<p>ÄSubjectÜ In a cable drag chain wherein a plurality of link members each comprising a pair of right and left side plates and connecting plates connecting upper and lower edges, respectively, of the side plates are connected together contiguously in a bendable manner, the connecting plates are to be connected strongly to the side plates. ÄSolutionÜ A cable drag chain 10 comprises a plurality of resinous link members 12 connected together contiguously in a bendable manner. Each link member 12 has a pair of right and left side plates 14, 16 and connecting plates 18, 20 which connect transversely upper and lower edges, respectively, of the side plates. A pair of connecting arms 22, 22 are projected at both ends of the connecting plate 18. A connecting arm receptacle portion 24 for receiving the connecting arms 22, 22 therein is formed in the upper edge of each side plate 14 (16) centrally in the longitudinal direction of the cable drag chain. Engaging pins 26 are projected from abutment surfaces of the connecting arms 22, 22, while engaging pin receptacle holes 28 are formed in abutment surfaces of the connecting arm receptacle portion 24. The engaging pin receptacle hole 28 is open sideways of the side plate 14 (16) , but is closed at the upper edge of the side plate 14 (16) , so that the connecting plate 18 is difficult to be disconnected above the side plates 14 and 16. <IMAGE> <IMAGE></p> |
