1. A wire harness comprising:
a first protector disposed in a fixed first link;
a second protector disposed in a second link relatively rotatable with respect to the first link; and
a flexible tubular exterior member including a first end portion fixed to the first protector and a second end portion fixed to the second protector; and
an electric wire inserted through each of the first protector, the second protector, and the exterior member and routed to the second link; wherein
the second link includes a base located at one end in a longitudinal direction, and the base is supported by the first link via a rotating shaft such that the second link is relatively rotatable with respect to the first link centering on the base,
the first protector includes a first tubular section opened toward the rotating shaft,
the first end portion of the exterior member is fixed to the first tubular section, and
the exterior member extends and contracts according to a change in a line length between the first protector and the second protector caused by relative rotation of the second link with respect to the first link.
