PROBLEM TO BE SOLVED: To provide a drum for winding a sheet-shaped member which can surely change over the range of a suction hole for sucking air by a simple structure and does not mark a useless contact trace in the sheet-shaped member. SOLUTION: A drum body 1 has a hollow part 13 extending in the axial direction, and the hollow part 13 communicates with each of the suction holes H1-H12. In the hollow part 13, a change-over member 20 formed along its inner peripheral surface is set attachably/detachably. An air passage (each second communication hole 20d, a first communication hole 20b, and a hole 20c) which makes each suction hole in a prescribed range in the axial direction of the drum body 1 and a suction device 30 communicate with each other is formed in the change-over member 20. When the change-over member 20 is replaced with another change-over member, the range of the suction hole for sucking air is changed over. Since the change-over member 20 is set in the hollow part 13, the change-over member 20 is prevented from protruding from each of the suction holes H1-H12 to the outside of the drum body 1.
