Summary:PROBLEM TO BE SOLVED: To facilitate increasing of kinds of feeding speed (spiral pitch) of a screw shaft, in a carrying device of a screw drive provided with fore-and-aft two driven rollers on a carrying traveling body side so as to transfer a screw shaft rod.SOLUTION: On a carrying traveling body 1 side, a first driven roller pair 8 having a narrow interval D1 between fore-and-aft two driven rollers 7a and 7b; and a second driven roller pair 10 having wide interval D2 between fore-and-aft driven rollers 9a and 9b are provided. On a traveling path side, a first screw shaft row 13 to which each driven roller of the first driven roller pair 8 is engaged, and a second screw shaft row 14 to which each driven roller of the second driven roller pair 10 is engaged, are provided. Screw interrupting space length L1 and L2 between both screw shaft rows 13 and 14 are same as the intervals D1 and D2 between the driven rollers of the driven roller pairs 8 and 10 engaged with the screw shaft rows 13 and 14 on an upstream side.
