Wire harness

A wire harness comprising:

• a harness body that includes a first routed portion routed in a link mechanism that couples a first coupling target and a second coupling target, a second routed portion routed on the first coupling target side with respect to the first routed portion, and a third routed portion routed on the second coupling target side with respect to the first routed portion;
• a harness fixing tool that fixes a fixing portion of the third routed portion to a fixed portion on the second coupling target side provided so as not to cause relative displacement with respect to the second coupling target;
• and
• a harness guide tool that restricts a routing path of the third routed portion, wherein
• the link mechanism includes a first arm member having one end portion coupled to the first coupling target side and an other end portion at which the first routed portion is routed, a second arm member having one end portion coupled to the second coupling target side, a first rotation shaft that enables relative rotation between the first coupling target and the one end portion of the first arm member, a second rotation shaft that is parallel to the first rotation shaft and enables 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 that is parallel to the first rotation shaft and the second rotation shaft and enables relative rotation between the second coupling target and the one end portion of the second arm member, and enables relative displacement between the first coupling target and the second coupling target along an orthogonal plane with respect to the first rotation shaft, the second rotation shaft, and the third rotation shaft,
• the harness guide tool guides the third routed portion toward the fixed portion on the second coupling target side located in a direction intersecting the orthogonal plane with respect to the harness guide tool, and
• the third routed 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 second coupling target.
