A harness protector structure for a link is provided, by which the durability of a bent part of a wiring harness is improved and interference with the outside is prevented when the wiring harness is rotated and bent by using a link. The harness protector structure includes: a support part; a link rotatably connected to the support part; a protector provided on the link; and a bulging part having a wide opening opened at one end-side of a body part of the protector, wherein a wiring harness is arranged from the support part into the protector, wherein when the link is rotated, a following part of the wiring harness, which follows a bent part of the wiring harness, passes through the bulging part from the opening, and the wiring harness is guided to the outside from the body part while a slack of the wiring harness is absorbed.
