To provide a branch portion protection structure and a branch portion protection method capable of protecting a branch portion with a simple structure.SOLUTION: In a wire harness 10 in which a plurality of bundled electric wires are inserted into a main tubular protective member 20 and a branch tubular protective member 50 which have flexibility, a branch portion protection structure 1 for protecting a branch portion 13 at which a branch line 12 is branched from a main trunk line 11 in a branching direction W includes a pipe-shaped main tubular protection member 20 into which the main trunk line 11 is inserted, and a pipe-shaped branch tubular protection member 50 into which a branch line 12 is inserted. The main tubular protection member 20 includes a first side main tubular protection member 30 arranged on a base end side Lb in an axial direction L with respect to the branch portion 13, and a second side main tubular protection member 40 arranged on a distal end side Lf in the axial direction with respect to the branch portion 13. At least a part of a tubular cross-section extends to a side of the branch tubular protection member 50 which faces the branch portion 13, and a branch extension portion 52 is provided so as to extend along outer surfaces of the first side main tubular protection member 30 and the second side main tubular protection member 40.SELECTED DRAWING: Figure 1

    【課題】簡易な構造で分岐部を保護できる分岐部保護構造及び分岐部保護方法を提供すること。【解決手段】束ねられた複数の電線が、可撓性を有する主管状保護部材20及び枝管状保護部材50の内部に挿通されたワイヤーハーネス10において、主幹線11から分岐方向Wに向かって枝線12が分岐された分岐部13を保護する分岐部保護構造1は、主幹線11が挿通する管状の主管状保護部材20と、枝線12が挿通する管状の枝管状保護部材50とが備えられ、主管状保護部材20は、分岐部13より軸線方向Lの基端側Lbに配置される第1側主管状保護部材30と、分岐部13より軸線方向Lの先端側Lfに配置される第2側主管状保護部材40とが備えられ、枝管状保護部材50の分岐部13に対向する側に、管状断面における少なくとも一部が延出され、第1側主管状保護部材30及び第2側主管状保護部材40の外面に沿う枝延出部52が設けられている。【選択図】図1
