<p>PROBLEM TO BE SOLVED: To provide an apparatus for inserting an auxiliary wire that offers proper workability as compared with conventional apparatuses. SOLUTION: The auxiliary wire 10 for pulling a cable has prescribed tensile drag and ease of deformation, and is provided with air resistance function with which the wire is energized in an air flow in the direction of the air flow. A suction apparatus 7 is designed so as to suck the air in a conduit 4 for housing cables from one end of the conduit 4, to produce an air flow in the conduit 4 and energize the auxiliary wire 10 for pulling a cable, inserted into the conduit 4 from the other end of the conduit 4, by the air flow to move the auxiliary wire toward the one end of the conduit 4. Efficiency of operation of inserting cables into a conduit 4 is enhanced by the auxiliary wire 10 for pulling a cable and the sucking apparatus 7.</p> |
