Abstract: A cord divider is positioned on both sides of the cord winder of the control box of a cordless window curtain. Each cord divider is equipped with protrusions and crosspieces. When the cords are pulled out from the cord divider, the cords do not tangle or knot. The cords are wound up on the driving gear set, and the driving cord device prevents the cords from overlapping and causing uneven heights on both sides of the curtain. The use of cylinders in the cord dividers prevents excessive friction of the cords during use. There is no need to change the current cooperation way between the cords and the cord winder.
