Description

[Technical Field]

[0001] The present invention relates to a power supply device. [Background technology]

[0002] Patent Document 1 describes a power supply device that supplies power from a battery to electrical components of a sliding door. The power supply device includes a wire harness that connects the vehicle body and the sliding door, a harness fixture that supports the wire harness when installed in the vehicle body, and a harness protector that supports the wire harness when installed in the sliding door.

[0003] The harness fixture has a spherical rotating member that holds the wire harness and a case that rotatably houses the rotating member. The harness fixture adjusts the position of the wire harness extending toward the sliding door by rotating the rotating member in accordance with the opening and closing operation of the sliding door. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-282879 Summary of the Invention [Problem to be solved by the invention]

[0005] In the power supply device described above, the case includes a base that supports the lower half of the rotating member and a cover that supports the upper half of the rotating member. The base and cover are generally molded from a resin material. Therefore, the portions of the base and cover that support the rotating member are spherical in shape to match the outer shape of the rotating member in order to avoid sink marks during molding. Therefore, the power supply device described above leaves room for improvement in terms of improving the appearance of the cover, which is easily noticeable to users. [Means for solving the problem]

[0006] The means for solving the above problems and their effects will be described below. The power supply device that solves the above problem is a power supply device that is applied to a vehicle that has a body with a door opening and a sliding door that opens and closes the door opening, and includes: a holding portion that holds a wire harness that connects the body and the sliding door; and a housing that houses the holding portion so that it cannot translate and can rotate, and when installed on the vehicle, the housing has a base that supports the holding portion from below and a cover that covers the holding portion from above, and the cover is made of a resin material and has a flat upper wall and a plurality of sliding ribs that extend from the upper wall toward the holding portion and slide against the holding portion.

[0007] In the power supply device, the cover constituting the housing supports the retaining portion so that it cannot translate and can rotate by sliding the retaining portion on a sliding rib extending from the upper wall. Therefore, the power supply device can adjust the position of the wire harness in accordance with the opening and closing of the sliding door. Here, because the upper wall of the cover is flat, when the power supply device is viewed from above, the upper surface of the portion that houses the retaining portion is flat. This allows the power supply device to improve the appearance of the cover, which is easily noticeable to users.

[0008] When the direction in which the wire harness passes through the inside of the housing is defined as the routing direction, it is preferable that the multiple sliding ribs are arranged facing the routing direction, and that the cover includes a connecting rib extending from the upper wall toward the retaining portion and connecting the multiple sliding ribs.

[0009] In the power supply device, the sliding ribs are connected by the connecting rib, which allows the rigidity of the sliding ribs to be increased. It is preferable that a gap is provided between the connecting rib and the retaining portion, and that both end portions of the connecting rib are higher in height from the upper wall in the routing direction than the center portion of the connecting rib.

[0010] The power supply device can ensure the height of the connecting rib while avoiding contact between the connecting rib and the holding portion, thereby further increasing the rigidity of the plurality of sliding ribs. When the direction in which the wire harness passes through the inside of the housing is defined as the routing direction, the plurality of sliding ribs are arranged facing the routing direction, and the cover preferably includes a reinforcing rib extending from the upper wall toward the retaining portion between the plurality of sliding ribs, and a gap is preferably provided between the reinforcing rib and the retaining portion.

[0011] The reinforcing ribs can increase the rigidity of the cover of the power supply device. Since a gap is provided between the reinforcing ribs and the retaining portion, the reinforcing ribs do not slide on the retaining portion. Therefore, unlike sliding ribs, the position of the tip of the reinforcing ribs does not need to be precisely controlled.

[0012] It is preferable that the retaining portion has a protrusion extending radially, and the cover has a regulating rib that contacts the protrusion of the retaining portion when the sliding door is positioned in a fully closed position in which the door opening is fully closed.

[0013] The power supply device can bring the protrusion of the holding portion into contact with the restricting rib of the cover when the sliding door is in the fully closed position, thereby stabilizing the posture of the wire harness held by the holding portion when the sliding door is in the fully closed position.

[0014] It is preferable that the regulating rib has a first contact surface and a second contact surface that contact the protrusion of the retaining portion when the sliding door is positioned in the fully closed position, and that the first contact surface and the second contact surface face in different directions.

[0015] When the sliding door is in the fully closed position, the power supply device can bring the protrusion of the holding part into contact with the first and second contact surfaces facing in different directions. In this case, the first and second contact surfaces come into contact with the protrusion of the holding part from two directions. Therefore, the power supply device can more stabilize the posture of the wire harness held by the holding part when the sliding door is in the fully closed position.

[0016] The regulating rib has a thin plate portion, a thick plate portion that is thicker than the thin plate portion, and a connecting portion that connects the thin plate portion and the thick plate portion and whose thickness gradually increases from the thin plate portion to the thick plate portion, and it is preferable that the thin plate portion includes the first contact surface and the connecting portion includes the second contact surface.

[0017] In the power supply device, the first contact surface and the second contact surface can be provided on the restriction rib by changing the thickness of the restriction rib. [Effects of the Invention]

[0018] The power supply device can improve the appearance of the cover. [Brief explanation of the drawings]

[0020] Hereinafter, an embodiment of a power supply device will be described with reference to the drawings. <Vehicle 10> As shown in FIG. 1, a vehicle 10 includes a vehicle body 20, a sliding door 30, a door actuator 40, a battery 50, and a power supply device 60.

[0021] <Body 20> 1, the vehicle body 20 has a door opening 21 that opens to the side. The door opening 21 has a rectangular shape when the vehicle 10 is viewed from the side. The door opening 21 is an area through which a user passes when getting on or off the vehicle 10.

[0022] <Sliding Door 30> As shown in FIG. 2, the sliding door 30 includes an outer panel 31, an inner panel 32, and a door trim 33.

[0023] The outer panel 31 forms the outer surface of the sliding door 30, and the inner panel 32 forms the inner surface of the sliding door 30. The outer panel 31 and the inner panel 32 are shaped to fit the door opening 21. The outer edges of the outer panel 31 and the inner panel 32 are joined together. A first storage space 34 is provided between the outer panel 31 and the inner panel 32 to store components of the door actuator 40, etc.

[0024] The door trim 33 is a component that constitutes the interior. The door trim 33 is attached to the inner panel 32 with a gap between them. A second accommodation space 35 that accommodates components of the door actuator 40, components of the power supply device 60, etc. is provided between the inner panel 32 and the door trim 33. The second accommodation space 35 is open downward.

[0025] <Door actuator 40> As shown in FIG. 1 , the door actuator 40 has an electric motor 41 that is driven by supply of electric power. Although not shown, the door actuator 40 has a transmission mechanism that transmits the power of the electric motor 41 to the sliding door 30. The electric motor 41 corresponds to an example of an electrical component housed in the first accommodation space 34 or the second accommodation space 35 of the sliding door 30. The door actuator 40 opens and closes the sliding door 30 based on the electric power supplied from the battery 50. As a result, the sliding door 30 is opened and closed between a fully open position where the door opening 21 is fully opened and a fully closed position where the door opening 21 is fully closed.

[0026] In addition to the electric motor 41 of the door actuator 40, the vehicle 10 may also include electrical components accommodated in the first accommodation space 34 or the second accommodation space 35 of the sliding door 30. For example, the vehicle 10 may also include a door lock actuator that drives a door lock device that locks the sliding door 30 in the fully closed position, a window regulator that raises and lowers the window glass of the sliding door 30, or a speaker.

[0027] <Battery 50> The battery 50 is installed, for example, in an engine compartment of the vehicle body 20. The battery 50 is a secondary battery. The battery 50 serves as a power supply source for various electrical components such as the door actuator 40.

[0028] <Power supply device 60> 2, the power supply device 60 includes a wire harness 70, a vehicle body-side support structure 80, and a door-side support structure 90. The power supply device 60 supplies power from a battery 50 to a door actuator 40 provided on the sliding door 30.

[0029] <Wire harness 70> As shown in FIGS. 1 and 2 , the wire harness 70 includes an electric wire 71 and a corrugated tube 72 that covers the electric wire 71. A first end of the electric wire 71 is connected to the battery 50, and a second end of the electric wire 71 is connected to the door actuator 40. The number of electric wires 71 may be determined according to the number of electrical components included in the sliding door 30. The corrugated tube 72 is preferably bellows-shaped so as to be easily bent when a load is applied. In this embodiment, the corrugated tube 72 covers a portion of the electric wire 71 that connects the vehicle body support structure 80 and the door support structure 90. A first end of the corrugated tube 72 is supported by the vehicle body support structure 80, and a second end of the corrugated tube 72 is supported by the door support structure 90.

[0030] <Vehicle body side support structure 80> As shown in Fig. 3, the vehicle body support structure 80 includes a holding portion 110 that holds the corrugated tube 72, and a housing 120 that accommodates the holding portion 110. As shown in Fig. 1, the vehicle body support structure 80 is installed on the floor or step of the vehicle body 20, near the rear end of the door opening 21. In other words, the vehicle body support structure 80 is installed in a position that can be seen by users getting on and off the vehicle 10 through the door opening 21.

[0031] The configuration of the holding portion 110 will be described. As shown in FIG. 3 , the holding portion 110 is spherical and has a cylindrical through-hole. The holding portion 110 has a first holding portion 111 and a second holding portion 112 each having a hemispherical shape. The first holding portion 111 and the second holding portion 112 each include a protrusion 113 extending radially. The protrusion 113 is cylindrical. The first holding portion 111 and the second holding portion 112 are integrated by sandwiching the first end of the corrugated tube 72. Preferably, the first holding portion 111 and the second holding portion 112 are integrated by a so-called snap fit. When the holding portion 110 is holding the corrugated tube 72, the protrusion 113 of the first holding portion 111 and the protrusion 113 of the second holding portion 112 extend in opposite directions. The two protrusions 113 extend in a direction intersecting the longitudinal direction of the corrugated tube 72.

[0032] The configuration of the housing 120 will be described. The housing 120 has a base 200 that supports the holding portion 110 from below, and a cover 300 that covers the holding portion 110 from above. The housing 120 accommodates the wire harness 70 and the holding portion 110. At this time, the housing 120 supports the holding portion 110 so that it cannot translate and can rotate. In the following description, the direction in which the wire harness 70 passing through the housing 120 extends is referred to as the "wiring direction," and the direction intersecting both the vertical direction of the vehicle 10 and the wiring direction is referred to as the "width direction." The wire harness 70 passes through the housing 120 while changing direction inside the housing 120. Therefore, the wiring direction and width direction vary depending on the part of the housing 120. However, the wiring direction and width direction referred to here are directions perpendicular to the vertical direction.

[0033] The configuration of the base 200 will be described. 3, the base 200 constitutes the lower part of the housing 120. Because the base 200 is a molded product made of a resin material such as a thermoplastic resin, the thickness of each part of the base 200 is determined in consideration of moldability. In other words, the thickness of each part of the base 200 is set to a thickness that will not cause sink marks during molding.

[0034] The base 200 includes a first support portion 210 that supports the wire harness 70 extending from the battery 50, a first guide portion 220 that guides the wire harness 70 toward the sliding door 30, and a plurality of first engagement portions 230 that engage with the cover 300. The base 200 also includes a first accommodating portion 240 that rotatably accommodates the holding portion 110. The first accommodating portion 240 will be described in detail below.

[0035] As shown in FIGS. 4 and 5, the first accommodating portion 240 has a bottom wall 241, two sliding walls 242, a restricting wall 243, a first reinforcing wall 244, and a second reinforcing wall 245. As shown in Fig. 5, the bottom wall 241 has a spherical shape. In other words, the bottom wall 241 is curved so that the center is positioned lower than both ends in both the wiring direction and the width direction. As shown in Fig. 4, the bottom wall 241 has a rectangular shape in a plan view from above, with the wiring direction as the short side and the width direction as the long side. The bottom wall 241 has two drainage holes 246 positioned on either side of the restriction wall 243. The two drainage holes 246 are holes for draining water that has entered the bottom wall 241.

[0036] As shown in FIGS. 4 and 5 , the two sliding walls 242 extend upward from both ends of the bottom wall 241 in the routing direction. The two sliding walls 242 are point-symmetric when viewed from above. The two sliding walls 242 have a constant height from the bottom wall 241 in the width direction. However, because the bottom wall 241 is spherical, the tips of the two sliding walls 242 are arc-shaped when viewed from the routing direction. The tips of the two sliding walls 242 are portions that slide against the holding portion 110. Therefore, the tip surfaces of the sliding walls 242 form part of a sphere that is slightly larger than the diameter of the holding portion 110. In this embodiment, the widths of the two sliding walls 242 are different on both sides of the restricting wall 243 in the width direction. In other embodiments, the widths of the two sliding walls 242 may be equal on both sides in the width direction.

[0037] The restricting wall 243 extends upward from the lowest part of the bottom wall 241 in the width direction. The restricting wall 243 connects the two sliding walls 242 in the wiring direction. The restricting wall 243 has a constant height from the bottom wall 241. However, because the bottom wall 241 is spherical, the tip of the restricting wall 243 has an arc shape when viewed in the width direction. Like the two sliding walls 242, the tip of the restricting wall 243 is a part that slides against the holding portion 110. Therefore, the tip surface of the restricting wall 243 forms part of a sphere that is slightly larger than the diameter of the holding portion 110. In addition, the tip surface of the restricting wall 243 is continuous with the tip surfaces of the two sliding walls 242. Two recesses are located between the two sliding walls 242 and the restricting wall 243. In the following description, the two recesses defined by the two sliding walls 242 and the restricting wall 243 will be referred to as accommodation recesses 247.

[0038] The first reinforcing wall 244 extends downward from the periphery of the bottom wall 241. In other words, the first reinforcing wall 244 extends in the opposite direction to the sliding wall 242 and the restricting wall 243. The first reinforcing wall 244 has a frame shape when viewed from below. The second reinforcing wall 245 extends downward from the lowest part of the bottom wall 241. In other words, the second reinforcing wall 245 extends in the opposite direction to the restricting wall 243. The second reinforcing wall 245 is connected to the first reinforcing wall 244 in the routing direction.

[0039] The structure of the cover 300 will be described. 3, cover 300 constitutes the upper part of housing 120. Because cover 300 is a molded product made of a resin material such as a thermoplastic resin, the thickness of each part of cover 300 is determined in consideration of moldability. In other words, the thickness of each part of cover 300 is set to a thickness that will not cause sink marks during molding.

[0040] 6, the cover 300 includes a second support portion 310 that supports the wire harness 70 extending from the battery 50, a second guide portion 320 that guides the wire harness 70 toward the sliding door 30, and a plurality of second engagement portions 330 that engage with the base 200. The cover 300 also includes a second accommodating portion 340 that rotatably accommodates the holding portion 110. The second accommodating portion 340 will be described in detail below.

[0041] 7 and 8, the second accommodating section 340 has an upper wall 351, two side walls 352, two sliding ribs 360, and a restricting rib 370. The second accommodating section 340 also has two inner connecting ribs 381, four inner reinforcing ribs 391, two outer reinforcing ribs 392, four outer connecting ribs 382, ​​and four outer connecting ribs 383. The number of each type of rib in the second accommodating section 340 can be changed as appropriate.

[0042] Unlike the bottom wall 241 of the base 200, the top wall 351 has a flat plate shape. Therefore, both the top surface and the bottom surface of the top wall 351 are flat. When viewed from above, the top wall 351 has a rectangular shape with the wiring direction as the short side direction and the width direction as the long side direction. The two side walls 352 extend downward from both ends of the top wall 351 in the width direction. Like the top wall 351, the side walls 352 also have a flat plate shape.

[0043] The two sliding ribs 360 extend downward from the upper wall 351 with a gap between them in the wiring direction. Both ends of the two sliding ribs 360 in the width direction are connected to the two side walls 352, respectively. The two sliding ribs 360 are plate-shaped with the wiring direction as the plate thickness direction. The two sliding ribs 360 face each other in the wiring direction. The two sliding ribs 360 are parts that slide with the holding portion 110. Therefore, the heights of the two sliding ribs 360 from the upper wall 351 gradually increase from the center to both ends in the width direction. More specifically, the tip surface of the sliding rib 360 forms part of a sphere that is slightly larger than the diameter of the holding portion 110.

[0044] The restricting rib 370 extends downward from the center of the upper wall 351 in the width direction. The restricting rib 370 connects the two sliding ribs 360 in the installation direction. The restricting rib 370 is plate-shaped with its thickness in the width direction. The restricting rib 370 is a portion that slides against the holding portion 110. Therefore, the height of the restricting rib 370 from the upper wall 351 gradually increases from the center toward both ends in the installation direction. More specifically, the tip surface of the restricting rib 370 forms part of a sphere that is slightly larger than the diameter of the holding portion 110. Furthermore, the tip surface of the restricting rib 370 is continuous with the tip surfaces of the two sliding ribs 360.

[0045] The thickness of the restricting rib 370 varies between the two sliding ribs 360. Specifically, the restricting rib 370 has, between the two sliding ribs 360, a thin plate portion 371, a connecting portion 372 connected to the thin plate portion 371, and a thick plate portion 373 connected to the connecting portion 372. The plate thickness of the thin plate portion 371 is thinner than the plate thickness of the thick plate portion 373. The plate thickness of the connecting portion 372 gradually increases from the connecting portion with the thin plate portion 371 toward the connecting portion with the thick plate portion 373. The thin plate portion 371 has a first contact surface 371a along the wiring direction, the connecting portion 372 has a second contact surface 372a intersecting the wiring direction, and the thick plate portion 373 has a third contact surface 373a along the wiring direction. The first contact surface 371a, the second contact surface 372a, and the third contact surface 373a constitute one of two side surfaces that intersect with the width direction of the sliding rib 360. In the following description, in the second accommodating portion 340, two areas defined by the upper wall 351, the two side walls 352, the two sliding ribs 360, and the restriction rib 370 will be referred to as inner defined areas 341.

[0046] Two inner connecting ribs 381 are provided in each of the two inner compartment regions 341. The inner connecting rib 381 located in one of the inner compartment regions 341 extends downward from the upper wall 351 between the two sliding ribs 360. The inner connecting rib 381 connects the two sliding ribs 360 in the installation direction. The inner connecting rib 381 is plate-shaped with its thickness direction in the width direction. The height of the inner connecting rib 381 from the upper wall 351 gradually increases from the center toward both ends in the installation direction. In other words, the tip surface of the inner connecting rib 381 has an arc shape when viewed in the width direction. As a result, both ends of the inner connecting rib 381 in the installation direction are higher from the upper wall 351 than the center of the inner connecting rib 381 in the installation direction. However, the inner connecting rib 381 is lower in height from the upper wall 351 than the portions of the two sliding ribs 360 adjacent to the inner connecting rib 381. The inner connecting rib 381 is an example of a "connecting rib."

[0047] The four inner reinforcement ribs 391 are provided two per each of the two inner compartment regions 341. The two inner reinforcement ribs 391 located in one of the inner compartment regions 341 extend downward from the upper wall 351 between the two sliding ribs 360. The two inner reinforcement ribs 391 extend parallel to the two sliding ribs 360 with a gap in the routing direction. The inner reinforcement ribs 391 are connected to the side walls 352 in the width direction but are not connected to the restricting rib 370. The two inner reinforcement ribs 391 are also connected to the inner connecting ribs 381. That is, the two inner reinforcement ribs 391 are connected to the two sliding ribs 360 via the inner connecting ribs 381. The inner reinforcement rib 391 has a plate-like shape with the routing direction as the plate thickness direction. In the width direction, the inner reinforcing rib 391 increases in height from the upper wall 351 as it approaches the side wall 352, and decreases in height from the upper wall 351 as it approaches the restriction rib 370. In other words, the tip surface of the inner reinforcing rib 391 forms an arc shape when viewed in the width direction. The inner reinforcing rib 391 corresponds to an example of a "reinforcing rib."

[0048] Two outer reinforcement ribs 392 are provided, one on each side of the two sliding ribs 360 in the routing direction. The two outer reinforcement ribs 392 extend downward from the upper wall 351. The two outer reinforcement ribs 392 extend parallel to the adjacent sliding ribs 360. Both widthwise ends of the two outer reinforcement ribs 392 are connected to the two side walls 352, respectively. Furthermore, the widthwise central portions of the two outer reinforcement ribs 392 are connected to the restricting rib 370. That is, the two outer reinforcement ribs 392 are connected to the two sliding ribs 360 via the restricting rib 370. The routing direction of the outer reinforcement rib 392 is the plate thickness direction. The outer reinforcement rib 392 has a plate shape similar to that of the sliding rib 360. That is, the height of the outer reinforcement rib 392 from the upper wall 351 gradually increases from the widthwise central portion toward both ends. In the following description, the four regions of the second accommodating portion 340 defined by the upper wall 351, the side wall 352, and the adjacent sliding ribs 360 and outer reinforcing ribs 392 are referred to as outer defined regions 342.

[0049] Four outer connecting ribs 382 are provided in each of the four outer compartment regions 342, and four outer connecting ribs 383 are provided in each of the four outer compartment regions 342. In each outer compartment region 342, the outer connecting ribs 382, ​​383 extend downward from the upper wall 351. The outer connecting ribs 382, ​​383 are spaced apart in the width direction. The outer connecting rib 382 is located between the restricting rib 370 and the outer connecting rib 383, and the outer connecting rib 383 is located between the side wall 352 and the outer connecting rib 382. The outer connecting ribs 382, ​​383 connect adjacent sliding ribs 360 and outer reinforcing ribs 392. The width direction of the outer connecting ribs 382, ​​383 is the plate thickness direction. The outer connecting rib 382 is located lower on the upper wall 351 than the outer connecting rib 383.

[0050] The engagement relationship between the holding portion 110 and the base 200 and cover 300 that constitute the housing 120 will now be described. 3 and 9, the base 200 supports the wire harness 70 and the holding portion 110 from below. Specifically, the first support portion 210 and the first guide portion 220 of the base 200 support the wire harness 70 from below, and the first accommodating portion 240 of the base 200 supports the holding portion 110 from below.

[0051] Meanwhile, the cover 300 covers the base 200 from above. More specifically, the second support portion 310 of the cover 300 covers the first support portion 210 of the base 200, and the second guide portion 320 of the cover 300 covers the first guide portion 220 of the base 200. As shown in FIG. 2 , the second support portion 310 covers the first support portion 210, thereby forming an inlet 121 for guiding the wire harness 70 into the housing 120. Meanwhile, the second guide portion 320 covers the first guide portion 220, thereby forming an outlet 122 for guiding the wire harness 70 into the housing 120. Furthermore, the second accommodating portion 340 of the cover 300 covers the first accommodating portion 240 of the base 200 together with the holding portion 110. Furthermore, the second engaging portions 330 of the cover 300 engage with the first engaging portions 230 of the base 200, thereby integrating the cover 300 and the base 200. At this time, the first engaging portion 230 and the second engaging portion 330 are locked together by a so-called snap fit.

[0052] 10 to 12 , when the holding portion 110 is housed in the first housing portion 240 of the base 200, the bottom wall 241 of the base 200 is located below the holding portion 110. Therefore, it can be said that the sliding wall 242 and the restricting wall 243 of the base 200 extend toward the holding portion 110. At this time, the leading ends of the sliding wall 242 and the restricting wall 243 contact the holding portion 110. On the other hand, when the holding portion 110 is housed in the second housing portion 340 of the cover 300, the top wall 351 of the cover 300 is located above the holding portion 110. Therefore, it can be said that the various ribs of the second housing portion 340 of the cover 300 extend toward the holding portion 110. At this time, the leading ends of the sliding rib 360 and the restricting rib 370 of the cover 300 contact the holding portion 110.

[0053] In this way, the two sliding walls 242 sandwich the lower half of the holding portion 110 in the width direction and the routing direction. Meanwhile, the two sliding ribs 360 sandwich the upper half of the holding portion 110 in the width direction and the routing direction. Furthermore, the two sliding walls 242 and the restricting wall 243 of the base 200 and the two sliding ribs 360 and the restricting rib 370 of the cover 300 sandwich the holding portion 110 in the up-down direction.

[0054] As a result, the holding portion 110 is rotatable but not translatable relative to the base 200 and the cover 300. Specifically, the holding portion 110 is permitted to rotate about three axes: an axis extending in the routing direction, an axis extending in the width direction, and an axis extending in the up-down direction. When the holding portion 110 rotates, the holding portion 110 slides on the sliding wall 242 and the restricting wall 243 of the base 200 and the sliding rib 360 and the restricting rib 370 of the cover 300. On the other hand, displacement of the holding portion 110 in three directions: the routing direction, the width direction, and the up-down direction is restricted.

[0055] Here, non-translatable does not mean that the holding portion 110 cannot translate at all relative to the base 200 and the cover 300. The holding portion 110 may be slightly translatable relative to the base 200 and the cover 300, for example, due to gaps that occur between the holding portion 110 and the base 200 and the cover 300 due to manufacturing errors or the like. In this regard, due to manufacturing errors or the like, there may be small gaps between the holding portion 110 and the tip ends of the sliding wall 242 and the restricting wall 243, or there may be small gaps between the holding portion 110 and the tip ends of the sliding rib 360 and the restricting rib 370, and the holding portion 110.

[0056] 10 to 12, there are gaps between the inner connecting rib 381, the inner reinforcing rib 391, and the outer reinforcing rib 392 of the cover 300 and the retaining part 110. Although not shown in FIGS. 10 to 12, the same applies to the outer connecting ribs 382, ​​383 of the cover 300. Therefore, the inner connecting rib 381, the outer connecting ribs 382, ​​383, the inner reinforcing rib 391, and the outer reinforcing rib 392 of the cover 300 are ribs that do not slide on the retaining part 110.

[0057] 11 and 12 , when the base 200 and the cover 300 are integrated, the two accommodating recesses 247 of the base 200 and the two inner compartment areas 341 of the cover 300 are connected to each other. Although not shown in FIGS. 11 and 12 , one protrusion 113 of the holding portion 110 is accommodated in the accommodating recess 247 or the inner compartment area 341 on one side, and the other protrusion 113 of the holding portion 110 is accommodated in the accommodating recess 247 or the inner compartment area 341 on the other side. Depending on the posture of the holding portion 110, one protrusion 113 of the holding portion 110 may be positioned so as to straddle the accommodating recess 247 and the inner compartment area 341 on one side, and the other protrusion 113 of the holding portion 110 may be positioned so as to straddle the accommodating recess 247 or the inner compartment area 341 on the other side. When the holding part 110 rotates, the protrusions 113 of the holding part 110 come into contact with the sliding walls 242 and the restricting walls 243 of the base 200, or with the sliding ribs 360 and the restricting ribs 370 of the cover 300. In this case, the rotation of the holding part 110 is restricted. In other words, the sliding walls 242 and the restricting walls 243 of the base 200 and the sliding ribs 360 and the restricting ribs 370 of the cover 300 are configured to rotatably support the holding part 110, and also to restrict the rotation range of the holding part 110.

[0058] <Door side support structure 90> As shown in FIG. 2 , the door-side support structure 90 has a fixed portion 91 fixed to the inner panel 32 of the sliding door 30 and a support arm 92 rotatably supported by the fixed portion 91. The fixed portion 91 supports the electric wire 71 extending from the second end of the corrugated tube 72, and the support arm 92 supports the second end of the corrugated tube 72. When the wire harness 70 has multiple electric wires 71, the multiple electric wires 71 are bundled within the corrugated tube 72 up to the door-side support structure 90 and branch out from the door-side support structure 90. The door-side support structure 90 adjusts the rotation angle of the support arm 92 in accordance with the opening and closing operation of the sliding door 30, thereby preventing the wire harness 70 from sagging below the sliding door 30. For example, when bending occurs in the wire harness 70, the support arm 92 rotates in a direction to lift the wire harness 70.

[0059] <Operation of this embodiment> 1, when the sliding door 30 is in the fully closed position, the support arm 92 of the door-side support structure 90 is located in front of the outlet 122 of the vehicle-body-side support structure 80. The support arm 92 of the door-side support structure 90 and the outlet 122 of the vehicle-body-side support structure 80 are located so as to substantially overlap in the width direction. Therefore, as shown by the solid line in FIG. 9, the wire harness 70 extends forward from the vehicle-body-side support structure 80.

[0060] 14, when the sliding door 30 is located in the fully closed position, the protrusion 113 of the holding portion 110 of the vehicle body support structure 80 comes into contact with the restricting wall 243 of the base 200. The protrusion 113 of the holding portion 110 also comes into contact with the restricting rib 370 of the cover 300. Here, the protrusion 113 of the holding portion 110 comes into contact with both the first contact surface 371a and the second contact surface 372a of the restricting rib 370 of the cover 300. Therefore, when the sliding door 30 is located in the fully closed position, the holding portion 110 is less likely to rotate unintentionally even if vibrations act on the vehicle 10. In other words, the first end of the corrugated tube 72 is less likely to be displaced unintentionally.

[0061] When the sliding door 30 is opened from the fully closed position, the positional relationship between the vehicle body 20 and the sliding door 30 in the width direction changes, and the positional relationship between the vehicle body 20 and the sliding door 30 in the front-rear direction also changes. Specifically, when the sliding door 30 is opened from the fully closed position, the sliding door 30 moves in the width direction away from the vehicle body-side support structure 80. Furthermore, when the sliding door 30 is opened from the fully closed position, the sliding door 30 moves rearward relative to the vehicle body-side support structure 80 in the front-rear direction. Furthermore, the holding portion 110 of the vehicle body-side support structure 80 rotates about an axis extending in the up-down direction, causing the corrugated tube 72 to swing as shown by the outline arrow in FIG. 9. At this time, the holding portion 110 of the vehicle body-side support structure 80 rotates about an axis extending in the wiring direction, causing the corrugated tube 72 to rotate as shown by the solid arrow in FIG. 9.

[0062] As shown in Fig. 13 , when the sliding door 30 is in the fully open position, the support arm 92 of the vehicle body-side support structure 80 is located rearward of the outlet 122 of the door-side support structure 90. Furthermore, the support arm 92 of the door-side support structure 90 is located outward in the width direction from the outlet 122 of the door-side support structure 90. Therefore, as shown in Fig. 13 , the wire harness 70 extends upward while extending outward in the width direction from the vehicle body-side support structure 80. At this time, the support arm 92 pulls up the second end of the wire harness 70 so as to prevent the wire harness 70 from bending.

[0063] 15, when the sliding door 30 is in the fully open position, the protrusion 113 of the holding portion 110 may come into contact with the restricting wall 243 of the base 200 in the vehicle body side support structure 80. Also, the protrusion 113 of the holding portion 110 comes into contact with the restricting rib 370 of the cover 300. Therefore, when the sliding door 30 is in the fully open position, the holding portion 110 is less likely to rotate unintentionally.

[0064] In this way, the power supply device 60 changes the support mode of the wire harness 70 when the position of the sliding door 30 changes due to the opening and closing operation of the sliding door 30. In this way, the power supply device 60 can prevent a load from being applied to the wire harness 70 and prevent the wire harness 70 from sagging.

[0065] <Effects of this embodiment> (1) In the power supply device 60, the cover 300 constituting the housing 120 supports the holding portion 110 so as to be non-translatable and rotatable by sliding the holding portion 110 on a sliding rib 360 extending from the upper wall 351. Therefore, the power supply device 60 can adjust the position of the wire harness 70 in accordance with the opening and closing of the sliding door 30. Here, the upper wall 351 of the cover 300 is flat. Therefore, as shown in FIGS. 2 and 13, when the vehicle body support structure 80 is viewed from above, the outer shape of the portion that houses the holding portion 110 can be configured to be flat. This allows the power supply device 60 to have a better appearance.

[0066] 5, when the first storage section 240 is viewed from below, the bottom surface of the bottom wall 241 is not flat. However, the bottom surface of the bottom wall 241 is a portion that comes into contact with the floor or step of the vehicle body 20. Therefore, the bottom surface of the bottom wall 241 is not a portion that is visible to a user getting in and out of the vehicle 10 through the door opening 21.

[0067] (2) In the second housing portion 340 of the cover 300, the two sliding ribs 360 are connected by the inner connecting rib 381. Furthermore, the sliding ribs 360 are connected to adjacent outer reinforcing ribs 392 by the outer connecting ribs 382, ​​383. Therefore, the cover 300 can increase the rigidity of the two sliding ribs 360. Furthermore, the cover 300 can increase the rigidity of the second housing portion 340.

[0068] (3) In the second accommodating portion 340 of the cover 300, both end portions of the inner connecting rib 381 are higher from the upper wall 351 than the center portion of the inner connecting rib 381. Therefore, the power supply device 60 can ensure the height of the inner connecting rib 381 while avoiding contact between the inner connecting rib 381 and the holder 110. This allows the cover 300 to further increase the rigidity of the second accommodating portion 340. Because a gap is provided between the inner connecting rib 381 and the holder 110, the inner connecting rib 381 is a portion that does not slide with the holder 110. Therefore, unlike the sliding rib 360, the position of the tip of the inner connecting rib 381 does not need to be precisely controlled.

[0069] (4) The second housing portion 340 of the cover 300 has an inner reinforcing rib 391 extending from the upper wall 351 on the inner side of the two sliding ribs 360. The second housing portion 340 of the cover 300 also has an outer reinforcing rib 392 extending from the upper wall 351 on the outer side of the two sliding ribs 360. This allows the cover 300 to increase the rigidity of the second housing portion 340. Gaps are provided between these reinforcing ribs 391, 392 and the retaining portion 110, and the reinforcing ribs 391, 392 are not in sliding contact with the retaining portion 110. Therefore, unlike the sliding rib 360, the positions of the tips of the reinforcing ribs 391, 392 do not need to be precisely controlled.

[0070] (5) When the sliding door 30 is in the fully closed position, the power supply device 60 can bring the protrusion 113 of the holding portion 110 into contact with the restricting rib 370 of the cover 300. Therefore, when the sliding door 30 is in the fully closed position, the power supply device 60 can stabilize the posture of the wire harness 70 held by the holding portion 110.

[0071] (6) When the sliding door 30 is located at the fully closed position, the power supply device 60 can bring the protrusion 113 of the holding portion 110 into contact with the first contact surface 371a and the second contact surface 372a, which face in different directions. In this case, the first contact surface 371a and the second contact surface 372a come into contact with the protrusion 113 of the holding portion 110 from two directions. Therefore, the power supply device 60 can further stabilize the posture of the wire harness 70 held by the holding portion 110 when the sliding door 30 is located at the fully closed position.

[0072] In the restricting rib 370, the thin plate portion 371 and the thick plate portion 373 are connected by a connecting portion 372 having a second contact surface 372a. Therefore, when the sliding door 30 is operated to close, the protrusion 113 of the holding portion 110 is easily guided to a position where it contacts both the first contact surface 371a and the second contact surface 372a.

[0073] (7) In the power supply device 60, the thickness of the restriction rib 370 is changed, so that the restriction rib 370 can be provided with the first contact surface 371a and the second contact surface 372a. (8) As shown in Fig. 8, in the second accommodating portion 340 of the cover 300, the direction in which the various ribs extend relative to the upper wall 351 is the thickness direction of the upper wall 351. Therefore, the second accommodating portion 340 of the cover 300 has a shape that can be molded using two molds that are separated in the thickness direction of the upper wall 351. In other words, the second accommodating portion 340 of the cover 300 has a shape that is easy to mold.

[0074] 10 to 12, the contact points of the cover 300 with the holding part 110 are limited to the sliding rib 360 and the restricting rib 370. However, the sliding rib 360 and the restricting rib 370 are reinforced by the inner connecting rib 381, the outer connecting ribs 382 and 383, the inner reinforcing rib 391, and the outer reinforcing rib 392, which do not contact the holding part 110. Therefore, the power supply device 60 can ensure the strength of the sliding rib 360 and the restricting rib 370 while reducing the contact area between the cover 300 and the holding part 110.

[0075] <Example of change> This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility.

[0076] The number of protrusions 113 on the holding portion 110 can be changed as appropriate. For example, the number of protrusions 113 may be "0" or may be three or more. The holding portion 110 may be ellipsoidal in shape as long as it is non-translatable and rotatable relative to the housing 120.

[0077] The housing 120 only needs to accommodate the holding portion 110 so that the holding portion 110 can rotate about at least two axes extending in both the vertical and width directions. In the base 200, the first accommodating portion 240 does not have to include the restricting wall 243, and in the cover 300, the second accommodating portion 340 does not have to include the restricting rib 370.

[0078] In the base 200, the restricting wall 243 of the first accommodating portion 240 may include a thin plate portion 371, a connecting portion 372, and a thick plate portion 373, similar to the restricting rib 370 of the second accommodating portion 340 in the cover 300. This modification can further stabilize the posture of the wire harness 70 when the sliding door 30 is in the fully closed position.

[0079] In the cover 300, the number of sliding ribs 360 provided in the second housing portion 340 can be changed as appropriate. For example, if the second housing portion 340 has three or more sliding ribs 360, the number of connecting ribs 381-383 and reinforcing ribs 391, 392 may be fewer than in the above embodiment. For example, the number of connecting ribs 381-383 and reinforcing ribs 391, 392 may be zero.

[0080] In the cover 300, the sliding rib 360 of the second housing portion 340 does not have to be flat as long as the tip surface forms a spherical surface corresponding to the outer diameter of the holding portion 110. For example, the sliding rib 360 may be prismatic or cylindrical, or may have an L-shaped cross section perpendicular to the extension direction. The sliding rib 360 may also be configured to gradually taper from the base end to the tip.

[0081] In the cover 300, the restriction rib 370 may have a constant thickness in the wiring direction. In other words, the restriction rib 370 does not have to include the connection portion 372 and the thick portion 373.

[0082] In the cover 300, the restricting rib 370 may have a receiving portion that engages with the protrusion 113 of the holding portion 110 when the sliding door 30 is in the fully closed position. In this case, it is preferable that the shape of the receiving portion corresponds to the outer shape of the protrusion 113 of the holding portion 110.

[0083] The power supply device 60 may be configured such that a configuration equivalent to the vehicle body-side support structure 80 is installed on the sliding door 30 and a configuration equivalent to the door-side support structure 90 is installed on the vehicle body 20 .
