PROBLEM TO BE SOLVED: To provide the processing method for the cable excessive-length part which prevents a cable from buckling in case of an earthquake, etc., and secure sufficient excessive length even in a relatively narrow place. SOLUTION: The excessive-length part 4 of the cable is formed in the end- part side space 3 of a conduit 2 wherein the cable 1 is laid and this cable excessive-length part 4 is processed. In this case, the cable excessive-length part 4 is wound to a specific diameter to form a winding part 6, which is held in one body with a holding material which breaks with the tensile force when the cable 1 is drawn toward the conduit 2 without curving the cable 1 to less than its permissible minimum radius of curvature. |
