　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の少なくとも充電インレット１０６側の端部が板状導体２１によって構成され、当該板状導体２１の充電インレット１０６側の端部にインレット端子５が直付けされる。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充電インレット１０６側の端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。そして、ワイヤハーネス１は、板状導体２１を含む部分によって充電導電路５０の配索経路の少なくとも充電インレット１０６側の端部を規制した状態でインレット端子５を充電インレット１０６に保持させることで車両Ｖに組み付けられる。この構成により、ワイヤハーネス１は、板状導体２１の端部をインレット端子５を介して充電インレット１０６に接続することができる。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への組み付け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。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 charge the power storage device 104 by supplying power from the charging inlet 106 side to the power storage device 104 via the charging conductive path 50. In the wire harness 1, at least the end of the charging conductive path 50 on the charging inlet 106 side is constituted by the plate-like conductor 21, and the inlet terminal 5 is directly attached to the end of the plate-like conductor 21 on the charging inlet 106 side. The With this configuration, the wire harness 1 can regulate at least the end portion on the charging inlet 106 side of the routing path of the charging conductive path 50 by the portion of the covered bus bar 2 including the plate-like conductor 21. Further, with this configuration, the wire harness 1 can relatively suppress the cross-sectional area of the portion of the covered bus bar 2 including the plate-like conductor 21 as compared with the portion of the covered electric wire 3, for example. An increase in weight can be suppressed. And the wire harness 1 is a vehicle by hold | maintaining the inlet terminal 5 in the charging inlet 106 in the state which regulated the at least the edge part by the side of the charging inlet 106 of the wiring path | route of the charging conductive path 50 by the part containing the plate-shaped conductor 21. It is assembled to V. With this configuration, the wire harness 1 can connect the end portion of the plate-like conductor 21 to the charging inlet 106 via the inlet terminal 5. As a result, the wire harness 1 and the power storage device unit 103 can improve the assembling property to the vehicle V, and the mounting property to the vehicle V can be improved. For example, when the DC power flowing through the wire harness 1 has a relatively high voltage and large current, the cross-sectional shape of the conductive portion of the charging conductive path 50 becomes large, and all of the linear conductors 31 are temporarily configured. In such a case, there is a possibility that the bending radius becomes large and the mountability is lowered. In contrast, 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 in cross section. Thus, the mounting property to 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の蓄電装置１０４側の端部が線状導体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。つまり、ワイヤハーネス１は、充電導電路５０の充電インレット１０６側で板状導体２１を含む部分によって配索経路を適正に規制した上で、公差が生じ易い蓄電装置１０４側で線状導体３１を含む部分によって公差を適正に吸収することができる。ここでは、ワイヤハーネス１は、線状導体３１に接続端子６が設けられる。この構成により、ワイヤハーネス１は、線状導体３１の端部を接続端子６を介して蓄電装置１０４に接続することができる。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。 Furthermore, in the wire harness 1 and the power storage device unit 103 described above, the end portion on the power storage device 104 side of the charging conductive path 50 is configured by the linear conductor 31. With this configuration, the wire harness 1 has a workability when performing various operations such as packing, transportation, routing, connector fitting, etc., by deforming the portion of the covered electric wire 3 including the linear conductor 31. Can be improved. Also, 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 part. In other words, the wire harness 1 properly regulates the routing path by the portion including the plate-like conductor 21 on the charging inlet 106 side of the charging conductive path 50, and the linear conductor 31 on the power storage device 104 side where tolerance is likely to occur. The tolerance can be properly absorbed by the included part. Here, in the wire harness 1, the connection terminal 6 is provided on the linear conductor 31. With this configuration, the wire harness 1 can connect the end of the linear conductor 31 to the power storage device 104 via the connection terminal 6. Also in these points, the wire harness 1 and the power storage device unit 103 can improve the mountability to 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-like conductor 21 because the covered bus bar 2 including the plate-like conductor 21 has higher rigidity than the covered electric wire 3 including the linear conductor 31. The portion has a relatively high shape holding function, and constitutes the path regulating portion 8 of the charging conductive path 50. With this configuration, the wire harness 1 is more reliably routed in the portion of the covered bus bar 2 including the plate-like conductor 21 than, for example, the covered electric wire 3 having 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 routing path of the charging conductive path 50 by the portion including the plate-like conductor 21 constituting the path regulating unit 8 without using an exterior material such as a corrugated tube, for example. It is also possible to suppress the number of fixtures such as clamps used. On the other hand, the wire harness 1 has a shape in which the covered wire 3 including the linear conductor 31 has higher flexibility than the covered bus bar 2 including the plate-like conductor 21, so that the portion including the linear conductor 31 is relatively high. It has a variable function and constitutes the deformation allowing portion 9 of the charging conductive path 50. With this configuration, the wire harness 1 is configured such that the portion of the covered electric wire 3 including the linear conductor 31 is changed in the routing route of the charging conductive path 50 as compared with the covered bus bar 2 having a relatively high shape retention performance, for example. It can flexibly cope with fine adjustment. As a result, the wire harness 1 can absorb various tolerances, for example, by deforming a portion including the linear conductor 31 constituting the deformation allowing portion 9. As a result, the wire harness 1 maintains the shape according to the routing path of the charging conductive path 50 by the portion including the plate-shaped conductor 21 that configures the path regulating unit 8 and then forms the linear conductor that configures the deformation allowing unit 9. The portion including 31 can also ensure mobility. That is, the wire harness 1 can achieve both the shape holding function of the routing path of the charging conductive path 50 and the shape variable function of the routing path of the charging conductive path 50. Furthermore, the wire harness 1 has a relatively high rigidity and a path regulating portion 8 having a good shape retaining property along the routing path, and a relatively high flexibility and a good flexibility. And the deformation | transformation permission part 9 which has can be combined appropriately. With this configuration, the wire harness 1 can realize a balance between appropriate flexibility and rigidity required according to each part in the wire harness 1, and good routing workability and good handling properties.
