CONSTITUTION: A cable chain comprises a plurality of side bands(10), a roller assembly(20), and a skid(30,40). The side bands are connected sequentially. The roller assembly is rotatably supported in the side band in a state where the bottom of the roller assembly is protruded from the bottom of the side band. The skid is supported in the side band and has a vertical motion of a specific length. The skid is elastically supported upward by the elastic unit. If the skid moves downward by an external force, the bottom surface of the skid is placed under the bottom of the roller assembly. The skid comprises a plurality of latch protrusions(34a) on one side thereof.
