Abstract
A cable drag chain includes a plurality of ring-like inner links pined together at front and rear ends thereof. Each of the inner links has opposite end faces serving as stopper surfaces engageable with the stopper surfaces of the adjacent inner links to limit the angle of pivotal movement between the adjacent inner links. A ring-like outer link is detachably mounted to a joint portion between two adjacent inner links and surround the joint portion so as to close a space formed between the two adjacent inner links.
