PROBLEM TO BE SOLVED: To provide a regenerating tube winding drum on which a regenerating tube can be spirally wound side by side and which suppresses a crease of the regenerating tube during winding, the regenerating tube being used for regenerating a pipe line and being deformed to have a crooked cross section. SOLUTION: The winding drum 1 is used for winding the regenerating tube thereon for transferring the tube which is used for regenerating the inner surface of the established pipe and is deformed beforehand to have the crooked cross section. The drum comprises a cylindrical body portion 11 on which the regenerating tube is wound and a pair of side plates 12 mounted on both the ends of the cylindrical body portion. An opening portion 13 is provided to insert the tube end portion of the regenerating tube into the cylindrical body portion. A tool is mounted in the cylindrical body portion to fix the tube end portion of the inserted regenerating tube, and a guiding structure is provided to prevent the wound regenerating tubes from overlapping each other.
