  • the lower side between the unit member 10A and the unit member 10B is always closed by the lower wall main body portion 131 and the lower wall thin wall portion 132 of the lower wall 13 in the process of relative rotation.
  • the unit members 10A and the unit members 10B are closed at a high degree of closure even on both side surfaces because the right walls 11R and the left walls 11L are partially overlapped and connected so as to be relatively rotatable. . Therefore, since the cable chain 1 is closed at a high degree of closure on the upper side, the lower side, and both the left and right sides in the entire process of bending, a part of the cables 2 may come out of the internal space and be damaged. It can be deterred.
  • the lower wall thin wall portion 132 of the unit member 10A adjacent to the front side is along the connecting portion between the pair of side walls 11R and 11L of the rear unit member 10B and the lower wall main body portion 131 Is slidably held in a pair of sliding grooves 11R6 and 11L6 having an opening. For this reason, the lower thin wall portion 132 is restrained from being deformed in the out-of-plane direction in the entire process of bending, and the lower side can be stably closed.
  • the pair of claws 11R9 and 11L9 which the pair of side walls 11R and 11L have can slide the upper wall thin wall portion 122 of the adjacent unit member 10B from above when the upper wall main body portion 121 is in the closed state. Hold. For this reason, deformation of the upper wall thin wall portion 122 of the upper wall 12 in the out-of-plane direction is suppressed, and the upper side can be stably closed.
  • the unit member 10 is integrally formed of polypropylene resin having high flexibility, high flexibility of the upper wall thin wall portion 122 and the lower wall thin wall portion 132 is ensured.
  • the upper wall thin wall portion 122 smoothly slides between the upper wall main portion 121 and the claws 11R9 and the claws 11L9, and the lower wall thin wall portion 132 slides smoothly between the sliding groove 11R6 and the sliding groove 11L6. Since it bends easily, relative rotation between unit member 10A and unit member 10B becomes easy.
  • the cable chain 1 can be smoothly bent following the bending of the cables 2.
  • the unit member 10 is formed by the polypropylene resin.
  • the unit member 10 may be formed of a highly flexible material, and the material forming the unit member 10 may be, for example, polyethylene resin, polyamide resin, or elastomer.
  • the cylindrical protrusion 11R3 of the above-described embodiment is cylindrical with a rightward projection, but may be cylindrical, for example.
  • the upper thin wall portion 122 and the lower thin wall portion 132 are both formed to extend rearward, and the extending direction is the same. Not limited to this, the direction in which the upper wall thin wall portion 122 and the lower wall thin wall portion 132 extend may be opposite.
