[0035] The cover door-side shaft 67 is provided upright in the upward direction Z1 at the end (the other end 2S of the exterior part 2) of the base-side third wall 56A opposite the cover-side hinge part 63. The cover door-side shaft 67 is provided at a position extending in the upward direction Z1 from the base door-side shaft 57 provided on the base-side member 5.

[0036] As shown in FIG. 2, the cover side hinge portion 63 is configured to have a pair of cover side continuous plates 68 (only the cover side continuous plate 68 is shown, the other is not shown) facing each other in the width direction of the cover side member 6.

[0037] One of the pair of cover side continuous plates 68 (hereinafter may be referred to as the "one-side cover side continuous plate 68") is provided between one of the pair of cover side second walls 64B, 64C (hereinafter may be referred to as the "one-side cover side second wall 64B") provided on the cover side body section 61 and one of the pair of cover side fourth walls 66B, 66C (hereinafter may be referred to as the "one-side cover side fourth wall 66B") provided on the cover side door section 62, and is provided in the form of a plate that is continuous with these and extends on the same plane as them.

[0040] When assembling such an exterior component 2, as shown in FIG. 2 , with the electric wire bundle W routed between the vehicle body B and the sliding door S (at the crossover portion 10), the base-side component 5 and the cover-side component 6 are positioned so that the extending direction of the electric wire bundle W is the same as the axial direction of the base-side component 5 and the cover-side component 6, and the base-side component 5 and the cover-side component 6 are assembled together with the electric wire bundle W sandwiched between them. The base-side component 5 and the cover-side component 6 may be locked with a locking structure (not shown) to maintain the assembled state of the base-side component 5 and the cover-side component 6. The exterior component 2 is assembled in this manner. At this time, the electric wire bundle W is sheathed by the exterior component 2.

[0041] As shown in FIG. 1, the body protector 3 is configured to include a vehicle body side base (not shown) having a base vehicle body side bearing (not shown) that supports a base vehicle body side shaft portion 55 provided on the exterior part 2, and a vehicle body side cover 31 that is assembled to the vehicle body side base and has a cover vehicle body side bearing (not shown) that supports a cover vehicle body side shaft portion 65 provided on the exterior part 2.

[0042] The vehicle-body-side base and vehicle-body-side cover 31 are fixed to the vehicle body B with bolts, with the base vehicle-body-side shaft 55 supported by the base vehicle-body-side bearing portion of the vehicle-body-side base and the cover vehicle-body-side shaft 65 supported by the cover vehicle-body-side bearing portion of the vehicle-body-side cover 31, and with one end 2B of the exterior component 2 sandwiched between them. As a result, one end 2B of the exterior component 2 is supported by the body protector 3 so as to be able to swing freely around an axis P1 extending in the up-down direction Z as its central axis.

[0043] As shown in FIG. 1 , the door protector 4 is configured to include a door side base (not shown) having a base door side bearing portion (not shown) that supports a base door side shaft portion 57 provided on the exterior part 2, and a door side cover 41 that is assembled to the door side base and has a cover door side bearing portion (not shown) that supports a cover door side shaft portion 67 provided on the exterior part 2.

[0044] The door-side base and the door-side cover 41 are fixed to the vehicle body B with bolts, with the base-door-side shaft 57 supported by the base-door-side bearing portion of the door-side base and the cover-door-side shaft 67 supported by the cover-door-side bearing portion of the door-side cover 41, and the other end 2S of the exterior component 2 sandwiched between them. As a result, the other end 2S of the exterior component 2 is supported by the door protector 4 so as to be able to swing freely around an axis P2 extending in the up-down direction Z as its central axis.

[0045] 2 , in a state where the electric wire bundle W is routed between the vehicle body B and the sliding door S (at the crossover section 10), the base-side member 5 and the cover-side member 6 are positioned so that the extending direction of the electric wire bundle W is the same as the axial direction of the base-side member 5 and the cover-side member 6, and the electric wire bundle W is sandwiched between the base-side member 5 and the cover-side member 6. The base-side member 5 and the cover-side member 6 are then assembled to assemble the exterior component 2. In this way, the electric wire bundle W is sheathed by the exterior component 2.

[0046] Thereafter, one end 2B of the exterior component 2 is positioned between the vehicle-body-side base and vehicle-body-side cover 31 that constitute the body protector 3, and the one end 2B of the exterior component 2 is sandwiched between the vehicle-body-side base and vehicle-body-side cover 31. At this time, the base vehicle-body-side shaft portion 55 provided on the base-side member 5 is journaled in the base vehicle-body-side bearing portion, and the cover body-side shaft portion 65 provided on the cover-side member 6 is journaled in the cover vehicle-body-side bearing portion. In this state, the vehicle-body-side base and vehicle-body-side cover 31 are bolted to predetermined positions on the vehicle main body B. As a result, the one end 2B of the exterior component 2 is supported so as to be able to swing freely around an axis P1 extending in the vertical direction Z as a central axis.

[0047] Furthermore, the other end 2S of the exterior component 2 is positioned between the door-side base and the door-side cover 41 that constitute the door protector 4, and the other end 2S of the exterior component 2 is sandwiched between the door-side base and the door-side cover 41. At this time, the base-door-side shaft 57 provided on the base-side member 5 is journaled in the base-door-side bearing, and the cover-door-side shaft 67 provided on the cover-side member 6 is journaled in the cover-door-side bearing. In this state, the door-side base and the door-side cover 41 are bolted to a predetermined position on the sliding door S. As a result, the other end 2S of the exterior component 2 is supported so as to be able to swing freely around the axis P2 extending in the up-down direction Z as the central axis.

[0048] This completes the assembly of the power supply device 1. In such a power supply device 1, as shown in Fig. 1 , as the sliding door S moves from a fully closed position (fully open position) to a half-open position (fully closed position), one end 2B of the exterior part 2 swings about an axis P1 as a central axis, and the other end 2S of the exterior part 2 swings about an axis P2 as a central axis, and the base-side hinge part 53 and the cover-side hinge part 63 are bent, thereby bending the exterior part 2 together with the wire bundle W.

[0049] According to the above-described embodiment, the exterior component 2 that exteriorizes the electric wires routed between the vehicle main body B (vehicle body) and the sliding door S has a base-side member 5 and a cover-side member 6 (a pair of members) for sandwiching the electric wire bundle W (electric wires), and is configured in a tubular shape that can exteriorize the electric wire bundle W. The base-side member 5 is configured to integrally include a base-side vehicle body portion 51 (vehicle body side portion) that is swingably supported by the vehicle main body B and formed to extend linearly, a base-side door portion 52 (door side portion) that is swingably supported by the sliding door S and formed to extend linearly, and a base-side hinge portion 53 (connecting portion), and the base-side hinge portion 53 is configured to be bendable so as to change the extending direction of the base-side vehicle body portion 51 and the base-side door portion 52. The cover side member 6 is integrally formed with a cover side body portion 61 (body side portion) that is supported so as to be freely swingable on the vehicle main body B and that extends in a straight line, a cover side door portion 62 (door side portion) that is supported so as to be freely swingable on the sliding door S and that extends in a straight line, and a cover side hinge portion 63 (connecting portion), and the cover side hinge portion 63 is configured to be bendable so as to change the extension direction of the cover side body portion 61 and the extension direction of the cover side door portion 62.

[0050] According to this, the transition section 10 does not require a body rotor configured with a body base and a body cover, a door rotor configured with a door base and a door cover, and a corrugated tube, as in the conventional technology. However, by including the exterior component 2 of this embodiment, it is possible to obtain a configuration in which the exterior component 2, which sheathes the wire bundle W, is bent when the sliding door S is opened or closed. By adopting such an exterior component 2, the body rotor, door rotor, and corrugated tube of the conventional technology can be omitted, thereby reducing the number of parts. Furthermore, by reducing the number of parts, manufacturing costs such as mold manufacturing costs can be reduced. Furthermore, if a common mold is used to mold the base side member 5 and the cover side member 6, manufacturing costs such as mold manufacturing costs can be further reduced.

[0051] Furthermore, since the exterior part 2 is composed of two parts for sandwiching the wire bundle W (electric wires), the work of closing the opening and closing lids provided on each block can be omitted compared to, for example, a caterpillar-type exterior material in which three or more blocks are connected by hinges and each block is provided with its own opening and closing lid, thereby reducing the assembly work time.

[0052] Furthermore, the cross-sectional area in a direction perpendicular to the axis of the exterior part 2 is formed such that the cross-sectional area of ​​the base-side hinge portion 53 (connecting portion) in the base-side member 5 (member) is smaller than the cross-sectional area of ​​the base-side body portion 51 and the base-side door portion 52, which are other portions of the base-side member 5. Furthermore, the cross-sectional area of ​​the cover-side hinge portion 63 (connecting portion) in the cover-side member 6 (member) is formed such that it is smaller than the cross-sectional area of ​​the cover-side body portion 61 and the cover-side door portion 62, which are other portions of the cover-side member 6. This allows the hinge portions 53, 63 to be more easily deformed than the other portions, and the base-side hinge portion 53 realizes a configuration in which the base-side body portion 51 and the base-side door portion 52 are bent to change their extending directions, and the cover-side hinge portion 63 realizes a configuration in which the cover-side body portion 61 and the cover-side door portion 62 are bent to change their extending directions.

[0053] Although the best configurations and methods for carrying out the present invention have been disclosed above, the present invention is not limited thereto. That is, although the present invention has been particularly illustrated and described primarily with reference to specific embodiments, those skilled in the art can make various modifications to the above-described embodiments in terms of shape, material, quantity, and other detailed configurations without departing from the scope of the technical idea and purpose of the present invention. Therefore, the above-disclosed descriptions limiting the shapes, materials, etc. are provided as examples to facilitate understanding of the present invention and are not intended to limit the present invention. Therefore, descriptions using names of components that are free from some or all of the limitations on the shapes, materials, etc. are included in the present invention. [Explanation of symbols]
