PROBLEM TO BE SOLVED: To prevent the fracture of a cable to improve a service life of the cable.SOLUTION: A cable assembly 4 is fixed at a second link 2 by a fixing member 3a, and fixed at a first link 1 by a fixing member 3b. The cable assembly 4 is provided with: a cable 41; and a rigidity adjustment member 42 for adjusting the rigidity of the cable 41. The rigidity adjustment member 42 is, for example, a sheet member wound around the cable 41. The rigidity adjustment member 42 is formed so that the bending rigidity of the cable assembly 4 continuously varies along an axial direction X. In addition, the rigidity adjustment member 42 increases rigidity more in a bending force concentrated part 51 adjacent to a joint 9 of the first link 1 and the second link 2 and bending force concentrated part 52 and 53 adjacent to the fixing members 3a and 3b than in bending force non-concentrated parts 54 and 55 other than the bending force concentrated parts. |
