Wiring harness routing structure, link type sliding door, and wiring harness
View Patent ↗A wiring harness routing structure includes at least a sub-link arm and a routed line. The sub-link arm includes one end that is rotatably coupled to a vehicle body by using a first coupler, and another end that is rotatably coupled to a door body by using a second coupler, and slidably supports the door body relative to the vehicle body, while rotationally moving relative to each of the vehicle body and the door body. A routed line is routed and provided along the sub-link arm, and connects a vehicle-body-side connector and a door-side connector. In addition, the routed line is routed through a lower side in a height direction of the first coupler that is coupled to the sub-link arm, in a state where the door body has slid to be fully opened.

the routed line is routed on the lower side of the projecting support in the vertical direction.
6. The wiring harness routing structure according to claim 2 , wherein
the vehicle body includes a vehicle body frame that forms a framework of the vehicle body, and a projecting support that is provided to project from the vehicle body frame to a vehicle cabin side, and supports the vehicle-body-side coupler, and
the routed line is routed on the lower side of the projecting support in the vertical direction.
7. The wiring harness routing structure according to claim 3 , wherein
the vehicle body includes a vehicle body frame that forms a framework of the vehicle body, and a projecting support that is provided to project from the vehicle body frame to a vehicle cabin side, and supports the vehicle-body-side coupler, and
the routed line is routed on the lower side of the projecting support in the vertical direction.
8. The wiring harness routing structure according to claim 1 , wherein
the link arm includes a groove that is formed in a groove shape along an extending direction in which the link arm extends, the groove enabling the routed line to be housed, and
the routed line is routed in a state where the routed line is housed in the groove.
9. The wiring harness routing structure according to claim 2 , wherein
the link arm includes a groove that is formed in a groove shape along an extending direction in which the link arm extends, the groove enabling the routed line to be housed, and
the routed line is routed in a state where the routed line is housed in the groove.
10. The wiring harness routing structure according to claim 3 , wherein
the link arm includes a groove that is formed in a groove shape along an extending direction in which the link arm extends, the groove enabling the routed line to be housed, and
the routed line is routed in a state where the routed line is housed in the groove.
11. The wiring harness routing structure according to claim 5 , wherein
the link arm includes a groove that is formed in a groove shape along an extending direction in which the link arm extends, the groove enabling the routed line to be housed, and
the routed line is routed in a state where the routed line is housed in the groove.
12. A link type sliding door comprising:
a door body that is mounted on a vehicle body;
a link arm extending in a horizontal direction and including one end that is rotatably coupled to the vehicle body by using a vehicle-body-side coupler, and another end that is rotatably coupled to the door body by using a door-side coupler, the link arm slidably supporting the door body relative to the vehicle body, while rotationally moving relative to each of the vehicle body and the door body; and
a routed line that is routed and provided along the link arm, and connects a connection target on a side of the vehicle body and the connection target on a side of the door body, wherein
the link arm comprises:
a first cut-away portion on a lower side wall of the link arm extending in a horizontal direction and being a first opening of the lower side wall of the link arm; and
a second cut-away portion on an upper side wall of the link arm extending in the horizontal direction and being a second opening of the upper side wall of the link arm,
the routed line is routed from an outside on a lower side of the vehicle-body-side coupler to the link arm in a vertical direction through the first cut-away portion and from the link arm to the outside on an upper side of the door-side coupler in the vertical direction through the second cut-away portion, in a state where the door body has slid to be fully opened.
