The upper end of the stretchable shutter 610 is brought into contact with the upper stopper 350 and the upper end of the stretchable shutter 610 is moved upward The retractable shutter 610 is folded by the further elevation of the lifting member 340. [ At this time, the door unit 600 is fully opened.

The lower stopper 360 is a member that guides the stretchable shutter 610 to unfold while preventing the further downward movement of the stretchable shutter 610 when the stretchable shutter 610 is lowered as shown in FIG. The lower stopper 360 may be installed to be in contact with the column or the cover 120 and with the elevating member coupled to the retractable shutter 610. Therefore, when the elevation member 340 is lowered in the folded state of the retractable shutter 610, the retractable shutter 610 gradually expands and descends. When the elevation member 340 contacts the lower stopper 360, The fall of the shutter 610 is blocked. At this time, the door portion 600 is completely closed.

In the third embodiment constructed as described above, the length of the screw may be shorter than the screw length of the second embodiment.

In the embodiment of the present invention, the door 600 is opened when the retractable shutter 610 is moved upward, and the closing is performed when the retractable shutter 610 is moved downward. In contrast, The door portion 600 may be closed when the extendable shutter 610 moves upward and the door portion 600 may be opened when the extendable shutter 610 moves downward.

In addition, for example, the ropes 630 may be provided by connecting a pair of stretchable shutters 610 provided on the both side struts 100. [ As another example, only one stretchable shutter 610 is provided on one strut 100, tensioning means is provided on the other strut 100, and the stretchable shutter 610 is connected to tensile means (not shown) 630 may be installed.
