A harness body ( 10 ) is guided to a fixed portion ( 522 ) on a side of a slide door ( 520 ) by a harness guide tool ( 40 ) at an other end portion ( 612 ) of a first arm member ( 610 ) on a side of a vehicle body ( 510 ) and includes a third routing portion ( 13 ) having a fixing portion ( 13 a ) fixed to the fixed portion, a link mechanism ( 600 ) includes a second arm member ( 620 ) on the side of the slide door coupled to the other end portion of the first arm member via a second rotation shaft ( 641 ), and the third routing portion is twisted and deformed about its own axis between the harness guide tool and the fixing portion when the first arm member and the second arm member are relatively rotated with respect to each other.
1. A wire harness comprising:
a harness body having a first routing portion routed in a link mechanism that couples a vehicle body and a slide door and reciprocates the slide door in a sliding direction with respect to the vehicle body, a second routing portion routed closer to a side of the vehicle body than the first routing portion, and a third routing portion routed closer to a side of the slide door than the first routing portion;
a harness fixing tool that fixes a fixing portion of the third routing portion to a fixed portion on the side of the slide door provided not to cause relative displacement with respect to the slide door; and
a harness guide tool that regulates a routing path of the third routing portion, wherein
the link mechanism includes a first arm member having one end portion coupled to the side of the vehicle body and the first routing portion routed to an other end portion, a second arm member having one end portion connected to the side of the slide door, a first rotation shaft having a direction orthogonal to the sliding direction as an axial direction and capable of first relative rotation between the vehicle body and the one end portion of the first arm member, a second rotation shaft parallel to the first rotation shaft and capable of second relative rotation between the other end portion of the first arm member to which the harness guide tool is fixed and an other end portion of the second arm member, and a third rotation shaft parallel to the first rotation shaft and the second rotation shaft and capable of third relative rotation between the slide door and the one end portion of the second arm member, in which the slide door reciprocates in the sliding direction with respect to the vehicle body along a plane orthogonal to the first rotation shaft, the second rotation shaft, and the third rotation shaft,
the harness guide tool guides the third routing portion toward the fixed portion on the side of the slide door positioned in a direction intersecting the orthogonal plane with respect to the harness guide tool, and
the third routing portion is bent and deformed between the harness guide tool and the fixing portion when the second arm member is relatively rotated about an axis of the third rotation shaft with respect to the slide door, and is twisted and deformed about its own axis between the harness guide tool and the fixing portion when the first arm member and the second arm member are relatively rotated about an axis of the second rotation shaft with respect to each other.
2. The wire harness according to claim 1 , wherein
the fixed portion on the side of the slide door is provided in an area on an upper side of a vehicle or an area on a lower side of a vehicle with respect to the harness guide tool.
3. The wire harness according to claim 1 , wherein
the link mechanism relatively rotates the second arm member about the axis of the third rotation shaft with respect to the slide door within a swing width range, and
the link mechanism, when moving the slide door at a fully closed position to a fully opened position, relatively rotates the first arm member about an axis of the first rotation shaft with respect to the vehicle body, and relatively rotates the second arm member positioned at one end of the swing width with respect to the slide door about the axis of the third rotation shaft with respect to the slide door while relatively rotating the second arm member about the axis of the second rotation shaft with respect to the first arm member in a manner that the second arm member reaches the other end of the swing width with respect to the slide door, and relatively rotates the first arm member about the axis of the second rotation shaft with respect to the second arm member while continuing the relative rotation of the first arm member about the axis of the first rotation shaft with respect to the vehicle body and keeping the second arm member positioned at the other end of the swing width respect to the slide door.
4. The wire harness according to claim 2 , wherein
the link mechanism relatively rotates the second arm member about the axis of the third rotation shaft with respect to the slide door within a swing width range, and
the link mechanism, when moving the slide door at a fully closed position to a fully opened position, relatively rotates the first arm member about an axis of the first rotation shaft with respect to the vehicle body, and relatively rotates the second arm member positioned at one end of the swing width with respect to the slide door about the axis of the third rotation shaft with respect to the slide door while relatively rotating the second arm member about the axis of the second rotation shaft with respect to the first arm member in a manner that the second arm member reaches the other end of the swing width with respect to the slide door, and relatively rotates the first arm member about the axis of the second rotation shaft with respect to the second arm member while continuing the relative rotation of the first arm member about the axis of the first rotation shaft with respect to the vehicle body and keeping the second arm member positioned at the other end of the swing width respect to the slide door.
