<p>PURPOSE:To provide a cable connection structure which prevents the wear of a covering on a cable inserted into, and passed through, a flexible tube and which is constituted in such a way that a protective gas does not creep into the flexible tube. CONSTITUTION:In a cable connection structure, a multicore cable 22 into and through which a plurality of insulated core wires have been inserted and passed is inserted into, and passed through, an inside passage 18a at a flexible tube 18. In the flexible tube 18, a nut 24 is screwed to a male screw 26e at a joint 26 in a state that a holder fitted to an end part has been inserted into a recessed part 26d at the joint 26. The outer circumference of the multicore cable 22 is fitted to, and held by, a cable holding part 26b at the joint 26 so as not to be slid inside the joint 26 even when every movable part of an industrial robot 1 is operated, and it is possible to prevent a covering on the multicore cable 22 from being worn away or stripped off. A seal member 29 is inserted into a groove 26c at the joint 26.</p> |
