JP 2001-246993 A

  By the way, in the wire harness routed between the vehicle body and the luggage door, an extra length portion is provided between the luggage arm and the body in the vehicle width direction in order to suppress the load caused by the expansion and contraction of the wire harness when the luggage door is opened and closed. However, each time the luggage door is opened and closed, a twisting force is applied to the extra length, which causes a problem in terms of durability. In addition, it is necessary to secure a space for extending the extra length between the luggage arm and the body, and space saving is required.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a wiring structure of a wire harness that is excellent in durability and can save space.

  In order to achieve the above-described object, the wiring structure of the wire harness according to the present invention is characterized by the following (1) to (5).

(1) A wiring structure of a wire harness that is routed between a vehicle body and a door that is supported to be opened and closed with respect to the body by an opening and closing mechanism,
The opening / closing mechanism has an arm having one end rotatably connected to the body and the other end fixed to the door,
The wire harness is
A movable region that is routed along the arm and is deformable following the rotation of the arm by opening and closing the door, between the body and the arm,
The movable region is
A wiring structure of a wire harness, comprising two bent portions that are arranged along a direction orthogonal to the rotation axis of the arm and bent in opposite directions.
(2) The wiring structure of the wire harness according to (1), wherein the movable region includes a movable exterior member through which a plurality of piece members are rotatably connected to each other and a wire bundle is inserted therethrough.
(3) The wire harness according to (1), wherein the movable region is formed in a flat shape in cross section, and is arranged along a direction in which a width direction is orthogonal to a bending direction in the bent portion. The routing structure.
(4) The wiring structure of the wire harness according to (3), wherein the movable region is disposed at the same position as the arm in the rotation axis direction of the arm.
(5) An arm cover that covers the arm along which the wire harness is placed together with the wire harness,
The arm cover includes a protection portion having a pair of side plates that protrude to the movable region side and cover a part of both sides of the movable region with the door closed. The wiring structure of the wire harness as described in any one of 4).

According to the wiring structure of the wire harness configured as described in (1) above, the movable region of the wire harness that extends from the body to the arm and is routed along the arm is in a direction perpendicular to the rotation axis of the arm. Therefore, when the arm is rotated by opening and closing the door, the movable region follows the rotation of the arm without being twisted. Therefore, it is possible to suppress the twisting force from being applied to the wire harness, and to improve the durability.
In addition, the movable region of the wire harness that expands and contracts following the rotation of the arm has two bent portions that are bent in opposite directions to each other, so that the protrusion to the periphery is suppressed even when the arm is contracted. Thereby, the space which accommodates the movable area | region of a wire harness can be made as small as possible, and space saving can be achieved.
According to the wire harness having the configuration (2), when the door is opened and closed and the arm is rotated, the piece members of the movable exterior member are rotated with each other. Thereby, a movable area | region can be made to follow smoothly with respect to an arm.
According to the wire harness having the above configuration (3), when the door is opened and closed and the arm is rotated, the movable region having a flat cross-sectional shape is smoothly deformed in the thickness direction. Thereby, a movable area | region can be made to follow smoothly with respect to an arm.
According to the wire harness having the configuration of (4) above, the movable region is arranged at the same position as the arm in the direction of the rotation axis of the arm, so that the arm and the movable region of the wire harness are connected to the rotation axis of the arm. Since they are stacked in the orthogonal direction, further space saving can be achieved.
According to the wiring structure of the wire harness having the configuration of the above (5), the movable region of the wire harness is guided while being protected by the pair of side plates of the protection portion of the arm cover when the door is opened and closed. Therefore, the movable region is always deformed in a stable posture while suppressing interference with surrounding members and the like.
Moreover, the protection part is formed so that a part in the both sides of a movable area | region may be covered in the state which closed the door. Therefore, the size can be made as small as possible compared with a structure that covers the entire periphery of the movable region with the door closed. As a result, the turning radius of the protective portion when the door is opened and closed can be reduced, for example, interference with a trim provided along the inner wall of the luggage space can be prevented, and the arm can be accommodated on the back side of the trim. The space can be reduced and the luggage space can be expanded.

  ADVANTAGE OF THE INVENTION According to this invention, the wiring harness wiring structure which is excellent in durability and can aim at space saving can be provided.

(First embodiment)
First, the wiring structure of the wire harness according to the first embodiment will be described.
1A and 1B are diagrams for explaining the wiring structure of the wire harness according to the first embodiment. FIG. 1A is a side view of an opening / closing mechanism when the luggage door is in a fully closed state, and FIG. It is a perspective view of an opening and closing mechanism when the luggage door is in a fully closed state. FIG. 2 is a top view of the opening / closing mechanism for explaining the wire harness routing structure according to the first embodiment. FIG. 3 is a front view of the opening / closing mechanism for explaining the wiring structure of the wire harness according to the first embodiment.

  As shown in FIGS. 1 to 3, the wire harness 10 </ b> A routed in the routing structure according to the first embodiment is provided between the vehicle body 11 and the luggage door 12. The body 11 and the luggage door (door) 12 are connected by an opening / closing mechanism 13. The wire harness 10 </ b> A is assembled to the opening / closing mechanism 13.

  The opening / closing mechanism 13 includes a bracket 15 and a luggage arm (arm) 16. The bracket 15 is fixed to the body 11. The luggage arm 16 has a curved portion 17 curved in a U shape. The luggage arm 16 has a connecting portion 18 that is rotatably supported with respect to the bracket 15 on one end side, and is disposed on the lower side of the bracket 15 so that the bending portion 17 bulges downward. The luggage arm 16 has a fixing portion 19 on the other end side, and the fixing portion 19 is fixed to the lower surface side of the luggage door 12. One end of a U-shaped link 21 is connected to the luggage arm 16 near the connecting portion 18 in the curved portion 17. The other end of the link 21 is connected to one end of a U-shaped spring member 22, and the other end of the spring member 22 is connected to the bracket 15.

  In the opening / closing mechanism 13, when the luggage door 12 is opened / closed, the luggage arm 16 rotates around a connection point with the bracket 15. At this time, the opening / closing operation of the luggage door 12 is assisted by the biasing force of the spring member 22, so that the luggage door 12 can be easily opened / closed.

  An arm cover 25 is attached to the luggage arm 16 of the opening / closing mechanism 13. The arm cover 25 is provided from the fixed portion 19 to the middle of the bending portion 17 in the luggage arm 16.

  The arm cover 25 has a bottom plate portion 26 disposed along the lower portion of the luggage arm 16 and side plate portions 27 extending upward from both side edges of the bottom plate portion 26. The arm cover 25 has a larger width dimension than the luggage arm 16, and is attached to the luggage arm 16 while being moved toward one side in the width direction. As a result, the arm cover 25 is formed with a harness housing space 28 formed in a groove shape on one side of the luggage arm 16.

  A wire harness 10A is assembled to the opening / closing mechanism 13 to which the arm cover 25 is attached. 10 A of wire harnesses have the electric wire bundle 32 which bundled the several electric wire 31, and the connector 33 connected to the connector (illustration omitted) of the electric power feeding side provided in the body 11 side is provided in the one end side. Yes. The other end of the wire harness 10 </ b> A is connected to an electrical component such as a tail lamp provided on the luggage door 12, so that power can be supplied to the electrical component.

  The wire harness 10A has a movable region 35 on the connector 33 side and a fixed region 36 on the electrical component side. The movable region 35 is configured by passing the wire bundle 32 through the movable exterior member 40. The movable region 35 has a body fixing portion 41 at an end portion on the connector 33 side, and an arm fixing portion 42 at an end portion on the fixing region 36 side. The body fixing portion 41 is attached to the body 11 from below in the direction of arrow A in FIGS. 1A and 7B, and is fixed by a fixing member such as a screw fixing, a clamp, or an adhesive material. It is fixed by adhesive tape. The arm fixing portion 42 is attached to the bending portion 17 of the luggage arm 16 from the side in the direction of arrow B in FIGS. 2 and 7B, and is fixed by a fixing member such as a screw fixing and a clamp. It is fixed or bonded and fixed with an adhesive or adhesive tape. The fixed region 36 is configured by passing the wire bundle 32 through an exterior member such as a corrugated tube, and is accommodated in the harness accommodating space 28 of the arm cover 25.

  As shown in FIG. 3, the power supply wire harness 20 connected to the connector 33 of the wire harness 10 </ b> A is fixed along the inner surface of the body 11.

  FIG. 4 is a side view of the movable exterior member provided in the movable region. FIG. 5 is a perspective view of a piece member constituting the movable exterior member.

  As shown in FIGS. 4 and 5, the movable exterior member 40 constituting the movable region 35 includes a plurality of piece members 45, and these piece members 45 are connected to each other so as to be rotatable. The movable exterior member 40 constituted by these piece members 45 has two bent portions 46A and 46B bent in opposite directions. The bent portion 46A is restricted from bending in the same direction as the bent portion 46B, and the bent portion 46B is restricted from bending in the same direction as the bent portion 46A. For example, when the bending portions 46A and 46B are bent in the direction in which the stopper 45a is formed on the piece member 45 and bent in the direction to be restricted, the stopper 45a abuts on the adjacent piece member 45 and cannot be rotated. What should I do?

Next, the movement of the wire harness 10A when the luggage door 12 is opened and closed will be described.
6A and 6B are diagrams illustrating the movement of the opening / closing mechanism and the wire harness. FIG. 6A is a side view of the opening / closing mechanism when the luggage door is in a half-open state, and FIG. 6B is a view when the luggage door is in a half-open state. FIG. 7A and 7B are diagrams for explaining the movement of the opening / closing mechanism and the wire harness. FIG. 7A is a side view of the opening / closing mechanism when the luggage door is fully opened, and FIG. 7B is a view when the luggage door is fully opened. FIG.

  When the luggage door 12 is opened from the fully closed state (the state shown in FIGS. 1A and 1B) when the luggage door 12 is closed to the half-open state, as shown in FIGS. Rotates around the connection point with the bracket 15. As a result, the wire harness 10 </ b> A moves together with the luggage arm 16. Then, the arm fixing portion 42 of the movable region 35 moves away from the body fixing portion 41 while moving in an arc shape around the rotation center position of the luggage arm 16. Thereby, the movable region 35 is gradually extended, and the curvature radii of the respective bent portions 46A and 46B are increased. When the luggage door 12 is further opened from this state to a fully open state, as shown in FIGS. 7A and 7B, the position of the arm fixing portion 42 with respect to the body fixing portion 41 is separated to the maximum, thereby allowing the movable region to move. 35 is extended to such an extent that there is almost no bending at the bent portions 46A and 46B. Even in this fully open state, the bent portions 46A and 46B of the movable region 35 are slightly bent slightly.

  When the luggage door 12 is closed from the fully opened state, the arm fixing portion 42 moves in an arc shape around the rotation center position of the luggage arm 16 as the luggage arm 16 rotates, and approaches the body fixing portion 41. The bends of the bent portions 46A and 46B are gradually increased (see FIGS. 6A and 6B). Thereafter, when the luggage door 12 is fully closed, the position of the arm fixing portion 42 with respect to the body fixing portion 41 comes closest, and the movable region 35 has the smallest radius of curvature at the bent portions 46A and 46B. .

  Thus, according to the wiring structure of the wire harness 10 </ b> A according to the first embodiment, the movable region 35 of the wire harness 10 </ b> A that extends from the body 11 to the luggage arm 16 and is routed along the luggage arm 16. However, the movable region 35 is not twisted when the luggage arm 16 is rotated by opening and closing the luggage door 12 because the luggage door 12 is opened and closed. The rotation of the luggage arm 16 is followed. Therefore, it is possible to suppress the twisting force from being applied to the wire harness 10A, and it is possible to improve durability.

  In addition, the movable region 35 of the wire harness 10A that expands and contracts following the rotation of the luggage arm 16 has two bent portions 46A and 46B that are bent in opposite directions to each other. Is prevented from overhanging. Thereby, the space which accommodates the movable area | region 35 of 10 A of wire harnesses can be made as small as possible, and space saving can be achieved.

  In the first embodiment, the movable region 35 has a structure in which the wire bundle 32 is inserted into the movable exterior member 40 in which a plurality of piece members 45 are rotatably connected to each other, so that the luggage door 12 is opened and closed and the luggage arm is opened. When 16 is rotated, the piece members 45 of the movable exterior member 40 are rotated with respect to each other. As a result, the movable region 35 can smoothly follow the luggage arm 16.

Here, the routing structure according to Reference Example 1 will be described.
As shown in FIG. 8, in the wire harness 1 of the reference example 1, in order to suppress the load caused by the expansion and contraction of the wire harness 1 when the luggage door 12 is opened and closed, the load harness 16 is extended along the luggage arm 16 from the side. After mounting and fixing in the direction of arrow C in FIG. 8, in the vehicle width direction, an extra length portion 1 a is formed between the luggage arm 16 and the body 11 and wired in the air to the inner side surface 11 a of the body 11. It is attached and fixed from the side in the direction of arrow D in FIG. In the first reference example, a twisting force is applied to the extra length portion 1a of the wire harness 1 every time the luggage door 12 is opened and closed, which is problematic in terms of durability. Moreover, a large space for allowing the body 11 to pass the extra length 1a must be secured.

  On the other hand, according to the wiring structure of the wire harness according to the present embodiment, the power supply wire harness 20 connected to the connector 33 of the wire harness 10 </ b> A can be fixed along the inner surface of the body 11. Further space saving can be achieved (see FIG. 3).

(Second Embodiment)
Next, the wiring structure of the wire harness according to the second embodiment will be described. In addition, the same component as 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits description.
FIG. 9 is a side view of the opening / closing mechanism when the luggage door is in a fully closed state for explaining the wiring structure of the wire harness according to the second embodiment. FIG. 10 is a perspective view of the opening / closing mechanism when the luggage door is in a fully closed state for explaining the wiring structure of the wire harness according to the second embodiment. FIG. 11 is a front view of an opening / closing mechanism for explaining a wire harness routing structure according to the second embodiment. FIG. 12 is a cross-sectional view of the luggage arm of the opening / closing mechanism in which the wire harness is routed. FIG. 13 is a cross-sectional view of the wire harness. FIG. 14 is a view showing a wire harness having another structure, and FIGS. 14 (a) to 14 (d) are cross-sectional views, respectively. FIG. 15 is a perspective view of the opening / closing mechanism mounted with the wire harness with the arm cover removed.

  As shown in FIGS. 9 to 11, in the opening / closing mechanism 13 in which the wire harness 10 </ b> B is routed in the routing structure according to the second embodiment, the width of the arm cover 25 that covers the lower surface of the luggage arm 16 is narrow. Yes. As shown in FIG. 12, a gap between the lower surface of the luggage arm 16 and the bottom plate portion 26 of the arm cover 25 forms a harness housing space 28, and the wire harness 10 </ b> B is housed in the harness housing space 28. Thereby, the wire harness 10 </ b> B is disposed along the outer surface outside the rotation center of the luggage arm 16.

  As shown in FIG. 13, the wire harness 10B accommodated in the harness accommodating space 28 is formed in a flat shape. This wire harness 10B has an electric wire bundle 32 in which a plurality of electric wires 31 arranged in the width direction are stacked and bundled, and the periphery of the electric wire bundle 32 is covered with an outer sheath 51. In addition, a long resin-made plate member 52 having elasticity is provided inside the jacket 51, and the electric wires 31 are maintained in a state of being arranged in the width direction by the plate member 52. The plate member 52 is disposed on the side of the luggage arm 16 in the wire bundle 32.

  As shown in FIG. 14A, the wire harness 10B may be one in which a plurality of flat cables 31a in which the electric wires 31 are connected in parallel are stacked and covered with an outer jacket 51. As shown in (b), a plurality of flexible flat cables 31b integrated by sandwiching a wire 31 made of a flat conductor with a laminate film or the like may be laminated and covered with a jacket 51.

  Moreover, as shown in FIG.14 (c), as the wire harness 10B, without using the board member 52, the circumference | surroundings of the electric wire bundle 32 which piled up the row | line | column which arranged the some electric wire 31 in the width direction several times were bundled. What was covered with the jacket 51 may be used. Furthermore, as the wire harness 10B, as shown in FIG. 14 (d), a flat type having excellent stretchability is provided around the wire bundle 32 in which a plurality of rows of electric wires 31 arranged in the width direction are stacked and bundled. It may be covered with the tube 53 of the fiber mesh assembly. In particular, according to the structure using the fiber netting tube 53, when the wire harness 10B is bent, the fiber netting tube 53 spreads laterally, and the central portion in the width direction is pressed by the bending pressure. Therefore, the wire harness 10B is smoothly bent in a flat state. Moreover, since the tube 53 is in line contact with the electric wire 31, the friction is small and the load on the electric wire 31 can be reduced.

  As shown in FIGS. 9 and 15, the wire harness 10B is attached to the curved portion 17 of the luggage arm 16 from below toward the directions of arrows E, F, and G in FIG. These are fixed by a fixing member or bonded and fixed by an adhesive or an adhesive tape. The wire harness 10B has a movable region 55 between the arm fixing portion 54, which is a fixed portion to the luggage arm 16, and the connector 33. The movable region 55 is a link 21 formed in a U-shape. And passed through the spring member 22 and in the vicinity of the lower portion of the bracket 15.

  The movable region 55 of the wire harness 10B has two portions bent in opposite directions to each other with the inside of the link 21 and the spring member 22 passing through the U-shaped link 21 in a state where the luggage door 12 is closed. There are two bent portions 56A, 56B. In the movable region 55, the bent portions 56 </ b> A and 56 </ b> B are passed and held inside the link 21 and the spring member 22, so that the bent portion 56 </ b> A is restricted from bending in the same direction as the bent portion 56 </ b> B. In the portion 56B, bending in the same direction as the bending portion 56A is restricted.

Next, the movement of the wire harness 10B when the luggage door 12 is opened and closed will be described.
FIG. 16 is a side view of the opening / closing mechanism when the luggage door for explaining the movement of the opening / closing mechanism and the wire harness is in a half-open state. FIG. 17 is a side view of the opening / closing mechanism when the luggage door for explaining the movement of the opening / closing mechanism and the wire harness is fully opened.

  When the luggage door 12 is opened from the fully closed state (the state shown in FIG. 9) in which the luggage door 12 is closed to the half-open state, the luggage arm 16 is rotated around the connection point with the bracket 15 as shown in FIG. To do. Thereby, the wire harness 10 </ b> B moves together with the luggage arm 16. Then, the arm fixing portion 54 of the movable region 55 moves away from the end portion on the body 11 side while moving in an arc shape around the rotation center position of the luggage arm 16. Thereby, the movable region 55 is gradually extended, and the curvature radii of the respective bent portions 56A and 56B are increased. When the luggage door 12 is further opened from this state to a fully open state, as shown in FIG. 17, the position of the arm fixing portion 54 with respect to the end portion on the body 11 side is separated to the maximum, thereby the movable region 55 is bent. The portions 56A and 56B are extended to such an extent that there is almost no bending. Even in this fully open state, the bent portions 56A and 56B of the movable region 55 are slightly bent gently.

  When the luggage door 12 is closed from this fully opened state, the arm fixing portion 54 moves in an arc shape around the rotation center position of the luggage arm 16 as the luggage arm 16 rotates, and moves toward the end on the body 11 side. The bends of the bent portions 56A and 56B gradually increase (see FIG. 16). Thereafter, when the luggage door 12 is fully closed, the position of the arm fixing portion 54 with respect to the end portion on the body 11 side comes closest, and the movable region 55 has the smallest radius of curvature at the bent portions 56A and 56B. (See FIG. 9).

  Here, as shown in FIG. 18, if the movable region 55 of the wire harness 10B is not passed inside the link 21 and the spring member 22, when the luggage door 12 is closed, the movable region 55 of the wire harness 10B is It may bulge out and interfere with surrounding members.

  On the other hand, in this embodiment, the movable region 55 of the wire harness 10B is inserted into the inside of the link 21 and the spring member 22 formed in a U-shape, and at a position close to the luggage arm 16 at this insertion point. It is in a retained state. Therefore, when the luggage door 12 is closed, the movable region 55 is guided to be bent in a predetermined direction by the bent portions 56A and 56B. That is, the bending portion 56A is restricted from bending in the same direction as the bending portion 56B, which is opposite to the bending direction, and the bending portion 56B is bent in the same direction as the bending portion 56A, which is opposite to the bending direction. Is regulated.

  As described above, also in the case of the wiring structure of the wire harness 10B according to the second embodiment, the wire harness 10B extending from the body 11 to the luggage arm 16 and routed along the luggage arm 16 can be used. Since the movable region 55 is disposed along a direction orthogonal to the rotation axis of the luggage arm 16, the movable region 55 is twisted when the luggage arm 16 is rotated by opening and closing the luggage door 12. It follows the rotation of the luggage arm 16 without being moved. Therefore, it is possible to suppress the twisting force from being applied to the wire harness 10B, and it is possible to improve durability.

  Further, the movable region 55 of the wire harness 10B that is expanded and contracted following the rotation of the luggage arm 16 has two bent portions 56A and 56B that are bent in opposite directions to each other. Is prevented from overhanging. Thereby, the space which accommodates the movable area | region 55 of the wire harness 10B can be made as small as possible, and space saving can be achieved.

  In addition, since the movable region 55 is formed in a flat shape in cross section and is disposed along the direction perpendicular to the bending direction of the bent portions 56A and 56B, the luggage door 12 is opened and closed and the luggage arm 16 is rotated. When moved, the movable region 55 having a flat cross-sectional shape is smoothly deformed in the thickness direction. As a result, the movable region 55 can smoothly follow the luggage arm 16.

  In the second embodiment, the movable region 55 is disposed at the same position in the rotation axis direction of the luggage arm 16, and the luggage arm 16 and the movable region 55 of the wire harness 10 </ b> B are orthogonal to the rotation axis of the luggage arm 16. It is stacked in the direction. Accordingly, as shown in FIG. 19, further space saving can be achieved with respect to the structure in which the wire harness 1 is placed along the side of the luggage arm 16.

  Also in the case of the wire harness 10B according to the second embodiment, the power supply wire harness 20 connected to the connector 33 of the wire harness 10B can be fixed along the inner surface of the body 11. Specifically, the wire harness 20 is attached to the body 11 from below in the direction of the arrow H in FIG. 11, and from the side to the inner side surface 11a of the body 11, the direction of the arrow I in FIG. Can be attached to the head and fixed with a fixing member such as a screw, a clamp or the like, or can be adhered and bonded with an adhesive or an adhesive tape, thereby further saving space (see FIG. 11).

(Third embodiment)
Next, the wiring structure of the wire harness according to the third embodiment, which is a modification of the second embodiment, will be described.

  FIG. 20 is a perspective view of the opening / closing mechanism when the luggage door is in a fully closed state for explaining the wiring structure of the wire harness according to the third embodiment. FIG. 21 is a view showing the opening / closing mechanism and the wire harness when the luggage door is in the fully closed state, in which FIG. 21 (a) is a side view and FIG. 21 (b) is a perspective view.

  As shown in FIGS. 20 and 21 (a) and 21 (b), also in the routing structure according to the third embodiment, the wire harness 10B formed in a flat shape on the opening / closing mechanism 13 as in the second embodiment. (See FIG. 13 and FIG. 14). An arm cover 25 is attached to the luggage arm 16 of the opening / closing mechanism 13 from below, and the wire harness 10B is housed in a harness housing space 28 formed by a gap between the lower surface of the luggage arm 16 and the bottom plate portion 26 of the arm cover 25. Has been. Thereby, the wire harness 10 </ b> B is disposed along the outer surface outside the rotation center of the luggage arm 16.

  The arm cover 25 attached to the lower surface of the luggage arm 16 has a protection part 29. The protection part 29 is composed of a pair of side plates 29 a that project to the front side of the luggage arm 16 with the luggage door 12 closed. The connector 33 provided at one end of the wire harness 10 </ b> B is disposed on the side of the protection unit 29 with the luggage door 12 closed.

  The wire harness 10 </ b> B is disposed between the side plates 29 a of the protection part 29 of the arm cover 25 in a state in which a part of the movable region 55 is closed. Accordingly, both sides of the movable region 55 having the two bent portions 56 </ b> A and 56 </ b> B of the wire harness 10 are covered and protected by the side plates 29 a of the protection portion 29 of the arm cover 25.

  The luggage arm 16 to which the arm cover 25 is attached is covered with a trim 31 provided on the lower side of the curved portion 17 along the inner wall of the luggage space. In the state in which the luggage door 12 is closed, the luggage arm 16 is pulled out into the luggage from an opening formed in the trim 31 with a fixing portion 19 on the other end side fixed to the luggage door 12.

  Next, the movement of the wire harness 10B when the luggage door 12 is opened and closed will be described.

  22A and 22B are diagrams showing an opening / closing mechanism and a wire harness when the luggage door is in a half-open state, in which FIG. 22A is a side view and FIG. 22B is a perspective view. FIG. 23 is a view showing an opening / closing mechanism and a wire harness when the luggage door is in a fully opened state, in which FIG. 23 (a) is a side view and FIG. 23 (b) is a perspective view.

  When the luggage door 12 is opened from the fully closed state (the state shown in FIGS. 21A and 21B) when the luggage door 12 is closed to the half-open state, as shown in FIGS. Rotates around the connection point with the bracket 15. Thereby, the wire harness 10 </ b> B moves together with the luggage arm 16. Then, the arm fixing portion 54 of the movable region 55 moves away from the end portion on the body 11 side while moving in an arc shape around the rotation center position of the luggage arm 16. Thereby, the movable region 55 is gradually extended, and the curvature radii of the respective bent portions 56A and 56B are increased.

  When the luggage door 12 is further opened from this state and is fully opened, as shown in FIGS. 23 (a) and 23 (b), the position of the arm fixing portion 54 with respect to the end portion on the body 11 side is separated to the maximum. The movable region 55 is extended to such an extent that bending at the bent portions 56A and 56B is almost eliminated. Even in this fully open state, the bent portions 56A and 56B of the movable region 55 are slightly bent gently.

  When the luggage door 12 is closed from this fully opened state, the arm fixing portion 54 moves in an arc shape around the rotation center position of the luggage arm 16 as the luggage arm 16 rotates, and moves toward the end on the body 11 side. The bends of the bent portions 56A and 56B gradually increase (see FIGS. 22A and 22B). Thereafter, when the luggage door 12 is fully closed, the position of the arm fixing portion 54 with respect to the end portion on the body 11 side comes closest, and the movable region 55 has the smallest radius of curvature at the bent portions 56A and 56B. (See FIGS. 21A and 21B).

  When the luggage door 12 is closed, the arm cover 25 is also rotated in the reverse direction as the luggage arm 16 is rotated in the reverse direction. Then, the protection part 29 of the arm cover 25 that has been moved to the lower side of the luggage arm 16 moves to the front side of the luggage arm 16, and a part of both sides in the movable region 55 of the wire harness 10 is a side plate of the protection part 29. 29a.

  During the opening / closing operation of the luggage door 12, the movable region 55 of the wire harness 10 </ b> B is guided while being protected by the pair of side plates 29 a of the protection unit 29 of the arm cover 25. Therefore, the movable region 55 is deformed in a stable posture while suppressing interference with surrounding members and the like.

  Moreover, the protection part 29 that projects to the front of the arm cover 25 is formed so as to cover a part of both sides of the movable region 55 of the wire harness 10B with the luggage door 12 closed. Therefore, compared with the structure which covers the whole circumference | surroundings of the movable area | region 55 of the wire harness 10B in the state which closed the luggage door 12, the magnitude | size which protrudes can be made small as much as possible. Thereby, the turning radius of the protection part 29 when the luggage door 12 is opened and closed can be reduced, and interference with the trim 31 provided along the inner wall of the luggage space can be prevented (see FIGS. 21 to 23). . Thereby, the accommodation space of the luggage arm 16 in the back side of the trim 31 can be reduced, and the luggage space can be expanded.

  In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimensions, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

  For example, in the above embodiment, the luggage door 12 is exemplified as the door that is opened and closed with respect to the body 11. However, in the present invention, the wire harnesses 10 </ b> A and 10 </ b> B are routed to the opening / closing portion of the door other than the luggage door 12.
