PROBLEM TO BE SOLVED: To realize the smooth driving of the disk wire by dissolving the troubles caused by allowing the joint to bite with the carrying gears in the disk wire joint structure for feeding pipeline, further simplify the installation of the joint and lower the production cost. SOLUTION: The joint 20 is made in a tubular shaft shape having the tapered parts 20a on the internal circumferences at both ends. The disk wire 13 is inserted into the shaft hole 22 of the joint at the one end 13a of the wire to be connected and the joint is fixed to the one end of the wire with the screw to prepare the joint part A between the carrying disks 16 (16A-16A) whereby the carrying disk is omitted to make the distance D between the carrying disks double of the prescribed fitting pitch to form the non-biting area in which the carrying disk does not bite with the carrying gear in the corner part in the feed-carrying pipe.
