BINDING STRUCTURE OF WIRE ROUTING MATERIAL

Provided is a binding structure of a wire routing material which can allow reduction of cost and also provides excellent workability for assembly into a vehicle body when wiring for wire routing materials having different shapes, such as a wire harness and a flat wire routing material, is performed in the vehicle body. A binding structure is formed in which a flexible wire routing material and a plate-shaped flat wire routing material having higher rigidity than the flexible wire routing material overlap each other, and the flexible wire routing material and the flat wire routing material are enclosed in an annular form, bound, and held by a binding portion of an engaging member including an engaging portion for assembly into the vehicle body.
