[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a wire harness according to the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to these embodiments.

[0010] [Embodiment] One embodiment of a wire harness according to the present invention will be described with reference to FIGS. 1 to 8. FIG.

[0011] Reference numeral 1 in FIGS. 1 to 6 indicates a wire harness according to this embodiment. This wire harness 1 is mounted on a vehicle such as an automobile equipped with a sliding door, and is responsible for supplying power from a power source (such as a secondary battery) on the vehicle body side to an electrically connected object on the sliding door side. The electrically connected object is something that is installed on the sliding door, such as an electrical component or a switch. For example, the electrical component of the sliding door refers to a drive device for driving a power window, a speaker, etc. Furthermore, the switch of the sliding door refers to a switch for operating a power window, a switch for operating a power seat, etc.

[0012] The wire harness 1 includes an electric wire 10, one end of which is electrically connected directly or indirectly to a power source on the vehicle body side, and the other end of which is electrically connected directly or indirectly to an object to be electrically connected on the sliding door side. The electric wire 10 has a bridge portion 10A that is a portion between the one end and the other end and that spans between the vehicle body and the sliding door (FIGS. 1, 2, 5, and 6). In the bridge portion 10A, the electric wire 10 is covered, for example, with a cylindrical corrugated tube (not shown).

[0013] In this electric wire 10, one end on the vehicle body side exists beyond one end of the crossover portion 10A (hereinafter referred to as the "vehicle body side end"), and the other end on the sliding door side exists beyond the other end of the crossover portion 10A (hereinafter referred to as the "door side end"). Thus, the electric wire 10 has a vehicle body side routing portion 10B (FIG. 5) routed beyond the vehicle body side end of the crossover portion 10A, and a door side routing portion 10C (FIG. 6) routed beyond the door side end of the crossover portion 10A.

[0014] In the electric wire 10, the vehicle body side end of the crossover portion 10A is assembled to the vehicle body side. The wire harness 1 is fixed to the vehicle body and includes a vehicle body side unit 20 to which the vehicle body side end of the crossover portion 10A is assembled (FIGS. 1 to 3 and 5). In other words, the vehicle body side end of the crossover portion 10A is assembled to the vehicle body side via this vehicle body side unit 20.

[0015] The vehicle body side unit 20 includes a cylindrical body rotor 30 that accommodates the vehicle body side end of the transition portion 10A within the cylinder, and a body protector 40 that is fixed to the vehicle body and rotates the body rotor 30 relatively around the axis of one end 30a (FIGS. 1 to 3 and 5). The body rotor 30 and the body protector 40 are molded from an insulating material such as synthetic resin. The vehicle body side unit 20 causes the vehicle body side routing portion 10B of the electric wire 10, which is pulled out from an opening at one end 30a of the body rotor 30, to be pulled out toward the vehicle body.

[0016] The body rotor 30 has a vehicle body-side end 30a at one end 30a of the body rotor 30. The body rotor 30 extends the transition portion 10A through the cylinder and is pulled out from an opening at the other end 30b of the body rotor 30 on the sliding door side (FIGS. 1, 2, and 5). The body rotor 30 supports the transition portion 10A at the other end 30b, for example.

[0017] The body protector 40 rotatably supports one end 30a of the body rotor 30, and rotates the body rotor 30 about a vertically extending rotation shaft (hereinafter referred to as the "vehicle body rotation shaft") 31 in conjunction with the opening and closing of the sliding door (FIGS. 1, 2, and 5). In the vehicle body unit 20, the vehicle body rotation shaft 31 is provided at one end 30a of the body rotor 30, and a bearing 41 for the vehicle body rotation shaft 31 is provided in the body protector 40 (FIG. 5).

[0018] For example, the body rotor 30 shown here comprises a first body rotor member 30A and a second body rotor member 30B that are divided along the cylinder axis and assembled together (FIGS. 1 to 3 and 5). The first body rotor member 30A is disposed vertically below the transition portion 10A within the cylinder of the body rotor 30. The second body rotor member 30B is disposed vertically above the transition portion 10A within the cylinder of the body rotor 30.

[0019] Here, the first body rotor member 30A has a bottom portion 32a extending vertically downward along the cylindrical axis and a pair of side wall portions 32b extending vertically upward from a pair of ends of the bottom portion 32a extending along the cylindrical axis (FIG. 5). The second body rotor member 30B has a top portion 33a extending vertically upward along the cylindrical axis and a pair of side wall portions 33b extending vertically downward from a pair of ends of the top portion 33a extending along the cylindrical axis (FIG. 5). The body rotor 30 shown here has a double-wall structure in which the pair of side wall portions 32b of the first body rotor member 30A are externally covered by the pair of side wall portions 33b of the second body rotor member 30B in the assembled state, and this pair of double walls increases rigidity.

[0020] In this body rotor 30, vehicle body side rotating shafts 31 are coaxially suspended from the outer wall surface of the bottom portion 32a of the first body rotor member 30A and the outer wall surface of the top portion 33a of the second body rotor member 30B.

[0021] The body rotor 30 maintains the first body rotor member 30A and the second body rotor member 30B in the assembled state by engaging the first engagement portion 32c provided on the first body rotor member 30A with the second engagement portion 33c provided on the second body rotor member 30B in the assembled state (FIG. 5). A plurality of first engagement portions 32c are provided on each side wall portion 32b. A plurality of second engagement portions 33c are also provided on each side wall portion 33b. For example, in this example, in the assembled state, the claw-shaped first engagement portions 32c are hooked onto the second engagement portions 33c, thereby engaging them with each other.

[0022] The body rotor 30 has a main body 34 at one end 30a thereof that rotates inside the body protector 40, and an extension 35 that extends from the main body 34 toward the other end 30b thereof outside the body protector 40 (FIGS. 1, 2, and 5). The body rotor 30 shown here is broadly divided into the main body 34 and the extension 35, and the vehicle body side routing portion 10B of the electric wire 10 is led out from an opening at one end 30a of the main body 34, and the crossover portion 10A is led out from an opening at the other end 30b of the extension 35.

[0023] The body protector 40 has an internal space in which the main body 34 of the body rotor 30 is disposed. The vehicle body side wiring portion 10B of the electric wire 10 is pulled out from an opening at one end 30a of the main body 34, routed through the internal space of the body protector 40, and pulled out to the outside of the body protector 40.

[0024] This body protector 40 includes a first body protector member 40A that covers the body rotor 30 from below vertically and supports one end of the vehicle body rotating shaft 31, and a second body protector member 40B that covers the body rotor 30 from above vertically and supports the other end of the vehicle body rotating shaft 31 (FIGS. 1 to 3 and 5). The body protector 40 shown here covers the first body rotor member 30A from below vertically with the first body protector member 40A, and covers the second body rotor member 30B from above vertically with the second body protector member 40B.

[0025] The first body protector member 40A has a bottom portion 42a that covers the bottom portion 32a of the first body rotor member 30A from below in the vertical direction, and a pair of side wall portions 42b that are aligned along the routing path of the vehicle-body-side routing portion 10B of the electric wire 10 in the internal space of the body protector 40 (FIG. 5). The second body protector member 40B has a top portion 43a that covers the top portion 33a of the second body rotor member 30B from above in the vertical direction, and a pair of side wall portions 43b that are aligned along the routing path of the vehicle-body-side routing portion 10B of the electric wire 10 in the internal space of the body protector 40 (FIG. 5).

[0026] In this body protector 40, a bearing 41 supporting the vehicle body side rotating shaft 31 of the first body rotor member 30A is provided on the inner wall surface of the bottom 42a of the first body protector member 40A, and a bearing 41 supporting the vehicle body side rotating shaft 31 of the second body rotor member 30B is provided on the inner wall surface of the top portion 43a of the second body protector member 40B.

[0027] The body protector 40 maintains the first body protector member 40A and the second body protector member 40B in the assembled state by engaging the first engagement portion 42c provided on the first body protector member 40A and the second engagement portion 43c provided on the second body protector member 40B with each other in the assembled state (FIG. 5). A plurality of first engagement portions 42c are provided on each side wall portion 42b. A plurality of second engagement portions 43c are also provided on each side wall portion 43b. For example, in this example, the claw-shaped second engagement portions 43c are hooked onto the first engagement portions 42c in the assembled state, thereby engaging them with each other.

[0028] In addition, in the electric wire 10, the door side end of the crossover portion 10A is assembled to the sliding door side. The wire harness 1 is fixed to the sliding door and includes a door side unit 50 to which the door side end of the crossover portion 10A is assembled (FIGS. 1, 2, 4, and 6). That is, the door side end of the crossover portion 10A is assembled to the sliding door side via this door side unit 50.

[0029] The door-side unit 50 includes a cylindrical door rotor 60 that accommodates the door-side end of the transition portion 10A inside the cylinder, and a door protector 70 that is fixed to the sliding door and rotates the door rotor 60 relatively around the axis of one end 60a (FIGS. 1, 2, 4, and 6). The door rotor 60 and the door protector 70 are molded from an insulating material such as synthetic resin. The door-side unit 50 pulls the door-side wiring portion 10C of the electric wire 10, which is pulled out from the opening at one end 60a of the door rotor 60, toward the sliding door.

[0030] In the door rotor 60, the door-side end of the transition portion 10A is disposed at one end 60a on the sliding door side within the cylinder. The transition portion 10A passes through the cylinder of the door rotor 60 and is pulled out from an opening at the other end 60b on the vehicle body side (FIGS. 1, 2, and 6). The door rotor 60 supports the transition portion 10A at, for example, the other end 60b.

[0031] The door protector 70 rotatably supports one end 60a of the door rotor 60, and rotates the door rotor 60 about a rotation shaft (hereinafter referred to as the "door-side rotation shaft") 61 extending vertically in conjunction with the opening and closing of the sliding door (FIGS. 1, 2, and 6). In the door-side unit 50, the door-side rotation shaft 61 is provided at one end 60a of the door rotor 60, and a bearing 71 for the door-side rotation shaft 61 is provided in the door protector 70 (FIG. 6).

[0032] For example, the door rotor 60 shown here comprises a first door rotor member 60A and a second door rotor member 60B that are divided along the cylindrical axis and assembled together (FIGS. 1, 2, 4, and 6). The first door rotor member 60A is disposed vertically below the crossover portion 10A inside the cylindrical door rotor 60. The second door rotor member 60B is disposed vertically above the crossover portion 10A inside the cylindrical door rotor 60.

[0033] Here, the first door rotor member 60A has a bottom portion 62a extending vertically downward along the cylindrical axis and a pair of side walls 62b extending vertically upward from a pair of ends of the bottom portion 62a extending along the cylindrical axis (FIG. 6). The second door rotor member 60B has a top portion 63a extending vertically upward along the cylindrical axis and a pair of side walls 63b extending vertically downward from a pair of ends of the top portion 63a extending along the cylindrical axis (FIG. 6). The door rotor 60 shown here has a double-wall structure in which the pair of side walls 62b of the first door rotor member 60A are externally covered by the pair of side walls 63b of the second door rotor member 60B in the assembled state, and this pair of double walls increases rigidity.

[0034] In this door rotor 60, door-side rotation shafts 61 are coaxially suspended from the outer wall surface of the bottom portion 62a of the first door rotor member 60A and the outer wall surface of the top portion 63a of the second door rotor member 60B.

[0035] The door rotor 60 maintains the first door rotor member 60A and the second door rotor member 60B in the assembled state by engaging the first engagement portion 62c provided on the first door rotor member 60A and the second engagement portion 63c provided on the second door rotor member 60B with each other in the assembled state (FIG. 6). A plurality of first engagement portions 62c are provided on each side wall portion 62b. A plurality of second engagement portions 63c are also provided on each side wall portion 63b. For example, in this example, in the assembled state, the claw-shaped first engagement portions 62c are hooked onto the second engagement portions 63c, thereby engaging them with each other.

[0036] The door protector 70 has an internal space, in which one end 60a of the door rotor 60 is disposed, with the other end 60b of the door rotor 60 protruding from the internal space. Thus, the opening at the one end 60a of the door rotor 60 is disposed in the internal space of the door protector 70. The door-side routing portion 10C of the electric wire 10 is pulled out from the opening at the one end 60a, routed through the internal space of the door protector 70, and pulled out to the outside of the door protector 70.

[0037] This door protector 70 includes a first door protector member 70A that covers the door rotor 60 from vertically below and supports one end of the door-side rotating shaft 61, and a second door protector member 70B that covers the door rotor 60 from vertically above and supports the other end of the door-side rotating shaft 61 (FIGS. 1, 2, 4, and 6). The door protector 70 shown here covers the first door rotor member 60A from vertically below with the first door protector member 70A, and covers the second door rotor member 60B from vertically above with the second door protector member 70B.

[0038] The first door protector member 70A has a bottom portion 72a that vertically covers the bottom portion 62a of the first door rotor member 60A from below, and a pair of side wall portions 72b that are aligned along the routing path of the door-side routing portion 10C of the electric wire 10 in the internal space of the door protector 70 (FIG. 6). The second door protector member 70B has a top portion 73a that vertically covers the top portion 63a of the second door rotor member 60B from above, and a pair of side wall portions 73b that are aligned along the routing path of the door-side routing portion 10C of the electric wire 10 in the internal space of the door protector 70 (FIG. 6).

[0039] In this door protector 70, a bearing 71 that supports the door side rotating shaft 61 of the first door rotor member 60A is provided on the inner wall surface of the bottom 72a of the first door protector member 70A, and a bearing 71 that supports the door side rotating shaft 61 of the second door rotor member 60B is provided on the inner wall surface of the top 73a of the second door protector member 70B.

[0040] The door protector 70 maintains the first and second door protector members 70A and 70B in the assembled state by engaging the first engagement portion 72c provided on the first door protector member 70A and the second engagement portion 73c provided on the second door protector member 70B with each other in the assembled state (FIG. 6). A plurality of first engagement portions 72c are provided on each side wall portion 72b. A plurality of second engagement portions 73c are provided on each side wall portion 73b. For example, in this example, the claw-shaped second engagement portions 73c are hooked onto the first engagement portions 72c in the assembled state, thereby engaging them with each other.

[0041] In the wire harness 1, the body protector 40 rotatably holds the body rotor 30, suppressing any vertical rattle between them. Also, in the wire harness 1, the door protector 70 rotatably holds the door rotor 60, suppressing any vertical rattle between them. These features in the wire harness 1 suppress the generation of abnormal noise caused by external inputs such as road inputs while driving.

[0042] Therefore, a vehicle-body-side elastic portion is provided on either the body rotor 30 or the second body protector member 40B, which is sandwiched between the other and compresses and deforms vertically, eliminating the gap between the body rotor 30 and the first body protector member 40A with the elastic force resulting from the compressive deformation. A door-side elastic portion is provided on either the door rotor 60 or the second door protector member 70B, which is sandwiched between the other and compresses and deforms vertically, eliminating the gap between the door rotor 60 and the first door protector member 70A with the elastic force resulting from the compressive deformation. For example, the vehicle-body-side elastic portion is formed in a double-supported beam shape with its center curved convexly toward the other of the body rotor 30 and the second body protector member 40B. The door-side elastic portion is also formed in a double-supported beam shape with its center curved convexly toward the other of the door rotor 60 and the second door protector member 70B.

[0043] In this example, the second body rotor member 30B of the body rotor 30 is provided with a vehicle-body-side elastic portion 36 having a beam-like shape, and the center of this vehicle-body-side elastic portion 36 is curved convexly toward the second body protector member 40B (FIGS. 3, 5, and 7). Also, in this example, the second door rotor member 60B of the door rotor 60 is provided with a door-side elastic portion 66 having a beam-like shape, and the center of this door-side elastic portion 66 is curved convexly toward the second door protector member 70B (FIGS. 4, 6, and 8).

[0044] The vehicle-body-side elastic portion 36 has a contact portion 36a at its center that bulges out hemispherically toward the second body protector member 40B (FIG. 7). The vehicle-body-side elastic portion 36 has this contact portion 36a to reduce frictional resistance when the body rotor 30 is rotated around the vehicle-body-side rotating shaft 31. The door-side elastic portion 66 has a contact portion 66a at its center that bulges out hemispherically toward the second door protector member 70B (FIG. 8). The door-side elastic portion 66 has this contact portion 66a to reduce frictional resistance when the door rotor 60 is rotated around the door-side rotating shaft 61.

[0045] In the vehicle-body-side unit 20, the body rotor 30 is rotatably sandwiched by the body protector 40 via the vehicle-body-side elastic portion 36, thereby suppressing rattle between the body rotor 30 and the body protector 40 in the vertical direction (axial direction of the vehicle-body-side rotating shaft 31), thereby suppressing the generation of abnormal noise between the body rotor 30 and the door protector 70 via the door-side elastic portion 66, thereby suppressing rattle between the body rotor 30 and the door protector 70 in the vertical direction (axial direction of the door-side rotating shaft 61), thereby suppressing the generation of abnormal noise ... door-side elastic portion 66, thereby suppressing the generation of abnormal noise between the body rotor 30 and the door protector 70 in the vertical direction (axial direction of the door-side rotating shaft 61), thereby suppressing the generation of abnormal noise between the body rotor 30 and the door protector 70 in the door-side elastic portion 66. In this way, the wire harness 1 of this embodiment can suppress the generation of abnormal noise during driving.

[0046] Furthermore, in the vehicle-body-side unit 20, the vehicle-body-side elastic portion 36 is interposed between the body rotor 30 and the body protector 40, so that even if an external force is applied to the body protector 40, the force can be absorbed by the vehicle-body-side elastic portion 36, thereby maintaining quality. Also, in the door-side unit 50, the door-side elastic portion 66 is interposed between the door rotor 60 and the door protector 70, so that even if an external force is applied to the door protector 70, the force can be absorbed by the door-side elastic portion 66, thereby maintaining quality. In this way, the durability of the wire harness 1 of this embodiment can be improved. [Explanation of symbols]
