Abstract

Provided is a harness bending regulation member to be attached to a flexible harness protective tube, including: a high rigid unbendable portion into which an electric wire is inserted; and a bendable portion projecting in an axial direction of the unbendable portion from a tip end of one side of the unbendable portion, the bendable portion regulating a bending of the harness protective tube in a curved shape. The harness protective tube is routed from an oscillating member on a side close to a fixing structure to another oscillating member closer to a slide structure, the harness bending regulation member is placed inside of a harness holding tube on the side of the fixing structure, and the bendable portion is placed toward the slide structure along an inner surface of the harness protective tube.

First claim

The invention claimed is:

1. A harness bending regulation member inserted into a flexible harness protective tube, the member comprising:
a high rigid unbendable portion into which an electric wire is inserted; and
a bendable portion projecting in an axial direction of the harness bending regulation member from a tip end of one side of the unbendable portion, the bendable portion regulating a bending of the harness protective tube in a curved shape from inside of the harness protective tube.

2. The harness bending regulation member according to claim 1 , wherein the bendable portion includes a plurality of slits or grooves arranged in parallel.

3. The harness bending regulation member according to claim 2 , wherein projections are provided on end edges of the slits or the grooves, and deviation between opposed inner surfaces of the slits or the grooves generated when the inner surfaces abut against each other is absorbed by the projections.

4. A harness routing structure in which a harness protective tube is routed from an oscillating member on a side close to a fixing structure to another oscillating member on a side close to a slide structure, the harness bending regulation member according to claim 3 is placed in a harness holding tube on the side of the fixing structure, and the bendable portion is placed toward the slide structure along the harness protective tube.

5. The harness routing structure using the harness bending regulation member according to claim 4 , wherein a flange on a side close to a base end of the unbendable portion is axially movably engaged with a groove of the oscillating member on the side of the fixing structure.

6. A harness routing structure in which a harness protective tube is routed from an oscillating member on a side close to a fixing structure to another oscillating member on a side close to a slide structure, the harness bending regulation member according to claim 2 is placed in a harness holding tube on the side of the fixing structure, and the bendable portion is placed toward the slide structure along the harness protective tube.

7. The harness routing structure using the harness bending regulation member according to claim 6 , wherein a flange on a side close to a base end of the unbendable portion is axially movably engaged with a groove of the oscillating member on the side of the fixing structure.

8. A harness routing structure in which a harness protective tube is routed from an oscillating member on a side close to a fixing structure to another oscillating member on a side close to a slide structure, the harness bending regulation member according to claim 1 is placed in a harness holding tube on the side of the fixing structure, and the bendable portion is placed toward the slide structure along the harness protective tube.

9. The harness routing structure using the harness bending regulation member according to claim 8 , wherein a flange on a side close to a base end of the unbendable portion is axially movably engaged with a groove of the oscillating member on the side of the fixing structure.

10. The harness bending regulation member according to claim 1 , wherein the bendable portion is a spatulate portion.
