Accordingly, since the pinion gear 550 and the take-up gear 440 shown in FIG. 6 are formed in the moving shaft and the variable groove, respectively, it is possible to vary the pulling force even when the driving gear is pulled downwardly, The variable can easily be achieved.

7, the first curtain portion 200 or the second curtain portion 300 may be formed as a two-fold roll curtain combined with a transparent and a non-transparent portion, as shown in FIG. 7, And a second winding rod 320 is formed between the first driven gear 410 and the variable gear 520 or between the second driven gear 420 and the variable gear 520, And the second gear 700 is transmitted to the first and second driven gears 410 and 420 by a driving force generated through the variable gear.

That is, in the application of the double-layered roll curtain shown in FIG. 7, the second gear is used to match the characteristics of the curtain to be combined with the perspective and the non-perspective. However, And the first and second driven gears can be variously modified depending on the kind of the curtain, and can belong to the present invention.

4 and 5, when the variable gear 520 of the variable driving means 500 is engaged with the first curtain portion 300, the operation of the double-roll type curtain of the present invention according to the above- And are formed in a coupled state. Here, when the user wishes to wind up the second curtain 310 of the second curtain part 300, the user pulls the driving wire 600 downward, and the wire pulley 530 rotates accordingly.

The movable shaft 510 rotates in accordance with the rotation of the wire pulley 530 and the variable gear 520 positioned inside the variable housing 400 rotates together with the rotation of the movable shaft. Then, the variable gear 520 rotates, and the second driven gear 420, which is engaged with the gear, rotates. Since the second driven gear 420 is coupled with the second winding rod 320 on the same axis, the second winding rod 320 rotates in the same manner as the rotation of the second driven gear 420, 2 curtain paper 310 is wound and wound.

When the winding of the second curtain part 300 is completed, the user moves the driving wire 600 to the front side of the variable groove 430 by pulling the torsion spring 540 elastically deformed downward, (600). At this time, the moving shaft 510 moves forward from the rear side of the variable groove 430 and the moving shaft 510 is pushed from the front side of the variable groove 430 by the elastic force of the torsion spring 540, .

Then, the first driven gear 410 and the variable gear 520 are engaged with each other as the moving shaft 510 is pushed up toward the front side of the variable groove 430.
