Abstract: A sheet-like member holding device includes a first holding unit disposed between a gripper receiving portion and a side wall of a gap, and configured to hold a base of a non-metal sheet. The first holding unit includes a space in which the base is inserted while the non-metal sheet extends inward in a radial direction from an outer surface side of a printing cylinder, and an abutment wall configured to restrict movement of the base to the outside in the radial direction. An end portion of the space in an axial direction of the printing cylinder is open to the outside. This makes it possible to attach and detach the non-metal sheet by a simple method without moving a gripper member or gripper pad.
