  The power supply apparatus according to the first embodiment of the present invention will be described below with reference examples partially.

  FIG. 1 is a diagram illustrating a power supply apparatus according to a first embodiment of the present invention, partially with reference examples. The power feeding device 1 according to the present embodiment is a device that is electrically connected via a wire harness 110 routed between the vehicle body 60 and the slide door 50 in the vehicle 5 having the vehicle body 60 and the slide door 50. In FIG. 1, the right side in the figure corresponds to the front side of the vehicle 5, the left side in the figure corresponds to the rear side of the vehicle 5, the upper side in the figure corresponds to the outside of the vehicle 5, and the lower side in the figure corresponds to the vehicle 5. It corresponds to the inside. Also, the vertical direction in the figure is the X direction in the present embodiment, the horizontal direction in the figure is the Y direction in the present embodiment, and the direction perpendicular to the paper surface is the Z direction.

  In the power feeding device 1, electric power is supplied from a power source (not shown) provided on the vehicle body 60 to an electric device (not shown) provided on the slide door 50 via the wire harness 110. In the power supply device 1, electrical signals are also exchanged between the control means (not shown) provided on the vehicle body 60 and the electric equipment (not shown) provided on the slide door 50 via the wire harness 110. The power feeding device 1 includes a wire harness 110, a corrugated tube 120, a bending restriction member 130, a door side holding part 140, and a vehicle body side holding part 150.

  In the wire harness 110, a plurality of electric wires 111 are bundled, and a portion between the vehicle body 60 and the slide door 50 in the wire harness 110 is passed through a corrugated tube 120 which is a resin-made flexible tube. . The bending regulating member 130 is disposed between the inner surface of the corrugated tube 120 and the wire harness 110 so as to surround the wire harness 110 in the circumferential direction and along the wire harness 110. The bending restricting member 130 will be described in detail later.

  One end of the corrugated tube 120 on the slide door 50 side is held by the door-side holding unit 140 so as to be swingable on the XY plane with the Z direction, which is the vertical direction of the vehicle 5, as the swing axis direction. The door side holding part 140 is fixed to the slide door 50. The door-side swing shaft 141 along the Z direction provided in the door-side holding unit 140 is parallel to the slide door 50 and orthogonal to the opening / closing direction D11 of the slide door 50 (Y direction which is the front-rear direction of the vehicle 5). It is the axis. One end of the corrugated tube 120 on the slide door 50 side is held by the door-side holding portion 140 so as to be swingable around the door-side swing shaft 141. By holding the corrugated tube 120 by the door-side holding part 140, a part of the wire harness 110 on the slide door 50 side is held swingably on the XY plane around the door-side swing shaft 141. The slide door 50 side of the wire harness 110 protrudes from one end of the corrugated tube 120 on the slide door 50 side. Furthermore, the wire harness 110 extends from the door-side holding part 140 through an unillustrated passage inside the door-side holding part 140 and then extends to the electrical device of the slide door 50.

  On the other hand, one end of the corrugated tube 120 on the vehicle body 60 side is held by the vehicle body side holding portion 150 so as to be swingable on the XY plane with the Z direction, which is the vertical direction of the vehicle 5, as the swing axis direction. The vehicle body side holding part 150 is fixed to the vehicle body 60. A vehicle body side swing shaft 151 along the Z direction provided in the vehicle body side holding portion 150 is an axis parallel to the slide door 50 and perpendicular to the opening / closing direction D11 of the slide door 50. One end of the corrugated tube 120 on the vehicle body 60 side is held by the vehicle body side holding portion 150 so as to be swingable about the vehicle body side swing shaft 151. By holding the corrugated tube 120 by the vehicle body side holding portion 150, a part of the wire harness 110 on the vehicle body 60 side is held so as to be swingable around the vehicle body side swing shaft 151 on the XY plane. The vehicle body 60 side of the wire harness 110 exits from one end of the corrugated tube 120 on the vehicle body 60 side, and further passes through a passage (not shown) inside the vehicle body side holding portion 150 and also exits from the vehicle body side holding portion 150. The vehicle body 60 extends to a power source and control means (not shown).

  When the sliding door 50 is fully closed, the door-side holding portion 140 is located on the front side of the vehicle 5 with respect to the vehicle body-side holding portion 150 as shown in FIG. The corrugated tube 120, that is, the wire harness 110 inside the corrugated tube 120, extends in a substantially linear state between the vehicle body side holding portion 150 and the door side holding portion 140.

  When the slide door 50 is opened in the opening direction D111 toward the rear of the vehicle 5, at the initial stage, one end of the corrugated tube 120 on the slide door 50 side swings as follows. That is, the one end swings on the XY plane so as to move away from the slide door 50 and toward the front side of the vehicle 5 in the direction opposite to the opening direction D111. Here, a reference example of the configuration related to the swing will be described first. In this reference example, the door-side holding portion 140 is provided with a coil spring to promote such swinging. The coil spring urges one end of the corrugated tube 120 on the slide door 50 side in the urging direction D12 that is separated from the slide door 50 and is directed in the direction opposite to the opening direction D111 of the slide door 50. Hereinafter, unless otherwise specified, the configuration relating to the swing will be described by referring to an embodiment employing a reference example.

  By swinging as described above in the initial stage of opening the sliding door 50, the wire harness 110 inside the corrugated tube 120 is next moved during the subsequent movement of the sliding door 50 in the opening direction D111, that is, when the sliding door 50 is half open. Bend like That is, as shown in FIG. 1, the wire harness 110 draws a U-shape on the XY plane so as to protrude from the vehicle body side holding portion 150 to the door side holding portion 140 on the front side of the vehicle 5. It bends in the permissible direction D13 and curves toward the outside of 60.

  In the following description, the wire harness 110 inside the corrugated tube 120 may be simply referred to as the wire harness 110 without particular notice.

  The U-shaped curve as described above reduces the burden on the corrugated tube 120 and the wire harness 110 compared to, for example, the case where the wire harness 110 is bent into an S shape on the XY plane.

  During movement of the sliding door 50 in the opening direction D111, the arm on the sliding door 50 side in the U-shape of the wire harness 110 moves toward the front side of the vehicle 5 by the urging in the urging direction D12 by the door side holding portion 140. And straightened. At this time, the arm on the vehicle body 60 side is extended linearly toward the front side of the vehicle 5. The U shape of the wire harness 110 on the XY plane of the wire harness 110 during the movement of the slide door 50 is adjusted by the behavior of each part and the action of the bending restriction member 130 described later.

  As the slide door 50 moves in the opening direction D111, the arm on the slide door 50 side in the U-shape of the wire harness 110 extends and the arm on the vehicle body 60 side shortens. Then, when the arm on the vehicle body 60 side is shortened to some extent, one end of the wire harness 110 on the vehicle body 60 side swings in the swing direction D15 toward the rear side of the vehicle 5. Thereafter, in this state, the slide door 50 moves in the opening direction D111 and reaches the fully open state.

  When the sliding door 50 is closed in the closing direction D112 from the fully opened state, the wire harness 110 follows the reverse operation to that when the sliding door 50 is opened. First, at the initial stage, one end of the wire harness 110 on the vehicle body 60 side swings in a direction opposite to the swing direction D15, so that the wire harness 110 becomes U-shaped on the XY plane. Thereafter, when the sliding door 50 continues to move in the closing direction D112 and the arm on the sliding door 50 side in the U-shape is shortened to some extent, one end on the sliding door 50 side of the wire harness 110 swings as follows. . That is, at this stage, one end of the wire harness 110 on the slide door 50 side is opposed to the urging by the door-side holding portion 140 and is opposite to the urging direction D12 to the rear side of the vehicle 5. Swing. Thereafter, in this state, the slide door 50 moves in the closing direction D112, and the wire harness 110 reaches the fully closed state while being extended in a straight line state.

  Here, the end on the slide door 50 side of the floor of the vehicle body 60 is lowered one step, and is a step 61 in which the occupant puts his or her feet when boarding. When the sliding door 50 is opened and closed, the arm on the vehicle body 60 side of the U-shaped wire harness 110 as described above passes near the step 61 on the XY plane.

  At this time, generally, in the field of a power feeding device attached to a slide door of a vehicle, there is a demand for suppressing swelling to the vehicle body side when the wire harness is bent when the slide door is opened and closed. Therefore, in the present embodiment, a bending regulating member 130 arranged along the wire harness 110 is provided in order to regulate the bending that causes the wire harness 110 to bulge toward the vehicle body 60 in this way. The bending regulating member 130 restricts the wire harness 110 to bend on the XY plane. Then, the bending restriction member 130 allows the bending in the allowable direction D13 in which the wire harness 110 is bent toward the outside of the vehicle body 60 on the XY plane. On the other hand, with respect to the regulation direction D16 that bends the wire harness 110 to the inside of the vehicle body 60 on the side opposite to the permissible direction D13, the bending beyond a predetermined limit state is regulated.

  FIG. 2 is a perspective view showing the bending restricting member shown in FIG.

  As shown in FIG. 1, the bending regulating member 130 is surrounded by the wire harness 110 between the inner surface of the corrugated tube 120 and the wire harness 110 so as to surround the wire harness 110 in the circumferential direction. Arranged to induce curvature. The bending regulating member 130 has substantially the same length as the corrugated tube 120. In FIG. 2, the right end portion of the bending regulating member 130 is the vehicle body 60 side, and the left end portion is the slide door 50 side.

  The bending regulating member 130 includes a plurality of member pieces 131 arranged along the wire harness 110 and a connecting portion 132 that connects the plurality of member pieces 131 adjacent to each other. In this embodiment, the several member piece 131 and the connection part 132 are mutually shape | molded integrally with resin. 2 follows the wire harness 110 that is bent in the allowable direction D13 on the XY plane shown in FIG. 1 and is bent into a U shape, and is bent in the same U shape. It is shown. The connecting portion 132 is a flexible member that is disposed along the wire harness 110 so as to be positioned inside the curved shape when the wire harness 110 is bent in this way.

  FIG. 3 is a diagram showing one of a plurality of member pieces constituting the bending regulating member shown in FIG. 2 as a representative example. 3A is a perspective view of the member piece 131, and FIG. 3B is a cross-sectional view showing a V11-V11 cross section in FIG. 3A.

  Each of the plurality of member pieces 131 includes a pair of opposing walls 1311 facing each other so as to sandwich the wire harness 110 therebetween, and a pair of opposing walls 1311 as shown in a representative example in FIG. A connecting wall 1312 to be connected. With each of these three walls, each member piece 131 has a substantially C-shaped cross section that intersects the length direction D17 of the wire harness 110 as shown in FIG.

  Each of the pair of opposing walls 1311 has a substantially T-shape in plan view as shown in FIG. The portion corresponding to the T-shaped horizontal bar extending in the length direction D17 of the wire harness 110 is formed wide, and the portion corresponding to the T-shaped vertical bar crossing the length direction D17 is narrow and short. Is formed. The base of the narrow portion of each T-shaped opposing wall 1311 is connected to the coupling wall 1312. The coupling wall 1312 connects the narrow portions.

  Moreover, the outer surface on the opposite side to the wire harness 110 in each of a pair of opposing wall 1311 becomes uneven | corrugated shape by which the reinforcement rib 1311a was assembled in the grid | lattice form. The envelope shape of the outer surface provided with the reinforcing rib 1311 a is a convex curved surface along the inner surface of the corrugated tube 120. And the both end surfaces 1311b of the wide part of each opposing wall 1311 of the length direction D17 become a wedge-shaped surface substantially with the side surface shape of the reinforcement rib 1311a as it is.

  The plurality of member pieces 131 are arranged along the wire harness 110 so that the wedge-shaped end surfaces 1311b of the opposing walls 1311 of the member pieces 131 face each other.

  In this embodiment, the coupling wall 1312 that connects the pair of opposing walls 1311 is inside the curved shape of the wire harness 110, that is, inside the curved shape when bending in the allowable direction D13 as shown in FIG. A plurality of member pieces 131 are arranged so as to be positioned. And the connection part 132 has connected the coupling walls 1312 of the member piece 131 adjacent to each other. Further, the connecting portion 132 is a plate-like member as shown in FIG. 3A, and has a thickness that can be bent in either the allowable direction D13 in FIG. 2 or the opposite direction. Thinly formed. Furthermore, the bending restricting member 130 is arranged such that the plate-like connecting portion 132 is orthogonal to the XY plane shown in FIG. As a result, the bending of the bending regulating member 130 is limited on the XY plane, and as a result, the bending of the wire harness 110 is also limited on the XY plane.

  Further, in the present embodiment, the member piece 131a located at the right end in FIG. 2, that is, the end on the vehicle body 60 side, in the bending restricting member 130 is formed on the vehicle body side holding portion 150 shown in FIG. And held together with the end of the corrugated tube 120. On the other hand, the member piece 131b located at the left end in FIG. 2 of the bending restricting member 130, that is, the end on the slide door 50 side, is held by the door-side holding portion 140 shown in FIG. Absent. Accordingly, the member piece 131b can be brought into contact with and separated from the door-side holding portion 140 in accordance with the bending of the bending restriction member 130. As shown in FIG. 2, the member piece 131 a on the vehicle body 60 side is provided with a flange 131 a-1 for holding the member piece 131 a on the vehicle body side holding portion 150.

  4 is a schematic cross-sectional view taken along the line V12-V12 in FIG. 1, showing that the vehicle body side member piece of the bending regulating member is held by the vehicle body side holding portion.

  The vehicle body side holding portion 150 is fixed to the vehicle body 60, and the swinging portion 152 is supported by the fixing portion 152 so as to be swingable around the vehicle body swinging shaft 151 shown in FIG. Part 153. An insertion hole 153a through which the wire harness 110 is passed is provided inside the swinging portion 153, and the insertion hole 153a opens to the slide door 50 side. The end of the corrugated tube 120 on the vehicle body 60 side is fixed to the opening 153b of the swinging portion 153. Further, a fitting groove 153c into which the flange 131a-1 of the member piece 131a on the vehicle body 60 side of the bending regulating member 130 exposed from the end portion of the corrugated tube 120 on the vehicle body 60 side is fitted is formed on the back side of the opening 153b. ing. By fitting the flange 131a-1 in the fitting groove 153c, the member piece 131a on the vehicle body 60 side of the bending regulating member 130 is held by the vehicle body side holding portion 150 together with the end portion of the corrugated tube 120. The vehicle body side holding part 150 may be provided with a biasing member such as a coil spring that biases the swinging part 153 in the direction opposite to the swinging direction D15 shown in FIG. The urging by the urging member serves to assist the linear extension of the body 60 side of the wire harness 110 to the front side of the vehicle 5.

  In this way, the bending restricting member 130 in which the end member piece 131a is held by the vehicle body side holding portion 150 is limited to the bending on the XY plane shown in FIG. 1 and the allowable direction on the XY plane. D13 can be bent. The bending regulating member 130 is incapable of bending beyond a limit state described later in a regulating direction D16 that is directed to the inside of the vehicle body 60 on the side opposite to the allowable direction D13.

  FIG. 5 shows that the bending restricting member can be bent in the allowable direction shown in FIG. 1, and the restricting direction opposite to the allowable direction cannot be bent beyond the limit state. FIG. FIG. 5A shows a state in which the bending restricting member 130 can be bent in the allowable direction D13. FIG. 5B shows that the bending restricting member 130 is not bendable beyond the limit state in the restricting direction D16.

  In the permissible direction D13, as shown in FIG. 5A, the connecting portions 132 are adjacent to each other at the curved portion among the plurality of member pieces 131 while being separated from each other on the side opposite to the connecting portion 132. By bending, the bending regulating member 130 can be bent. Thereby, the wire harness 110 is allowed to bend in the allowable direction D13.

  On the other hand, regarding the regulation direction D16, as shown in FIG. 5 (B), the adjacent ones of the plurality of member pieces 131 at the curved portion are in contact with each other on the side opposite to the connecting portion 132, The bending restricting member 130 is not bendable beyond the limit state. A state in which adjacent ones in the curved portion are in contact with each other is a limit state in bending in the restriction direction D16, and the bending restriction member 130 cannot bend in the restriction direction D16 beyond this limit state. As a result, the wire harness 110 is restricted from bending in the restriction direction D <b> 16 so as to bend beyond the limit state in the bending restriction member 130.

  In the present embodiment, the arrangement direction of the plurality of member pieces 131 (that is, the length direction D17 of the wire harness 110) except for a part in the vicinity of the vehicle body side holding portion 150, which will be described later, has a substantially total length including the middle. The bending regulating member 130 is configured as follows. That is, as shown in FIG. 5 (B), the adjacent member pieces 131 are opposite to the connecting portion 132 when the bending restricting member 130 is in a substantially straight state as shown in FIG. It is comprised so that it may mutually contact | abut on the side. That is, in the present embodiment, the limit state of the regulation direction D16 is set to a substantially linear state for a portion excluding a part in the vicinity of the vehicle body side holding portion 150. Thereby, a substantially linear shape is maintained except the part which curves in the allowable direction D13 in the wire harness 110.

  Here, as shown in FIG. 1, in the present embodiment, the swing range on the XY plane of the end portion of the wire harness 110 in the vehicle body side holding portion 150 in the regulation direction D16 is as follows. It has become. That is, the swing range is a range in which the end portion of the wire harness 110 stops before one step of moving the wire harness 110 in parallel with the opening / closing direction D11 of the slide door 50. For this reason, in the present embodiment, the bending restriction member 130 is configured so that a part of the vicinity of the vehicle body side holding portion 150 can be bent to some extent in the restriction direction D16 by slightly relaxing the restriction on the bending in the restriction direction D16. Has been. As a result, a part of the wire harness 110 in the vicinity of the vehicle body side holding portion 150 is slightly curved in the regulation direction D16, and the portion in which the substantially linear shape is maintained as described above is parallel to the opening / closing direction D11 of the slide door 50. Can be directed to.

  FIG. 6 is a diagram illustrating a state where the restriction on the bending in the restriction direction of the wire harness is slightly relaxed for a part in the vicinity of the vehicle body side holding portion in the bending restriction member. FIG. 6A shows the bending restricting member 130 when a part of the wire harness 110 near the vehicle body side holding portion 150 is in a substantially straight state. FIG. 6B shows a state in which further bending is restricted by the bending restriction member 130 when the wire harness 110 is bent so as to bend in the restriction direction D16 to some extent with respect to the above portion.

  As shown in FIG. 6A, in the bending regulating member 130, the length L11 in the length direction D17 of the wire harness 110 of the member piece 131c is a part of the vicinity of the vehicle body side holding portion 150. The length L12 of the other member 131 is slightly shorter. As a result, the gaps d11 and d12 are opened between the member pieces 131c and 131 for a part of the vicinity of the vehicle body side holding portion 150 even when the bending restricting member 130 is in a substantially straight state. For this reason, as shown in FIG. 6 (B), this portion until the adjacent member pieces 131c, 131 come into contact with each other on the opposite side of the connecting portion 132 and the gaps d11, d12 are closed. The connecting portion 132 bends in the regulation direction D16. By bending the connecting portion 132 in this way, the bending restricting member 130 can be bent so as to be bent to some extent in the restricting direction D16. Thereby, about the part of the vicinity of the vehicle body side holding | maintenance part 150, the control with respect to the curve of the control direction D16 of the wire harness 110 will be loosened a little. The state shown in FIG. 6B is a limit state for a part of the bending regulating member 130 in the vicinity of the vehicle body side holding portion 150.

  As described above, in the present embodiment, in the bending restriction member 130, the interval between the plurality of member pieces 131 is set in the arrangement direction (long) in a substantially straight state that is not curved in any of the allowable direction D13 and the restriction direction D16. In the direction D17). That is, as shown in FIG. 5 (B), in the portion extending over substantially the entire length excluding a part in the vicinity of the vehicle body side holding portion 150, the interval between the member pieces 131 in the substantially linear state is substantially zero. In the vicinity of the vehicle body side holding portion 150, gaps d11 and d12 as shown in FIG. As a result, in the bending restricting member 130, the limit state for the bending in the restricting direction D16 is different as described above in two portions, that is, a portion in the vicinity of the vehicle body side holding portion 150 and the other portions. .

  The bending restricting member 130 of the first embodiment described above can be bent in the allowable direction D13. On the other hand, in the regulation direction D16 on the opposite side, the adjacent ones of the plurality of member pieces 131 at the curved portions are brought into contact with each other on the side opposite to the connecting portion 132 so that the bending is impossible. In the power supply device 1, the bending restriction member 130 is arranged along the wire harness 110 so that the bending restriction member 130 cannot be bent in a desired direction in which the bending of the wire harness 110 is desired to be restricted. Thereby, about the wire harness 110, the curvature can be controlled by making the desired direction into the control direction D16. As a result, when the slide door 50 is opened and closed, the wire harness 110 is disposed in the following preferable position in the vicinity of the vehicle body 60.

  FIG. 7 is a cross-sectional view taken along the line V13-V13 in FIG. 1, showing a state in which the wire harness is disposed at a preferred position in the vicinity of the vehicle body when the sliding door is opened and closed.

  As described above, the portion of the U-shaped wire harness 110 that is substantially U-shaped when the slide door 50 is opened and closed corresponds to the arm on the vehicle body 60 side, and the curve in the regulation direction D16 toward the inside of the vehicle body 60 is curved. It is regulated by the member 130. As shown in FIG. 7, the wire harness 110 whose curvature is regulated in this way is positioned slightly outside the step 61 in the vehicle body 60 together with the corrugated tube 120 and the curvature regulating member 130. Thus, in this embodiment, the wire harness 110 toward the step 61 side inside the vehicle body 60 when the slide door 50 is opened and closed is prevented from being swollen.

  In the present embodiment, in the plurality of member pieces 131 constituting the bending restriction member 130, at least in the middle of the bending restriction member 130, when the bending restriction member 130 is in a substantially straight state, adjacent ones are connected to each other. 132 are in contact with each other on the opposite side.

  In the power feeding device 1, in the wire harness 110, the approach to the step 61 when the sliding door 50 is opened and closed is in the middle. According to the bending restricting member 130 of the present embodiment, the bending in the restricting direction D16 can be suppressed to almost zero for the portion along the middle of the wire harness 110. Almost can be eliminated.

  Further, in the present embodiment, in the bending restriction member 130, the interval between the plurality of member pieces 131 is set to the vehicle body side holding portion 150 in a substantially straight state that is not curved in any of the allowable direction D <b> 13 and the restriction direction D <b> 16. It is set to be different between a part in the vicinity of and other parts. Thereby, the limit state with respect to the curve in the regulation direction D16 in the curve regulation member 130 is different at the above two locations in the arrangement direction of the plurality of member pieces 131. Thereby, the shape when the bending restricting member 130 is bent to each limit state in the restricting direction D16 is not a simple linear shape or arc shape, but is shown in FIG. 1 according to the interval at each location. Shape. Thus, in this embodiment, the shape when the bending restriction member 130 is bent to each limit state in the restriction direction D16 is a desired shape according to the installation state of the wire harness 110 in the power supply device 1 as described above. can do.

  In this way, the shape when bent to the limit state can be set to an arbitrary shape at the design stage depending on how the interval between the plurality of member pieces 131 is set. For example, a desired interval in the design stage according to the shape (in this embodiment, the shape shown in FIG. 1) that the wire harness 110 wants to take when a force that causes bending in the regulation direction D <b> 16 is applied to the wire harness 110. Can be set. Thus, by setting the interval between the member pieces 131 at the design stage, it is possible to obtain a desired shape when curved in the restriction direction D16 to each limit state.

  Further, in the bending restricting member 130 of the present embodiment, the plurality of member pieces 131 and the connecting portion 132 are integrally molded with each other. This eliminates the need for assembling work of the bending restricting member 130, and can reduce the manufacturing cost.

  Further, in the bending restricting member 130 of the present embodiment, each of the plurality of member pieces 131 includes a pair of opposing walls 1311 that face each other with the wire harness 110 interposed therebetween, and a coupling wall that connects the pair of opposing walls 1311. 1312. As a result, each member piece 131 is a member having a substantially C-shaped cross section that intersects the length direction D17 of the wire harness 110. Accordingly, for example, the bending regulating member 130 can be easily placed along the wire harness 110 so that the member pieces 131 having a substantially C-shaped cross-sectional shape are placed on the wire harness 110.

  Here, in the present embodiment, as described with reference to FIG. 1, the wire harness 110 is quickly formed into a U shape at the initial stage of opening the slide door 50. Such a U-shape is formed by urging the wire harness 110 to move away from the slide door 50 and toward the front side of the vehicle 5 in the direction opposite to the opening direction D111. Therefore, in the reference example related to the swinging of the wire harness 110, the coil spring that biases the wire harness 110 so as to be away from the slide door 50 and to face in the direction opposite to the opening direction D111 of the slide door 50 is the door side holding portion 140. Is provided. However, in contrast to this reference example, in the first embodiment according to the present invention, the structure that promotes the swinging of the wire harness 110 at the initial stage of the opening of the slide door 50 as described above does not use a coil spring. It has a structure.

  FIG. 8 is a schematic diagram showing the structure of a reference example that promotes the swing of the wire harness using a coil spring when the sliding door is opened, and the structure of the first embodiment corresponding thereto. FIG. 8A is a schematic diagram illustrating the structure of the door-side holding unit 140 employed in the power supply device 1 of the reference example. FIG. 8B is a schematic diagram showing the structure of the door side holding portion 140 ′ of the first embodiment. In FIG. 8 (B), the same reference numerals as those in FIG. 8 (A) are given to the same components as those of the door side holding portion 140 of the reference example shown in FIG. 8 (A).

  First, as shown in FIG. 8A, the door-side holding portion 140 of the reference example is also shown in FIG. 1 by the fixing portion 142 fixed to the slide door 50 and the fixing portion 142. And a swinging portion 143 that is swingably supported around the door-side swinging shaft 141. The end portion on the slide door 50 side of the corrugated tube 120 that covers the wire harness 110 is fixed to the swing portion 143, so that the slide door 50 side of the wire harness 110 is held by the swing portion 143. A coil spring 144 is provided around the door-side swing shaft 141. By this coil spring 144, the swinging portion 143, that is, the wire harness 110 is urged in the urging direction D12 that moves away from the sliding door 50 and faces the front side of the vehicle 5 in the direction opposite to the opening direction D111. ing. The coil spring 144 urges the wire harness 110 to swing in the urging direction D12.

  On the other hand, the coil spring for biasing as described above is not provided in the door side holding portion 140 ′ of the first embodiment shown in FIG. Instead, a restricting portion 145 that restricts the position of the wire harness 110 around the door-side swing shaft 141 is provided. When the slide door 50 is fully closed, the restricting portion 145 restricts the position of the slide door 50 on the front side in the opening direction D111 around the door-side swing shaft 141 as follows. That is, the restricting portion 145 restricts this position so that the wire harness 110 and the slide door 50 form an acute angle θ that is equal to or greater than a predetermined angle around the door-side swing shaft 141. This position restriction restricts the swing of the wire harness 110 in the swing direction D18 when the slide door 50 is closed in the closing direction D112 at the position where the wire harness 110 and the slide door 50 form the acute angle θ described above. This is done by the part 145 being fastened.

  In the door-side holding portion 140 ′ of the first embodiment, when the slide door 50 is fully closed, the wire harness 110 and the slide door 50 form the acute angle θ around the door-side swing shaft 141, and the wire harness 110 is inclined to some extent with respect to the slide door 50. Thereby, when the slide door 50 is opened, the wire harness 110 quickly swings in the opening direction D19 with respect to the slide door 50, and is bent in a substantially U shape from the vehicle body 60 side to the slide door 50 side. It becomes a shape. In the wire harness 110 having such a shape, along with the restriction by the bending restriction member 130 during the movement of the slide door 50, the linear shape in the portion on the vehicle body 60 side corresponding to one arm of the U shape. Is kept good. As a result, it is possible to further restrict the bending of the wire harness 110 that swells toward the vehicle body 60 while the slide door 50 is moving.

  Further, in the door side holding portion 140 ′ of the first embodiment, the above-described rapid swinging of the wire harness 110 when the slide door 50 is opened is urged by the restriction in the restriction portion 145. For this reason, the biasing spring etc. for swinging the wire harness 110 in this way are unnecessary, and the structure can be simplified.
