PROBLEM TO BE SOLVED: To provide a winding drum of a sheetlike member which certainly enables the changeover of the range of a suction hole for sucking air by a simple structure and forms no useless contact mark to the sheetlike member. SOLUTION: A suction hole changeover member 14, which allows a hollow part 13, a plurality of suction holes 12 and respective suction holes 13a to communicate with each other and allows a predetermined range of the suction holes 12 and the respective suction holes 13a in an axial direction to communicate with each other and allows the other suction holes 12 and the respective suction holes 13a not to communicate with each other, is inserted in the hollow part 13 in a freely detachable manner. Accordingly, air can be sucked from the suction holes 12 of the predetermined range in the axial direction among the suction holes 12. Further, by replacing the suction hole changeover member 14, the range of the suction holes 12 for sucking air can be changed over, that is, the range of the suction holes 12 for sucking air can be certainly changed over by a simple structure.
