Description

Technical Field

[0001] The present invention relates to a wire harness.

Background Art

[0002] In an automobile equipped with a sliding door, electrical components on the vehicle body side and electrical components on the sliding door side are electrically connected by a harness device (see Patent Documents 1 to 3). For example, the harness device described in Patent Document 1 includes a harness main body that is routed between the vehicle body and the sliding door, a door-side bracket (support member) that is attached to one end of the harness main body and fixed to the sliding door, and a body-side bracket (holding member) that is attached to the other end of the harness main body and fixed to the vehicle body.

[0003] A rotating member (rotating member) is rotatably attached to the support frame of the door-side bracket. The rotating member is attached so that it can rotate in a horizontal plane when the door-side bracket is attached to the sliding door in a vertically standing posture.

[0004] The door-side end of the harness main body attached to the door-side bracket is drawn out from above the rotation center (rotation axis) of this rotating member, and the vehicle body-side end of the harness main body is led out so as to be swingable in a predetermined rotation angle direction from the connection port of the rotating member. Therefore, when the door-side bracket is attached to the sliding door in a vertically standing posture, the vehicle body-side end of the harness main body attached to the door-side bracket is connected to the door-side bracket so as to extend in the horizontal direction, and the direction in the horizontal plane can be arbitrarily changed.

[0005] Therefore, when the sliding door is opened and closed, the harness main body is bent as the sliding door is opened and closed. Then, due to the bending of this harness main body, the rotating member is rotated with respect to the support frame of the door-side bracket.

[0007] Incidentally, depending on the layout of electrical components in a sliding door, the door-side end of the harness body attached to the support member (door-side bracket) may not be drawn out from above or below along the pivot axis of the rotating member. In this case, the door-side end of the harness body extends radially outward from the pivot axis of the rotating member and is drawn out from the lead-out position of the support member which is radially offset from the pivot axis.

[0008] Therefore, the support side wall portion around the pivot axis of the support member and the rotation side wall portion around the pivot axis of the rotation member are provided with a support side opening and a rotation side opening, respectively, to prevent interference from the bent harness body when the rotation member rotates. Therefore, when the sliding door was fully closed, the harness body, which was extended in a straight line, was visible from both the support-side opening and the rotation-side opening, resulting in an unsightly appearance.

[0009] This invention has been made in view of the circumstances described above, and its purpose is to provide an aesthetically pleasing wire harness that is routed from the vehicle body to the sliding door. [Means for solving the problem]

[0010] To achieve the aforementioned objectives, the wire harness according to the present invention has the following features. The harness itself is routed from the vehicle body to the sliding door, The door-side end of the inserted harness body is led out from the support member side outlet and fixed to the sliding door by a support member, In order to lead out the vehicle body side end of the harness body from the rotating member side outlet in a direction that can pivot freely in a predetermined angle, a rotating member is attached to the support member so as to be rotatable about a pivot axis, In order to prevent the harness body from interfering during rotation, a support-side opening and a rotation-side opening are provided in the support side wall portion around the rotation axis of the support member and the rotation side wall portion around the rotation axis of the rotation member, respectively. To cover the harness body exposed from the support-side opening and the rotation-side opening, a shielding member is provided between the support member and the rotation member, which expands and contracts in accordance with the rotation of the rotation member, A wire harness equipped with [features / equipment].

Mode for Carrying Out the Invention

[0014] Specific embodiments of the present invention will be described below with reference to the respective drawings. (First Embodiment) Figure 1 is a perspective view of the wire harness 1 according to the first embodiment of the present invention when the sliding door is fully closed. Figure 2 is a perspective view of the wire harness 1 shown in Figure 1 when the sliding door is fully open. Figure 3 is an exploded perspective view of the wire harness 1 shown in Figure 1. Figure 4 is a perspective view showing the wire harness 1 shown in Figure 3 during assembly. Figure 5 is a perspective view of the main part illustrating the operation of the shielding member 60 shown in Figure 3 when the sliding door is fully closed.

[0015] For the sake of clarity, the following definitions will be used to explain the "front-to-back direction," "left-to-right direction," and "up-down direction," as shown in Figures 1 to 3. These "front-to-back direction," "left-to-right direction," and "up-down direction" are orthogonal to each other and correspond to the direction of the vehicle body when the part is mounted on it.

[0016] The wire harness 1 according to the first embodiment of the present invention is for configuring a harness device that electrically connects electrical components on the vehicle body side and electrical components on the sliding door side (neither of which are shown).

[0017] The harness device comprises a harness body 10 routed between the vehicle body (not shown) and the right-side sliding door; a door-side protector 20 as a support member attached to one end of the harness body 10 and fixed to the sliding door; a door-side rotor 50 as a rotating member rotatably mounted to the door-side protector 20 around a pivot axis Z; and a body-side bracket (not shown) as a retaining member attached to the other end of the harness body 10 and fixed to the vehicle body.

[0018] In other words, as shown in Figures 1 to 3, the wire harness 1 according to this first embodiment comprises a harness body 10, a door-side protector 20 through which the door-side end of the inserted harness body 10 is led out from a support member-side outlet 24 and fixed to the sliding door, and a door-side rotor 50 that is rotatably mounted to the door-side protector 20 around a pivot axis Z extending in the vertical direction, in order to lead out the vehicle body-side end of the harness body 10 from a pivot member-side outlet 44 so as to be able to pivot in a predetermined angular direction.

[0019] The harness body 10 is composed of, for example, a bundle of wires 13 and a corrugated tube 11 that surrounds it. The harness body 10 may also include a flexible member to prevent it from sagging downwards due to its own weight.

[0020] As shown in Figures 3 and 4, the synthetic resin door-side protector 20 comprises a protector body 21 fixed to the sliding door and a protector cover 31 that covers the upper open portion of the protector body 21.

[0021] The protector body 21 has side wall portions 23a that face each other on either side of the wire bundle 13. The side wall portions 23a rise from both sides along the longitudinal direction of the bottom plate portion 22 which is arranged along the wire bundle 13. That is, the cross-sectional shape of the protector body 21 perpendicular to the longitudinal direction is an open U shape at the top.

[0022] On the upper surface of the rear portion of the bottom plate 22, which extends horizontally along the front-rear direction, a support hole 26 is formed for mounting the door-side rotor 50 so that it can rotate around a pivot axis Z. Furthermore, on the outer circumference of the circular support hole 26, an engagement recess 27 is formed in a fan shape when viewed from above, which engages with an engagement projection 47 of the door-side rotor 50 (described later) to restrict the rotation range of the door-side rotor 50.

[0023] Furthermore, in the rear portion of the protector body 21, a support side opening 25 is formed in the support side wall portion 23b around the pivot axis Z to which the rear ends of both side wall portions 23a are connected, in order to prevent interference from the bundle of electric wires 13 attached to the door side rotor 50 when it rotates.

[0024] Furthermore, the front portion of the bottom plate 22 is curved upward, allowing the door-side end of the wire bundle 13 to be led upward from the support member-side outlet 24. In other words, the door-side end of the wire bundle 13 extends radially outward (forward) from the rotation axis Z of the door-side rotor 50, and is pulled upward from the support member-side outlet 24, which is an outlet position radially offset from the rotation axis Z.

[0025] The protector cover 31 has a top plate portion 32 formed in a shape that conforms to the shape of the protector body 21 when viewed from above, that is, the shape of the upper open portion. On the lower surface of the rear portion of the top plate portion 32, which extends horizontally along the front-to-back direction, there is a pivot hole 36 for mounting the door-side rotor 50 so as to be rotatable around a pivot axis Z.

[0026] Multiple engaging pieces 38 are provided on the periphery of the top plate portion 32. Multiple receiving portions 28 are provided on both side walls 23a and support side walls 23b of the protector body 21, corresponding to these engaging pieces 38. By engaging the engaging pieces 38 with the receiving portions 28, the protector cover 31 is locked in place, covering the upper open portion of the protector body 21.

[0027] As shown in Figures 3 and 4, the door-side rotor 50 comprises a door rotor body 41 placed on the bottom plate portion 22 of the protector body 21, and a door rotor cover 51 that covers the upper open portion of the door rotor body 41.

[0028] The door rotor body 41 has side wall portions 43a that face each other on either side of the wire bundle 13. The side wall portions 43a rise from both sides along the longitudinal direction of the bottom plate portion 42 which is arranged along the wire bundle 13. That is, the door rotor body 41 has a cross-sectional shape perpendicular to the longitudinal direction that is an open U shape at the top.

[0029] On the lower surface of the front portion of the bottom plate 42, which extends horizontally along the front-rear direction, a shaft portion 46 is formed to protrude and be rotatably fitted into the shaft support hole 26 of the protector body 21. Furthermore, on the outer circumference of the shaft portion 46, an engaging projection 47 is formed to engage with the engaging recess 27 of the protector body 21 to restrict the rotation range of the door-side rotor 50.

[0030] Furthermore, in the front portion of the door rotor body 41, a rotating side wall portion 43b is formed around the rotation axis Z to which the front ends of both side wall portions 43a are connected, in order to prevent interference from the bundle of electric wires 13 attached to the door side rotor 50 when it rotates.

[0031] Furthermore, the rear end portion of the door rotor body 41 is provided with a rotating member side outlet portion 44 that holds and fixes the end of the corrugated tube 11 surrounding the wire bundle 13. In other words, the vehicle body side end of the harness body 10 is led out from the rotating member side outlet portion 44 of the rotating door rotor body 41 so as to be able to swing freely in a predetermined angular direction.

[0032] The door rotor cover 51 has a top plate portion 52 that is shaped to resemble the shape of the door rotor body 41 when viewed from above, that is, the shape of the upper open portion. Along the longitudinal edge of the top plate portion 52, side wall portions 53 are provided that hang down from the outside of the side wall portions 43a of the door rotor body 41, respectively. On the upper surface of the front portion of the top plate 52, which extends horizontally along the front-to-back direction, a shaft portion 56 is formed to protrude and is rotatably fitted into the shaft support hole 36 of the protector cover 31.

[0033] Furthermore, multiple receiving portions 58 are provided on both side walls 53 of the door rotor cover 51. Multiple engaging pieces 48 are provided on both side walls 43a and the rotating side wall 43b of the door rotor body 41, corresponding to these receiving portions 58. When the engaging pieces 48 engage with the receiving portions 58, the door rotor cover 51 is locked in place, covering the upper open portion of the door rotor body 41.

[0034] Therefore, in the wire harness 1 according to this first embodiment, the wire bundle 13 at the door-side end of the harness body 10 attached to the door-side protector 20 is led upward from the support member-side outlet portion 24 of the protector body 21, and the vehicle body-side end of the harness body 10 is led out so as to be able to pivot in a predetermined angular direction from the rotation member-side outlet portion 44 of the door-side rotor 50.

[0035] Furthermore, when the door-side protector 20 is attached to the sliding door in a vertical position, the vehicle body end of the harness body 10 attached to the door-side protector 20 is connected to the door-side protector 20 so as to extend horizontally, and its direction within the horizontal plane can be arbitrarily changed.

[0036] Therefore, when the sliding door is opened or closed, the harness body 10 is bent in accordance with the opening and closing of the sliding door. As shown in Figures 1 and 2, this bending of the harness body 10 causes the door-side rotor 50 to rotate relative to the door-side protector 20.

[0037] Furthermore, in order to cover the wire bundle 13 exposed from the support-side opening 25 formed in the protector body 21 and the rotation-side opening 45 formed in the door rotor body 41, a shielding member 60 is provided between the door-side protector 20 and the door-side rotor 50, which expands and contracts in accordance with the rotation of the door-side rotor 50 relative to the door-side protector 20.

[0038] As shown in Figures 3 to 5, the shielding member 60 is a retractable blind comprising a first support pin 61 attached to the door-side protector 20, a second support pin 63 attached to the door-side rotor 50, a spiral spring 64 whose inner end is connected to the first support pin 61, and a flexible retractable blind 66 whose one end is connected to the outer end of the spiral spring 64 and whose other end is connected to the second support pin 63.

[0039] As shown in Figure 5, the first support pin 61 does not interfere with the door-side rotor 50 and is positioned near the opening end of the support-side opening 25 adjacent to the rear end of the left side wall portion 23a of the protector body 21. When the protector cover 31 is fixed to the protector body 21, the lower end of the first support pin 61 is fixed to a support hole 29 formed in the bottom plate portion 22 of the protector body 21, and the upper end is fixed to a support hole 39 (see Figure 4) formed in the top plate portion 32 of the protector cover 31.

[0040] As shown in Figure 5, the second support pin 63 is positioned near the opening end of the rotating side opening 45 adjacent to the front end of the left rotating side wall portion 43b of the door rotor body 41. As shown in Figure 4, when the door rotor cover 51 is fixed to the door rotor body 41, the lower end of the second support pin 63 is fixed to a support hole 49 (see Figure 3) formed in the bottom plate portion 42 of the door rotor body 41, and the upper end of the second support pin 63 is fixed to a support hole 59 formed in the top plate portion 52 of the door rotor cover 51.

[0041] As shown in Figure 5, the shielding member 60 is set such that when the sliding door is fully closed and the harness body 10 is extended in a substantially straight line, the distance between the first support pin 61 and the second support pin 63 is at its maximum, and when the sliding door is fully open and the harness body 10 is bent (see Figure 10), the distance between the first support pin 61 and the second support pin 63 is at its minimum.

[0042] Therefore, when the sliding door is fully open, the shielding member 60 is wrapped around the first support pin 61 by the winding force of the spiral spring 64, and when the sliding door is fully closed, it is pulled out against the winding force of the spiral spring 64.

[0043] Next, the operation of the wire harness 1 according to this first embodiment will be described. Figure 6 is a side view of the wire harness 1 shown in Figure 1, viewed from the left. Figure 7 is a top view of the wire harness 1 shown in Figure 6 with the door rotor cover 51 and protector cover 31 removed. Figure 8 is a side view of the wire harness 1 viewed from the left when the sliding door is half open. Figure 9 is a top view of the wire harness 1 shown in Figure 8 with the door rotor cover 51 and protector cover 31 removed. Figure 10 is a perspective view of the main part illustrating the operation of the shielding member 60 shown in Figure 3 when the sliding door is fully open.

[0044] As shown in Figures 6 and 7, according to the wire harness 1 of this first embodiment, when the sliding door is fully closed and the harness body 10 extends in a substantially straight line, the distance between the first support pin 61 and the second support pin 63 increases, and the shielding member 60 provided between the door-side protector 20 and the door-side rotor 50 extends, so that the bundle of wires 13 exposed from the support-side opening 25 and the rotation-side opening 45 can be covered.

[0045] Therefore, when the wire harness 1 is attached to the sliding door, the shielding member 60 hides the bundle of wires 13 that are exposed from the support-side opening 25 and the rotation-side opening 45 when the sliding door is fully closed, improving the appearance.

[0046] As shown in Figures 8 and 9, when the sliding door is half-open and the harness body 10 is bent at an obtuse angle, the distance between the first support pin 61 and the second support pin 63 narrows, and the shielding member 60 provided between the door-side protector 20 and the door-side rotor 50 contracts. As a result, the wire bundle 13 can be covered with an expansion and contraction length corresponding to the opening width of the support-side opening 25 and the rotation-side opening 45 without affecting the rotation of the door-side rotor 50.

[0047] Furthermore, in the wire harness 1 according to this first embodiment, the shielding member 60 is a retractable blind having a first support pin 61 attached to the door-side protector 20, a second support pin 63 attached to the door-side rotor 50, a spiral spring 64 whose inner end is connected to the first support pin 61, and a flexible retractable blind 66 whose one end is connected to the outer end of the spiral spring 64 and whose other end is connected to the second support pin 63.

[0048] Therefore, the shielding member 60 can smoothly extend and retract the winding blind 66 by the winding force of the spiral spring 64, in accordance with the distance between the first support pin 61 and the second support pin 63, which changes due to the rotation of the door-side rotor 50.

[0049] Furthermore, as shown in Figure 10, when the sliding door is fully open and the harness body 10 is bent at a sharp angle, the distance between the first support pin 61 and the second support pin 63 is minimized, and the shielding member 60 provided between the door-side protector 20 and the door-side rotor 50 becomes compact, wrapped around the first support pin 61. This prevents it from affecting the rotation of the door-side rotor 50 or interfering with the wire bundle 13.

[0050] Therefore, it is possible to provide a visually appealing wire harness 1 that is routed from the vehicle body to the sliding door.

[0051] (Reference example) Figure 11 is a perspective view of the main part of the wire harness 101 according to a reference example when the sliding door is fully open. Note that the wire harness 101 is configured in which the shielding member 60 of the wire harness 1 of the first embodiment described above is omitted, and the same reference numerals are used for similar components, and detailed explanations are omitted.

[0052] As shown in Figure 11, when the sliding door is fully closed and the harness body 10 extends in a nearly straight line, the bundle of wires 13 is visible from the support-side opening 25 and the rotation-side opening 45, resulting in a less aesthetically pleasing appearance.

[0053] (Second Embodiment) Figure 12 is an exploded perspective view of the wire harness 1A according to the second embodiment of the present invention. Figure 13 is a perspective view of the main part illustrating the operation of the shielding member 80 shown in Figure 12 when the sliding door is fully closed. Figure 14 is a perspective view of the main part illustrating the operation of the shielding member 80 shown in Figure 12 when the sliding door is fully open. Note that the wire harness 1A is configured using the shielding member 80 instead of the shielding member 60 in the wire harness 1 of the first embodiment, and similar components are denoted by the same reference numerals and detailed explanations are omitted.

[0054] As shown in Figures 12 to 14, the wire harness 1A according to the second embodiment of the present invention comprises a harness body 10, a door-side protector 20 through which the door-side end of the inserted harness body 10 is led out from a support member-side outlet 24 and fixed to the sliding door, a door-side rotor 50 that is rotatably mounted to the door-side protector 20 around a vertically extending pivot axis Z in order to lead out the vehicle body-side end of the harness body 10 from a pivot member-side outlet 44 in a direction of a predetermined angle, and a shielding member 80 for covering and concealing the wire bundle 13 exposed from a support-side opening 25 formed in the protector body 21 and a pivot-side opening 45 formed in the door rotor body 41.

[0055] As shown in Figures 12 to 14, the shielding member 80 is a folding blind comprising a first support pin 81 attached to the door-side protector 20, a second support pin 83 attached to the door-side rotor 50, and a long folding blind 86 with one end connected to the first support pin 81 and the other end connected to the second support pin 83.

[0056] The folding blind 86 is formed by arranging multiple nodes (thin hinge portions formed on the front and back surfaces of the flat plate members) 85 at equal intervals along the longitudinal direction of the flat plate members made of synthetic resin, and extending parallel to the width direction, so that multiple flat plate members 84 bend and overlap at the nodes 85 and fold up in an accordion-like manner.

[0057] As shown in Figure 13, the first support pin 81 does not interfere with the door-side rotor 50 and is positioned near the opening end of the support-side opening 25 adjacent to the rear end of the left side wall portion 23a of the protector body 21. When the protector cover 31 is fixed to the protector body 21, the lower end of the first support pin 81 is fixed to a support hole 29 formed in the bottom plate portion 22 of the protector body 21, and the upper end is fixed to a support hole 39 formed in the top plate portion 32 of the protector cover 31.

[0058] As shown in Figure 13, the second support pin 83 is positioned near the opening end of the rotating side opening 45 adjacent to the front end of the left rotating side wall portion 43b of the door rotor body 41. When the door rotor cover 51 is fixed to the door rotor body 41, the lower end of the second support pin 83 is fixed to a support hole 49 formed in the bottom plate portion 42 of the door rotor body 41, and the upper end of the second support pin 83 is fixed to a support hole 59 formed in the top plate portion 52 of the door rotor cover 51.

[0059] As shown in Figure 13, the shielding member 80 is set such that when the sliding door is fully closed and the harness body 10 is extended in a substantially straight line, the distance between the first support pin 81 and the second support pin 83 is at its maximum, and when the sliding door is fully open and the harness body 10 is bent (see Figure 14), the distance between the first support pin 81 and the second support pin 83 is at its minimum.

[0060] Therefore, when the sliding door is fully open, the shielding member 80 is in a state where multiple flat plate portions 84 of the folding blind 86 overlap, and when the sliding door is fully closed, the folding blind 86 is in a state where it is spread out into a long plate shape.

[0061] Therefore, according to the wire harness 1A of this second embodiment, when the sliding door is fully closed and the harness body 10 extends in a substantially straight line, the distance between the first support pin 81 and the second support pin 83 increases, and the shielding member 80 provided between the door-side protector 20 and the door-side rotor 50 extends, so that the bundle of wires 13 exposed from the support-side opening 25 and the rotation-side opening 45 can be covered.

[0062] Therefore, when the wire harness 1A is attached to the sliding door, the shielding member 80 hides the bundle of wires 13 that would otherwise be exposed from the support-side opening 25 and the rotation-side opening 45 when the sliding door is fully closed, improving the appearance.

[0063] Furthermore, in the wire harness 1A according to this second embodiment, the shielding member 80 is a folding blind having a first support pin 81 attached to the door-side protector 20, a second support pin 83 attached to the door-side rotor 50, and a long folding blind 86 with one end connected to the first support pin 81 and the other end connected to the second support pin 83.

[0064] Therefore, the shielding member 80 allows the folding blind 86, which folds in an accordion-like manner, to smoothly extend and retract according to the distance between the first support pin 81 and the second support pin 83, which changes as the door-side rotor 50 rotates.

[0065] Furthermore, as shown in Figure 14, when the sliding door is fully open and the harness body 10 is bent at a sharp angle, the distance between the first support pin 81 and the second support pin 83 is minimized, and the folding blind 86 of the shielding member 80 provided between the door-side protector 20 and the door-side rotor 50 is folded into a compact, bellows-like state, so as not to affect the rotation of the door-side rotor 50 or interfere with the wire bundle 13.

[0066] Therefore, it is possible to provide a visually appealing wire harness 1A that is routed from the vehicle body to the sliding door.

[0067] Furthermore, the present invention is not limited to the embodiments described above, and can be modified, improved, etc., as appropriate. In addition, the material, shape, dimensions, number, placement, etc. of each component in the embodiments described above are arbitrary and not limited, as long as they can achieve the present invention.

[0068] Herein, the features of the embodiments of the wire harness according to the present invention described above are briefly summarized and listed below in [1] to [3]. [1] The harness body (10) is routed from the vehicle body to the sliding door, The door-side end of the inserted harness body (10) is led out from the support member side outlet (24) and fixed to the sliding door by a support member (door-side protector 20), In order to allow the vehicle body side end of the harness body (10) to be led out from the rotating member side outlet (44) in a direction of a predetermined angle, a rotating member (door side rotor 50) is attached to the support member (door side protector 20) so as to be rotatable about a pivot axis (Z), In order to prevent the harness body (10) from interfering during rotation, a support-side opening (25) and a rotation-side opening (45) are provided in the support-side wall portion (23b) around the rotation axis (Z) of the support member (door-side protector 20) and the rotation-side wall portion (43b) around the rotation axis (Z) of the rotation member (door-side rotor 50), respectively. In order to cover the harness body (10) exposed from the support-side opening (25) and the rotation-side opening (45), shielding members (60, 80) are provided between the support member (door-side protector 20) and the rotation member (door-side rotor 50) and expand and contract in accordance with the rotation of the rotation member (door-side rotor 50), A wire harness (1,1A) equipped with [a specific feature].

[0069] With the wire harness (1,1A) configured as described in [1] above, when the sliding door is fully closed and the harness body (10) is extended in a nearly straight line, the shielding members (60,80) provided between the support member (door-side protector 20) and the rotating member (door-side rotor 50) are extended. As a result, the wire harness (1,1A) can cover the harness body (10) that is exposed from the support-side opening (25) of the support member (door-side protector 20) and the rotating-side opening (45) of the rotating member (door-side rotor 50), improving the appearance.

[0070] [2] The shielding member (60) is a retractable blind having a first support pin (61) attached to the support member (door-side protector 20), a second support pin (63) attached to the rotating member (door-side rotor 50), a spiral spring (64) whose inner end is connected to the first support pin (61), and a flexible retractable blind (66) whose one end is connected to the outer end of the spiral spring (64) and whose other end is connected to the second support pin (63). The wire harness (1) described in [1] above.

[0071] According to the wire harness (1) with the configuration described in [2] above, the shielding member (60) can be smoothly extended and retracted by the winding force of the spiral spring (64) in accordance with the distance between the first support pin (61) and the second support pin (63), which changes due to the rotation of the rotating member (door-side rotor 50). Furthermore, when the sliding door is fully open and the harness body (10) is bent at a sharp angle, the distance between the first support pin (61) and the second support pin (63) is minimized, and the shielding member (60) provided between the support member (door-side protector 20) and the rotating member (door-side rotor 50) becomes compact, wrapping around the first support pin (61). As a result, it does not affect the rotation of the rotating member (door-side rotor 50) or interfere with the harness body (10).

[0072] [3] The shielding member (80) is a folding blind having a first support pin (81) attached to the support member (door-side protector 20), a second support pin (83) attached to the rotating member (door-side rotor 50), and a long folding blind (86) with one end connected to the first support pin (81) and the other end connected to the second support pin (83). The wire harness (1A) described in [1] above.

[0073] According to the wire harness (1A) with the configuration described in [3] above, the shielding member (80) allows the folding blind (86), which folds in an accordion-like manner, to smoothly extend and retract in accordance with the distance between the first support pin (81) and the second support pin (83), which changes due to the rotation of the support member (door-side rotor 50). Furthermore, when the sliding door is fully open and the harness body (10) is bent at a sharp angle, the distance between the first support pin (81) and the second support pin (83) is minimized, and the folding blind (86) of the shielding member (80) provided between the support member (door-side protector 20) and the rotating member (door-side rotor 50) is folded into a compact, bellows-like state, so as not to affect the rotation of the rotating member (door-side rotor 50) or interfere with the harness body (10).
