[0034] The flat wire harness 100 may be partially or entirely located within the wire groove 300. It is understood that "at least one" means one or more, and this does not limit the number of wire grooves 300 included in the rigid wire harness structure of this embodiment.
[0035] It is understandable that "at least two" means two or more. The number of fixing structures 400 provided on the conventional wire harness 200 in this embodiment can be specifically limited according to the actual situation, as long as they can serve to fix the conventional wire harness 200 and the flat wire harness 100.
