Harness routing structure for link

1. A harness routing structure, comprising:

a supporting portion having a first fixing portion for fixing a wire harness, the supporting portion having a shaft portion;

a link pivotally supported by the supporting portion at the shaft portion, the link having a second fixing portion for fixing the wire harness; and

a harness protector provided on the supporting portion;

wherein the harness protector includes:

a harness guide portion for guiding to lead the wire harness to a harness guide path from the second fixing portion;

the harness guide path, successive to the harness guide portion, along which the wire harness is routed; and

a harness accommodating portion, successive to the harness guide path, for accommodating the wire harness bendably,

wherein the wire harness is led from the link to the harness protector to be routed in the harness protector, and

wherein an excess length of the wire harness is absorbed into the harness accommodating portion in conjunction with rotation of the link.

2. The harness routing structure according to claim 1 , wherein the wire harness is constantly curved to form a substantially loop-shaped bent portion in the harness accommodating portion so that a radius of the loop-shaped bent portion is expanded to absorb the excess length of the wire harness in conjunction with the rotation of the link.

3. The harness routing structure according to claim 2 , wherein a spring portion is provided in the harness accommodation portion to urge the loop-shaped bent portion in a direction of expanding the radius of the loop-shaped bent portion.

4. The harness routing structure according to claim 1 , wherein the harness guide portion has a first curved guide wall along which the wire harness is routed in a first direction before the rotation of the link, and a second curved guide wall along which the wire harness is routed in a second direction differed from the first direction after the rotation of the link.

5. The harness routing structure according to claim 1 , wherein the harness accommodating portion includes a peripheral wall and the wire harness is expanded toward the peripheral wall in conjunction with the rotation of the link.

6. The harness routing structure according to claim 4 , wherein the harness accommodating portion includes a peripheral wall and the wire harness is expanded toward the peripheral wall in conjunction with the rotation of the link.
