For convenience of explanation, first, the relationship between the vehicle body 12 of the automobile 10 and the slide door 14 to which the present wire harness support and the conductive path device are applied will be described (see FIGS. 1 to 3).

  The automobile 10 includes a vehicle body 12 and a slide door 14 provided on one side of the vehicle body 12. A boarding opening 13 through which a person can get on and off the vehicle body 12 is provided at one side of the vehicle body 12. The slide door 14 has a closed position P1 (see FIG. 2) for closing the boarding port 13 and an open position P2 (see FIG. 3) for opening the boarding port 13 by a slide support mechanism including a guide rail (not shown). Is supported so as to be movable between.

  More specifically, the slide door 14 is movable between the closed position P1 and the open position P2 on the rear side of the vehicle body 12 from the closed position P1 by moving mainly in the front-rear direction of the vehicle body 12. . As the slide door 14 moves from the closed position P1 to the open position P2, the slide door 14 also moves outward in the vehicle width direction in order to avoid interference with the vehicle body 12. At this time, the sliding door 14 is set so that the movement amount of the lower end portion is larger than the movement amount of the upper end portion in the vehicle width direction. For this reason, the lower end portion of the slide door 14 is positioned relatively higher with respect to the upper end portion in the state where the slide door 14 is in the open position P2 than in the state where the slide door 14 is in the closed position P1 ( (See FIG. 3). Further, the slide door 14 as a whole may be set so that the open position P2 is positioned higher than the closed position P1 in the vertical direction of the vehicle body 12.

  Accordingly, the slide door 14 is also moved upward with respect to the vehicle body 12 when being moved from the closed position P1 to the open position P2.

<2. Configuration of Conductive Path Device>
A configuration of the conductive path device 20 according to the present embodiment will be described (see FIGS. 4 and 6). 4 and 6 to 12 show a case where the conductive path device 20 (wire harness support) is applied to the slide door 14 disposed on the left side of the vehicle body 12.

  The conductive path device 20 is a device for constantly supplying power from the vehicle body 12 side to various electrical components such as a power window, a door lock, and various operation switches provided in the slide door 14 of the automobile 10. The conductive path device 20 is disposed between the vehicle body 12 and the slide door 14 as shown in FIGS.

  The conductive path device 20 includes a wire harness (hereinafter referred to as a conductive harness 30), a guide member 40, and a wire harness support (slide door side support 50) (see FIG. 6).

  The conductive harness 30 is configured to be bent by bundling a plurality of electric wires in a linear shape. The conductive harness 30 is configured to electrically connect the various electrical components provided in the slide door 14 and various electrical components (various operation switches, electronic control units, batteries, etc.) on the vehicle body 12 side. 12 and the sliding door 14 are arranged.

  The guide member 40 is configured to be able to guide the conductive harness 30 mainly on one plane. The guide member 40 is configured to be externally mounted on the conductive harness 30 and thereby guide the conductive harness 30 so as to bend (change in angle) on one plane.

  More specifically, the guide member 40 has a plurality of link members 42 having a pair of opposing side pieces supported at intervals, and each of the link members 42 rotates around a predetermined connecting shaft. It is the structure connected so that it was possible (refer FIG. 6). As a result, the guide member 40 as a whole is configured as a linear member that can be bent (change in angle) on a plane substantially orthogonal to the predetermined connecting shaft (the vertical direction in FIGS. 4 and 6). The guide member 40 is formed with a guide path portion 46 through which the conductive harness 30 can be inserted along the longitudinal direction between a pair of opposing side pieces of each link member 42. The guide member 40 guides the conductive harness 30 mainly on a single plane in a state where the conductive harness 30 is inserted into the guide path portion 46. Such a guide member 40 is also called a cable bearer (registered trademark).

  The guide member 40 is preferably covered with a protective material 48 such as a rectangular tube corrugated tube in order to prevent contact with other members in the slide door 14 or between the vehicle body 12 and the slide door 14. (See FIG. 4).

  The guide member 40 can be bent (change in angle) mainly on one plane by supporting both ends in the longitudinal direction with respect to support members disposed on the vehicle body 12 side and the slide door 14 side, respectively. It is bridged between the vehicle body 12 and the slide door 14 in a posture. That is, as the slide door 14 moves between the closed position P1 and the open position P2, the guide member 40 that guides the conductive harness 30 mainly operates on a single plane. Here, the one plane on which the guide member 40 disposed between the vehicle body 12 and the slide door 14 operates is approximately the position of the support on the vehicle body 12 side and the movement path of the support on the slide door 14 side. It is a plane including. The conductive harness 30 and the guide member 40 provided between the vehicle body 12 and the slide door 14 are also referred to as a transition portion.

  In the conductive path device 20, the guide member 40 is configured such that at least one end on the vehicle body 12 side or the slide door 14 side is supported by the wire harness support. Here, one end of the guide member 40 is supported by the slide door side support 50 as a wire harness support with respect to the slide door 14, and the other end is supported by the vehicle body side support 80 with respect to the vehicle body 12. Will be described (see FIGS. 9 and 10).

  The vehicle body side support member 80 supports the end portion of the guide member 40 on the vehicle body 12 side by connecting one link member 42 on the vehicle body 12 side of the guide member 40 so as to be rotatable around a predetermined connection shaft. It is a structure (refer FIG. 9, FIG. 10). However, the guide member 40 may be supported by fixing one link member 42 on the vehicle body 12 side to the vehicle body side support 80. The vehicle body side support 80 is attached to the vehicle body 12 directly or indirectly by screwing or the like. The vehicle body side support 80 is configured to be able to guide the conductive harness 30 inserted into the guide member 40 toward the vehicle body 12. As such a configuration, it is possible to employ a configuration having a guide path that opens on the side connected to the guide member 40 and the vehicle body 12 side. The conductive harness 30 guided to the vehicle body 12 side is electrically connected to various electrical components on the vehicle body 12 side or cables connected thereto.

  The slide door side support tool 50 includes a guide support portion 60, a support main body portion 70, and an urging member 54 (see FIGS. 4 and 6).

  The guide support portion 60 is configured to be attached to the end portion of the guide member 40 on the slide door 14 side. The guide support portion 60 includes a supported portion 62 and a connecting portion 64, and the supported portion 62 and the connecting portion 64 are continuously formed along one direction (see FIG. 6). .

  The supported portion 62 is formed with a pair of supported convex portions 63 that protrude upward and downward (both sides in a direction substantially parallel to a predetermined connection axis of the connecting portion 64 and the guide member 40 described later). Yes. The supported portion 62 is provided with a pair of supported convex portions 63 in a pair of support concave portions 73 that open upward and downward in a concave portion 72 of a support main body portion 70 to be described later. Thus, the posture can be changed with respect to the support main body 70. More specifically, the pair of supported convex portions 63 are formed on one phantom spherical surface (see FIG. 6). The pair of supported convex portions 63 are formed at opposing positions on the phantom spherical surface in the vertical direction of the vehicle body 12. Here, each of the pair of supported convex portions 63 has a supported surface 63a that can come into contact with a pair of support surfaces 73a of a support concave portion 73 of the support main body portion 70 described later. Each of the supported surfaces 63a is a substantially spherical partial spherical surface in plan view that faces the outside. But the to-be-supported part 62 may be formed in the substantially spherical frame as a whole.

  Further, the supported portion 62 has a substantially cylindrical regulated projection that protrudes downward from the center position of the supported surface 63a of the lower supported convex portion 63 (a position on the inner side of the substantially annular shape in plan view). A portion 68 is formed.

  Furthermore, a guide path, which will be described later, is provided in the supported portion 62 so as to open upward at the center position of the supported surface 63a of the upper supported convex portion 63 (a position on the inner side of the substantially annular shape in plan view). A second opening 66b of the portion 66 is formed.

  The connecting portion 64 is configured to be connectable to an end portion of the guide member 40 on the slide door 14 side. More specifically, the connecting portion 64 is configured such that one link member 42 on the slide door 14 side of the guide member 40 is connected so as to be rotatable around a predetermined connecting axis. However, the guide member 40 may be connected to the connecting portion 64 by fixing one link member 42 on the slide door 14 side.

  Further, the guide support portion 60 is configured to guide the conductive harness 30 from the first opening 66 a formed in the connecting portion 64 to the second opening 66 b on the slide door 14 side. More specifically, the guide support portion 60 is formed with a guide path portion 66 that is opened by a first opening 66a and a second opening 66b (see FIG. 6). The first opening 66a is formed in the connecting portion 64 so as to open from the supported portion 62 side toward the connecting portion 64 side. The first opening 66a and the second opening 66b are formed so as to open in a substantially orthogonal direction (in FIG. 6, the first opening 66a is on the left side and the second opening 66b is on the upper side).

  The support main body portion 70 is disposed on the slide door 14 corresponding to the guide support portion 60 so that the connecting portion 64 can swing around the predetermined rotation axis A and can swing in the predetermined rotation axis A direction. Further, the guide support unit 60 is configured to support the posture changeable (see FIGS. 4 and 6).

  The support main body 70 can be attached to the slide door 14 directly or indirectly (for example, to a member movable along a guide rail (not shown) provided in the slide door 14) by screwing or the like. It is configured. Hereinafter, the support body 70 will be described based on the posture attached to the left sliding door 14 of the vehicle body 12.

  The support main body 70 has a recess 72 in which the guide support 60 can be disposed so that its posture can be changed. The recess 72 is formed so as to open continuously in two directions of the support main body 70 (left side and front side in FIG. 4). The support main body 70 is disposed in the slide door 14 in such a posture that the recess 72 opens toward the rear of the vehicle body 12 and the inner side (right) in the width direction (see FIG. 4).

  The support main body 70 is formed with a pair of support recesses 73 that open upward and downward, respectively. More specifically, the pair of support recesses 73 are formed on one phantom spherical surface. The phantom sphere is slightly larger than the phantom sphere on which the supported convex portion 63 is formed. The pair of support recesses 73 are formed at opposing positions on the phantom spherical surface in the vertical direction of the vehicle body 12. Here, each of the pair of support recesses 73 has a support surface 73 a that can contact the supported surface 63 a of the guide support portion 60 disposed in the recess 72. Each of the pair of support surfaces 73a is an approximately circular partial spherical surface in plan view that faces inward (see FIG. 7).

  Further, the support main body 70 has a regulation recess 78 that can regulate the posture change of the guide support 60 when the connecting part 64 swings in the predetermined rotation axis A direction (see FIG. 6). The regulating recess 78 opens in a substantially circular shape toward the inside of the recess 72 at the center position of the other supporting surface 73a of the pair of supporting surfaces 73a (inner position in a substantially annular shape in plan view), and the inner peripheral surface is regulated. The protrusion 68 is formed in a concave shape having a substantially circular shape when viewed from the cross section. More specifically, the restricting recess 78 is formed to gradually increase in diameter in a direction away from the recess 72 (toward the lower side). Then, the posture change of the guide support portion 60 is restricted in a state where the inner peripheral surface of the restricting recess 78 is in contact with the outer peripheral surface of the restricted protrusion 68. The restriction range of the swinging operation of the guide support part 60 by the restriction recess 78 may be determined based on the inclination of the guide member 40 at the closed position P1 and the open position P2 of the slide door 14.

  The guide support portion 60 is disposed in the recess 72 of the support main body portion 70 and can change its posture in a three-dimensional direction in a state where the pair of supported surfaces 63a are in contact with the pair of support surfaces 73a. That is, the guide support part 60 can swing around the predetermined rotation axis A passing through the center of the phantom sphere along the vertical direction of the vehicle body 12 and swing in the predetermined rotation axis A direction. The support main body 70 is supported. Here, that the connecting portion 64 can swing in the direction of the predetermined rotation axis A means that the connection portion 64 can swing around an axis that is substantially orthogonal to the predetermined rotation axis A and passes through the center of the phantom sphere. The guide support portion 60 is swung approximately in the direction of the predetermined rotation axis A because the swinging operation is restricted within a certain range by the regulated protrusion 68 coming into contact with the restriction recess 78.

  But the structure for the guidance support part 60 to change an attitude | position is not restricted to the said structure. For example, the guide support portion 60 is supported by the support main body portion 70 so as to be rotatable by one shaft portion along a predetermined rotation axis A, and the other shaft portion is substantially orthogonal to the shaft portion. The connecting portion 64 may be configured to be swingable around one shaft portion and swingable around the other shaft portion by being supported by the rotation.

  The support main body 70 further guides the conductive harness 30 guided from the second opening 66 b to the slide door 14 through the guide path 66 of the guide support 60 to the slide door 14. (See FIG. 6). More specifically, the main body side guide portion 76 is formed in a substantially cylindrical shape through which the conductive harness 30 can be inserted, and opens toward the inside of the recess 72 and the outside of the support main body portion 70 (inside the slide door 14). Yes. Here, the main body side guide portion 76 opens into the recess 72 at the center portion (a substantially annular inner portion in plan view) of one support surface 73a of the pair of support surfaces 73a, along the vertical direction of the vehicle body 12. Is formed. The opening on the concave portion 72 side of the main body side guide portion 76 is set to have a larger diameter than the second opening portion 66 b of the guide support portion 60.

  The conductive harness 30 guided into the slide door 14 by the main body side guide portion 76 is electrically connected to various electrical components equipped on the slide door 14 or cables connected thereto.

  The urging member 54 is configured to be able to urge the guide support portion 60 to swing the connecting portion 64 toward the support main body portion 70 in a direction opposite to gravity (upward in the vertical direction of the vehicle body 12). ing. At least one of the positions of the connecting portion 64 around the predetermined rotation axis A in a state where the slide door 14 is in the middle position between the closed position P1 and the open position P2, the urging member 54 is provided with the guide support portion 60. It is good to be configured so that it can be used. Preferably, the biasing member 54 may bias the guide support portion 60 at a position where the most drooping of the guide member 40 that guides the conductive harness 30 is expected to occur.

  That is, the biasing member 54 may be disposed so as to bias the guide support portion 60 in the entire operation range of the connecting portion 64 around the predetermined rotation axis A as long as it includes the above position. And it may be arrange | positioned so that urging | biasing is possible in the partial range among the whole operation | movement ranges of the connection part 64.

  Considering in plan the sagging due to the weight of the guide member 40, it is considered that the sagging occurs most at the position where the vehicle body side support tool 80 and the wire-harness support tool 50 face each other in the width direction of the car body 12. Actually, since the present conductive path device 20 is intended for the sliding door 14 that also moves in the vertical direction of the vehicle body 12 when opening and closing, the vertical direction of the vehicle body 12 between the vehicle body side support tool 80 and the slide door side support tool 50. It is considered that the position where the guide member 40 hangs most changes depending on the positional relationship in the width direction. That is, the position at which the guide member 40 is most hung down is determined by the moving path of the slide door 14 with respect to the vehicle body 12 of the target automobile 10, the arrangement positional relationship between the vehicle body side support tool 80 and the slide door side support tool 50, and the like.

  Here, the urging member 54 is a metal leaf spring having one bent portion 54a (see FIG. 5). The urging member 54 is disposed in a compressed state between the lower end portion of the portion of the guide support portion 60 closer to the connecting portion 64 than the predetermined rotation axis A and the support main body portion 70 (FIG. 4, FIG. 6). More specifically, the urging member 54 is in a posture in which the bent portion 54a is directed from the connecting portion 64 to the supported portion 62, and the lower end portion of the guide support portion 60 on the connecting portion 64 side from the predetermined rotation axis A. (See FIG. 7). As an arrangement mode of the urging member 54, it may be adhered to the guide support portion 60, or a fitting portion or an insertion portion is formed in the guide support portion 60 in advance, and these portions are attached to the guide support portion 60. It may be fixed by fitting or inserting. Further, the urging member 54 may be integrally formed with the guide support portion 60 by insert molding or the like.

  However, the biasing member 54 is not limited to a leaf spring, and a coil spring or other elastic member can be employed. Further, the urging member 54 is not limited to the case of being attached to the guide support part 60, and may be attached to the support main body part 70. When attached to the support main body 70, the biasing member 54 is arranged around the predetermined rotation axis A in the entire operation range of the connecting portion 64 or a part thereof. Further, the biasing member 54 is limited to a mode in which the biasing member 54 is disposed in a compressed state between the lower end portion of the portion of the guide support portion 60 closer to the connecting portion 64 than the predetermined rotation axis A and the support main body portion 70. It is not a thing. For example, the urging member 54 is connected between the upper end portion of the guide support portion 60 on the connection portion 64 side with respect to the predetermined rotation axis A and the support main body portion 70 or with the connection portion 64 with respect to the predetermined rotation axis A. May be disposed between the guide support portion 60 and the support main body portion 70 at the opposite position. In this case, the urging member 54 may be arranged in an expanded / contracted state according to the arrangement position. That is, the urging member 54 only needs to be able to urge the guide support portion 60 relative to the support main body portion 70 so that the connecting portion 64 swings upward.

  In the case where the guide support portion 60 is urged in a part of the entire operation range of the connecting portion 64 around the predetermined rotation axis A, the following configuration can be adopted. For example, as the urging member, an elastic member (a leaf spring or the like) having a convex portion projecting upward in a part of the circumferential direction in an arc shape in plan view can be employed. More specifically, the urging member may be formed in a shape that rises so that the upper surface becomes a smooth slope. The biasing member is fixed to the support main body 70 along the circumferential direction of the predetermined rotation axis A at a position between the guide support 60 and the support main body 70, so that the guide support The structure which energizes 60 in the said partial range is obtained. The convex portion of the urging member may be formed, for example, at an intermediate position in an arc shape in plan view or a position from one end portion to the middle portion according to a range in which the urging force is desired to be applied.

  So far, the example in which the slide door side support 50 supports the slide door 14 side end of the guide member 40 has been described, but the conductive path device 20 is not limited to this configuration. For example, the conductive path device 20 has a configuration in which a support (wire harness support) having the same configuration as the slide door-side support 50 is disposed so as to support the vehicle body 12 side end of the guide member 40, or The structure arrange | positioned so that both ends may be supported may be sufficient.

<3. Operation of conductive path device>
Next, the operation of the conductive path device 20 will be described with reference to FIGS. As described above, FIGS. 9 to 12 show a case where the conductive path device 20 is disposed on the slide door 14 disposed on the left side of the vehicle body 12.

  Here, an example in which the conductive path device 20 is disposed on the slide door 14 disposed on the left side of the vehicle body 12 in the automobile 10 will be described. Further, the positional relationship between the vehicle body side support tool 80 and the connection part 64 of the guide support part 60 in the vertical direction of the vehicle body 12 is such that the connection part 64 is lower than the vehicle body side support tool 80 when the slide door 14 is in the closed position P1. It is assumed that the connecting portion 64 is at a position higher than the vehicle body side support 80 in a state where the sliding door 14 is in the open position P2 (see FIG. 9).

  First, an operation when the slide door 14 is moved from the closed position P1 to the open position P2 will be described. In the state where the slide door 14 is in the closed position P1, the guide member 40 is maintained in a state of being stretched between the vehicle body side support tool 80 and the slide door side support tool 50 (see FIG. 9). At this time, in the guide support portion 60, the connecting portion 64 is directed obliquely upward by the guide member 40 toward the vehicle body side support member 80, and the urging force in the direction (upward) opposite to the tensile force and the gravity of the urging member 54. It is in a posture (see FIG. 11).

  When the slide door 14 starts to move from the closed position P1 toward the open position P2, the slide door side support tool 50 moves relatively upward in the vertical direction of the vehicle body 12 with respect to the vehicle body side support tool 80. Go.

  Here, considering the case where the urging member 54 is not provided in the slide door side support tool 50, the connecting portion 64 of the guide support part 60 gradually moves in the direction of gravity (downward) due to the positional relationship with the vehicle body side support tool 80. Swing towards the head. Further, the connecting portion 64 is directed obliquely downward due to the weight of the guide member 40 slackened between the slide door side support tool 50 and the vehicle body side support tool 80 in plan view. Thereby, the intermediate part of the guide member 40 and the conductive harness 30 (crossover part) will be in the state which hung down.

  In the conductive path device 20, even when the guide member 40 is loosened between the slide door side support 50 and the vehicle body support 80 in plan view (see P3 in FIG. 10), the slide door 14 moves from the closed position P1. The connecting portion 64 is maintained obliquely upward by the urging force of the urging member 54 until the position P3 in the middle of moving toward the open position P2 (see FIG. 11). At this time, the connecting portion 64 side portion of the guide member 40 is inclined obliquely upward along the posture of the connecting portion 64 toward the other end side. As a result, the conductive harness 30 guided by the guide member 40 is also positioned obliquely upward toward the other end side between the connecting portion 64 of the guide support portion 60 and the guide member 40.

  When the sliding door 14 is further moved from the midway position P3, the guide support portion 60 swings the connecting portion 64 downward from the initial posture due to the positional relationship of the vehicle body side support 80 with the vehicle body 12 in the vertical direction. Thus, the posture is changed (see FIG. 4). Even in this state, the guide member 40 is supported without drooping between the sliding door side support member 50 and the vehicle body side support member 80 by the urging force of the urging member 54 opposite to the direction of gravity (see FIG. 9). ).

  When the slide door 14 is moved to the open position P2, the guide support portion 60 is disposed at a position higher than the vehicle body side support tool 80 (see FIG. 9). At this time, the guide member 40 is extended obliquely downward from the guide support part 60 side toward the vehicle body side support tool 80 side due to the positional relationship between the vehicle body side support tool 80 and the guide support part 60. And the guide support part 60 becomes the attitude | position which the connection part 64 faced diagonally downward with the tensile force by the guide member 40 (refer FIG. 12). In this state, the urging member 54 is pressed between the guide support portion 60 and the support main body portion 70, and has a shape compressed from the initial state. Even in this state, the urging member 54 urges the guide support portion 60 so that the connecting portion 64 swings upward.

  Next, an operation when the slide door 14 is moved from the open position P2 to the closed position P1 will be described.

  When the slide door 14 starts to move from the open position P2 toward the closed position P1, the slide door side support tool 50 moves relatively downward in the vertical direction of the car body 12 with respect to the car body side support tool 80. (See FIG. 9).

  As the slide door 14 moves, the guide support portion 60 changes its posture so that the connecting portion 64 swings upward (in the order of FIGS. 12, 4, and 11) by the urging force of the urging member 54. It will be done. As a result, the guide member 40 is supported without drooping between the slide door side support tool 50 and the vehicle body side support tool 80 by the biasing force of the biasing member 54 opposite to the direction of gravity.

  When the regulated protrusion 68 of the guide support portion 60 contacts the restriction recess 78 of the support main body portion 70, the swinging motion of the connecting portion 64 in the predetermined rotation axis A direction is restricted, and the guide support portion 60 is in this posture. It is swung around the predetermined rotation axis A as it is (see FIG. 11).

  When the slide door 14 is moved to the closed position P <b> 1, the guide support portion 60 is caused by the urging force in the direction (upward) opposite to the gravity of the urging member 54 and the gravity of the urging member 54 toward the vehicle body side support 80. The connecting portion 64 is inclined obliquely upward (see FIG. 11).

  According to the slide door side support 50 and the conductive path device 20 configured as described above, at least the connection around the predetermined rotation axis A in the state where the slide door 14 is in the middle position between the closed position P1 and the open position P2. The guide support part 60 is urged by the urging member 54 so as to swing the connection part 64 in the direction opposite to the gravity at one position among the positions of the part 64. For this reason, it is possible to support the conductive harness 30 and the guide member 40 so as to be operable in a three-dimensional direction while suppressing the sagging due to their own weight. Thereby, the clearance set between the electrically conductive harness 30 (guide member 40 and the protective material 48) and peripheral components can be made small, and it can respond also to vehicles with various severe restrictions, such as a layout.

  Further, since the urging member 54 is expanded and contracted, the connecting portion 64 of the guide support portion 60 has a predetermined rotation axis while the urging member 54 is expanded and contracted according to the vertical positional relationship of each end of the guide member 40. The guide member 40 and the conductive harness 30 can be supported in a desired posture at each position of the slide door 14 by swinging in the A direction. Further, since the biasing member 54 expands and contracts according to the moving path of the slide door 14 and the positional relationship between the slide door side support tool 50 and the vehicle body side support tool 80, the conductive harness 30 and the guide member 40 are suspended. Parts for suppression can be shared, and the creation of new parts for each vehicle can be omitted.

  Further, when the biasing member 54 is configured to bias the guide support portion 60 over the entire operating range of the connecting portion 64 around the predetermined rotation axis A, the conductive harness 30 and the guide member 40 are more stably. Can be prevented from drooping.

  Further, when the urging member 54 is configured to partially urge the guide support portion 60, the guide support portion 60 and the support main body portion 70 are not affected by the urging force by the urging member 54. It is possible to suppress an excessive force from being applied. Thereby, durability of an apparatus can be improved.

  Further, since the biasing member 54 directly pushes up the portion of the guide support portion 60 on the side of the connecting portion 64 to which the guide member 40 is connected, the sagging due to the weight of the conductive harness 30 and the guide member 40 can be more reliably prevented. Can be suppressed.

  Further, since the urging member 54 is a leaf spring, it can be brought into surface contact with at least one of the guide support portion 60 or the support main body portion 70 and can be urged in a direction substantially orthogonal to the surface. The urging direction of 54 itself and the urging force of the connecting portion 64 acting on the guide support portion 60 in the swinging direction can be arranged in substantially the same direction. And when the space which can be arrange | positioned is small, for example, in this embodiment, even when arrange | positioning in the clearance gap between the support main-body part 70 of the guide support part 60, an urging | biasing force can be made to act more efficiently. Thereby, the sagging due to the weight of the conductive harness 30 and the guide member 40 can be more reliably suppressed.
