
a wire harness main body in which a plurality of wires are bundled together;
a protective tube made of synthetic resin and enclosing the wire harness main body;
a ring member surrounding the protective tube and fixated fixed to a vehicle body via a clamp; and
a holder holding the ring member and protective tube so as to enable relative displacement within a predetermined tolerance range;
the ring member having a constant inner diameter dimension, wherein the holder is an elastically deformable tape material placed between an outer circumferential surface of the protective tube and an inner circumferential surface of the ring member.

7. The wire harness according to claim 6 , wherein the clamp and ring member are fixed by adhesive tape.
