- the path maintaining member has a configuration covering the outer peripheral side of the corrugated tube, it is necessary to set the path maintaining member to a size larger than the outer diameter of the corrugated tube. For this reason, the overall shape of the path maintaining member becomes large, which causes a cost increase.

It is set larger than (dimension). For this reason, the first portion 134 is more rigid than the second portion 234.
- the first portion 134 where the path maintaining member 130 is bent relatively abruptly that is, the first portion 134 that maintains the wire harness main body 12 and the corrugated tube 20 in a relatively abruptly bent state. Since the wire harness body 12 and the corrugated tube 20 are bent relatively abruptly, the wire harness body 12 and the corrugated tube 20 can be more reliably maintained constant. Further, in the second portion 234 where the path maintaining member 130 is not bent relatively abruptly, the arc-shaped portion 232 can be reduced in size in the width direction. This makes it easy to mold a three-dimensional shape and also reduces the amount of resin used.
