Therefore, the second curtain fabric 22 is relatively separated from the first curtain fabric 21, and the transverse sheets 23 are pulled apart to be horizontal. Thereby, the light can pass through the first curtain fabric 21 and the second curtain fabric 22 without being blocked by the transverse sheets 23 , that is, the curtain fabric unit 2 can be made light-transmissive. If the perforations 24 are positioned as shown in Figure 7, the ends of the levers 32 can be pressed against the connection point close to the second curtain fabric 22 and the transverse piece 23 located above the levers 32, thereby providing optimal support. Effect.

In other words, when the curtain unit 2 has not reached the fully lowered position, the user can use the lever 32 of the curtain opening unit 3 to push against the second curtain 22 to pull the transverse panels 23 horizontally.
