The member may be a rod having a continuous convex arc surface extending in the longitudinal direction, and may be formed in a perfect circular cross section, a semicircular cross section, or the like. The convex arc surface does not need to have a constant arc curvature, and may be, for example, an elliptical arc obtained by combining a plurality of arc curvatures.

On the other hand, as the second member, it is sufficient that grooves having a substantially C-shaped cross section and a substantially U-shaped cross section capable of gripping the first member are continuous along the longitudinal direction, and the outer shape of the cross section is arbitrary. It is. As the concave arc surface, a cross-sectional shape and a radius of curvature corresponding to the cross-sectional shape of the convex arc surface may be appropriately selected in consideration of interposing a flat harness between the concave arc surface and the convex arc surface. Good. The first member and the second member preferably have the same length, but may have different lengths.

In the flat harness holder having the above-described structure, the second member grips the first member so that the convex arc surface and the concave arc surface face each other via the flat harness. Is maintained in a round shape corresponding to the radius of curvature of the convex arc surface and the concave arc surface, so that there is no possibility that the bent portion is crushed even when an impact is applied, and disconnection can be prevented. In addition, in this flat harness holder, the folding angle of the flat harness can be changed by appropriately selecting the intersection angle of the first member and the second member with respect to the longitudinal direction of the flat harness, and the versatility is higher than in the past. Is obtained.

Further, in the present invention, both ends of the first member and the second member are provided so that the first member and the second member do not relatively move along the longitudinal direction. One of the two end portions of the member has an engaging portion engageable with the other.

Here, as the engaging portion, a structure in which flanges are provided at both ends of the first member, a structure in which walls are provided at both ends of the groove in the second member, or the like can be adopted. In the flat harness holder configured as above, since the first member and the second member do not relatively move along the longitudinal direction by the engaging portion, the state where the flat harness is bent in a desired direction is reliably held. Will be.
