<p>PROBLEM TO BE SOLVED: To firmly mount a coupling plate on a side plate, in a cable drag chains a plurality of link bodies having a pair of right and left side plates the upper and lower edges of which are intercoupled through a coupling plate are bendably arranged in a connected state. SOLUTION: A cable drag chain has a structure wherein a plurality of link bodies made of resin bendably are arranged in a connected state, each link body comprises a pair of right and left side plates 14; and a coupling plate 18 spans between the upper and lower edges of a side plate. A pair of coupling arms 22 and 22 are protruded from the two ends of the coupling plate 18. A coupling arm containing part to contain the coupling arms 22 and 22 are arranged in a recessed state in the central part in the longitudinal direction of the cable drag chain of the upper edge thereof. The coupling arms 22 and 22 have a contact surface from which an engaging pin is protruded and meanwhile, the containing part has an engaging pin containing hole formed in a recessed state in a contact surface. The engaging pin hole is opened to the side of the side plate 14 but closed at the upper edge of the side plate 14, and the coupling plate 18 is hardly separated to a position above the side plate 14.</p> |
