PROBLEM TO BE SOLVED: To provide a screen door with a net storage frame, and a screen window, which enable a net to be easily detached with a winding device, as a framework of the screen door etc. is maintained without the detachment of the connecting blocks of the framework. SOLUTION: In both the connecting blocks, inner base plates made of a metal or a resin are fixed by screws with an interval in between via a fitting wall. In an interval section, an adjusting device is internally mounted at one end; a center shaft of the winding device is extractably connected to the adjusting device; a shaft receiving element, into which a lower end of the center shaft of the winding device can be extractably fitted, is held in a sandwiched state at the other end; and a guide groove, which slides the shaft receiving element from a place for supporting the shaft receiving element in a central part, until an opening is formed at a corner on this side, is formed at the inner base plate at the end so that the shaft receiving element can be pulled out to this side.
