[Scope of utility model registration request] A rotating drum for winding a winding curtain is installed in the long part of each of the convex housing having a horizontally elongated vertical cross section and the reverse convex housing having protrusions facing each other at both ends, and in the convex housing, A continuous slit is bored across the top surface of the protrusion and the end face and bottom face of the long part, while in the case of a reverse convex type casing, a continuous slit is bored across the bottom face of the protrusion and the end face and bottom face of the short part, corresponding to the slit. A convex curtain device and a reverse convex curtain device each having continuous slits can be used so that each adjacent rolled up curtain passes through these slits and hangs down with their sides overlapping each other. A connected roll-up curtain device characterized in that the protruding portions are overlapped vertically, and a convex casing and a reverse convex casing are connected in sequence so as to be combined.
