PROBLEM TO BE SOLVED: To provide a structure of winding a cable into layers capable of surely avoiding the looseness of the winding. SOLUTION: Cables are wound by two or more layers on a winding drum 3, and an interlaid film 4a having a width D wider than the width H of the winding drum 3 is provided in at least one or between more layers of the cables. In both side ends of the wide interlayer film 4 are rising parts 6 rising along flanges 5 in both side ends of the winding drum 3, and notches 8 are formed in the rising parts 6. The notching direction of each of the notches 8 makes a sharp angle α with respect to the rotational direction of the winding drum 3 when the cable is wound. Thus, the cables are sequentially brought into point- contact with the notch-forming parts from the deep sides of the notches 8 to end edges, shocks generated by the point-contacts are suppressed to be very small to prevent the fallings of the rising parts 6, and the looseness of the winding caused by the fallings of the rising parts 6 is prevented. |
