The reason for installing the end of the light-shielding film 300 on the light-shielding film winding roll 510 and the light-shielding film fixing bar 400 as described above is that the light-shielding film 300 moves according to the rotation direction of the light-shielding film winding roll 510, When the end of the light-shielding film 300 is fixedly installed on the light-shielding film winding roll 510 and the light-shielding film fixing bar 400 in order to cover or open it, the light-shielding film 300 moves in a flat state and is stable without flapping. fixation is made

At this time, the guide means 410 is installed along the upper longitudinal direction of the ceiling frame 210 in order to be more stable and easily covered or removed when the light blocking film 300 is covered or removed from the ceiling.

On the other hand, the guide means 410 is, as shown in FIG. 2, on the upper part of the ceiling frame 210 in the longitudinal direction of the ceiling frame 210 to maintain an interval wider than the thickness of the light blocking film 300. The guide bar 411 and the lower guide bar 412 are installed, and between the ceiling frame 210 and the guide means 410, as shown in FIG. 3, the bracket 413 is fixedly installed.

Since the guide means 410 installed as described above moves along the upper/

lower guide bars

411 and 412 in a state where the light blocking film 300 is positioned between the upper/

lower guide bars

411 and 412, stable movement is made.

In addition, the guide means 410 includes the light-shielding film 300 when the light-shielding film 300 is covered or lifted from the ceiling, or when the covered state is maintained, the end of the light-shielding film 300 flaps due to wind or cannot be maintained flat. In order to prevent this, the guide A light blocking film fixing means 420 that moves while holding the end of the light blocking film 300 at regular intervals is installed in the means 410 .
