以上で説明したワイヤハーネス１、蓄電装置ユニット１０３は、充電導電路５０が充電インレット１０６と蓄電装置１０４とに渡って延在し電気を伝導する。この構成により、ワイヤハーネス１は、充電導電路５０を介して充電インレット１０６側から蓄電装置１０４に電力を供給し当該蓄電装置１０４を充電することができる。そして、ワイヤハーネス１は、充電導電路５０の少なくとも一部が板状導体２１によって構成される。この構成により、ワイヤハーネス１は、板状導体２１を含む被覆バスバ２の部分によって充電導電路５０の配索経路の少なくとも一部を規制することができる。またこの構成により、ワイヤハーネス１は、例えば、被覆電線３の部分と比較して、板状導体２１を含む被覆バスバ２の部分の断面積を相対的に抑制することができるので、大型化や重量増加を抑制することができる。この結果、ワイヤハーネス１、蓄電装置ユニット１０３は、車両Ｖへの搭載性を向上することができる。例えば、ワイヤハーネス１を流れる直流電力が相対的に高電圧化、大電流化した場合、充電導電路５０の導電部分の断面形状が大断面化してしまい、仮に、全て線状導体３１で構成した場合には、屈曲半径が大きくなり搭載性が低下するおそれがある。これに対して、ワイヤハーネス１は、ワイヤハーネス１を流れる直流電力が高電圧化、大電流化し、充電導電路５０の導電部分の断面形状が大断面化した場合であっても上記で説明したように車両Ｖへの搭載性向上を図ることができる。 In the wire harness 1 and the power storage device unit 103 described above, the charging conductive path 50 extends over the charging inlet 106 and the power storage device 104 to conduct electricity. With this configuration, the wire harness 1 can supply electric power to the power storage device 104 from the charging inlet 106 side via the charging conductive path 50 to charge the power storage device 104. Then, in the wire harness 1, at least a part of the charging conductive path 50 is composed of the plate-shaped conductor 21. With this configuration, the wire harness 1 can regulate at least a part of the wiring path of the charging conductive path 50 by the portion of the coated bus bar 2 including the plate-shaped conductor 21. Further, with this configuration, the wire harness 1 can be made larger because, for example, the cross-sectional area of the portion of the coated bus bar 2 including the plate-shaped conductor 21 can be relatively suppressed as compared with the portion of the coated electric wire 3. The weight increase can be suppressed. As a result, the wire harness 1 and the power storage device unit 103 can be mounted on the vehicle V. For example, when the DC power flowing through the wire harness 1 becomes relatively high voltage and large current, the cross-sectional shape of the conductive portion of the charging conductive path 50 becomes large, and it is assumed that all of them are made of linear conductors 31. In that case, the bending radius may become large and the mountability may decrease. On the other hand, the wire harness 1 has been described above even when the DC power flowing through the wire harness 1 is increased in voltage and current, and the cross-sectional shape of the conductive portion of the charging conductive path 50 is increased. As described above, the mountability on the vehicle V can be improved.

さらに、以上で説明したワイヤハーネス１、蓄電装置ユニット１０３は、充電導電路５０の他の一部が線状導体３１によって構成される。この構成により、ワイヤハーネス１は、線状導体３１を含む被覆電線３の部分が変形することで、例えば、梱包、輸送、配索、コネクタの嵌合等の各種作業を行う際の作業性を向上することができる。また、この構成により、ワイヤハーネス１は、車両Ｖへの組み付けや各部との接続の際に、当該線状導体３１を含む被覆電線３の部分によって各種の公差を吸収することができる。これらの点でも、ワイヤハーネス１、蓄電装置ユニット１０３は、車両Ｖへの搭載性を向上することができる。 Further, in the wire harness 1 and the power storage device unit 103 described above, the other part of the charging conductive path 50 is composed of the linear conductor 31. With this configuration, in the wire harness 1, the portion of the covered electric wire 3 including the linear conductor 31 is deformed, so that workability when performing various operations such as packing, transportation, wiring, and fitting of connectors can be improved. Can be improved. Further, with this configuration, the wire harness 1 can absorb various tolerances by the portion of the covered electric wire 3 including the linear conductor 31 when assembled to the vehicle V or connected to each portion. In these respects as well, the wire harness 1 and the power storage device unit 103 can improve the mountability on the vehicle V.

つまり、以上で説明したワイヤハーネス１、蓄電装置ユニット１０３は、板状導体２１を含む被覆バスバ２が線状導体３１を含む被覆電線３より高い剛性を有することで、当該板状導体２１を含む部分が相対的に高い形状保持機能を有し、充電導電路５０の経路規制部８を構成する。この構成により、ワイヤハーネス１は、板状導体２１を含む被覆バスバ２の部分が、例えば、曲げ部分等の形状保持性能が相対的に低い被覆電線３と比較してより確実に配索経路に応じた形状を維持することができる。この結果、ワイヤハーネス１は、例えば、コルゲートチューブ等の外装材を用いなくても、経路規制部８を構成する板状導体２１を含む部分によって充電導電路５０の配索経路を規制することができ、また、クランプ等の固定具の使用数も抑制することができる。一方、ワイヤハーネス１は、線状導体３１を含む被覆電線３が板状導体２１を含む被覆バスバ２より高い可撓性を有することで、当該線状導体３１を含む部分が相対的に高い形状可変機能を有し、充電導電路５０の変形許容部９を構成する。この構成により、ワイヤハーネス１は、線状導体３１を含む被覆電線３の部分が、例えば、形状保持性能が相対的に高い被覆バスバ２と比較して充電導電路５０の配索経路の変更や微調整に柔軟に対応することができる。この結果、ワイヤハーネス１は、例えば、変形許容部９を構成する線状導体３１を含む部分が変形することで種々の公差を吸収することができる。この結果、ワイヤハーネス１は、経路規制部８を構成する板状導体２１を含む部分によって充電導電路５０の配索経路に応じた形状を維持した上で変形許容部９を構成する線状導体３１を含む部分によって可動性も確保することができる。つまり、ワイヤハーネス１は、充電導電路５０の配索経路の形状保持機能と、充電導電路５０の配索経路の形状可変機能とを両立することができる。さらに言えば、ワイヤハーネス１は、相対的に高い剛性を有し配索経路に沿った良好な形状保持性を有する経路規制部８と、相対的に高い可撓性を有し良好な屈曲性を有する変形許容部９とを適正に組み合わせることできる。この構成により、ワイヤハーネス１は、当該ワイヤハーネス１における各部位に応じて要求される適正な可撓性と剛性とのバランスを実現することができ、良好な配索作業性や良好な取扱い性等を確保することができる。この結果、ワイヤハーネス１、蓄電装置ユニット１０３は、例えば、当該ワイヤハーネス１全体を車両Ｖに配索する際の作業性を向上することができ、車両Ｖへの搭載性を向上することができる。 That is, the wire harness 1 and the power storage device unit 103 described above include the plate-shaped conductor 21 because the coated bus bar 2 including the plate-shaped conductor 21 has higher rigidity than the coated electric wire 3 including the linear conductor 31. The portion has a relatively high shape-retaining function, and constitutes a path regulating portion 8 of the charging conductive path 50. With this configuration, in the wire harness 1, the portion of the coated bus bar 2 including the plate-shaped conductor 21 is more reliably routed to the wiring path than the coated electric wire 3 having a relatively low shape retention performance such as a bent portion. The corresponding shape can be maintained. As a result, the wire harness 1 can regulate the wiring path of the charging conductive path 50 by the portion including the plate-shaped conductor 21 constituting the path regulating portion 8 without using an exterior material such as a corrugated tube. In addition, the number of fixtures such as clamps used can be suppressed. On the other hand, the wire harness 1 has a shape in which the portion including the linear conductor 31 is relatively high because the coated electric wire 3 including the linear conductor 31 has higher flexibility than the coated bus bar 2 including the plate conductor 21. It has a variable function and constitutes a deformation allowable portion 9 of the charging conductive path 50. With this configuration, in the wire harness 1, the portion of the coated electric wire 3 including the linear conductor 31 can be changed, for example, by changing the wiring path of the charging conductive path 50 as compared with the coated bus bar 2 having a relatively high shape retention performance. It is possible to flexibly respond to fine adjustment. As a result, the wire harness 1 can absorb various tolerances by deforming, for example, the portion including the linear conductor 31 constituting the deformation allowable portion 9. As a result, the wire harness 1 maintains the shape corresponding to the wiring path of the charging conductive path 50 by the portion including the plate-shaped conductor 21 constituting the path regulating portion 8, and then forms the deformation allowable portion 9. Mobility can also be ensured by the portion including 31. That is, the wire harness 1 can have both a function of maintaining the shape of the wiring path of the charging conductive path 50 and a function of changing the shape of the wiring path of the charging conductive path 50. Furthermore, the wire harness 1 has a route regulating portion 8 having a relatively high rigidity and a good shape retention along the wiring path, and a wire harness 1 having a relatively high flexibility and a good flexibility. Can be appropriately combined with the deformation allowable portion 9 having the above. With this configuration, the wire harness 1 can realize a balance between appropriate flexibility and rigidity required for each part of the wire harness 1, and has good routing workability and good handleability. Etc. can be secured.
