A cordless window curtain includes a curtain connected between the head box and the bottom bar. A controller, a fixed unit and a movably unit are located in the head box. The movable unit is movably located between the controller and the fixed unit. Multiple driving ropes go around guide members of the movable unit and the fixed unit. The resilient rope goes over the pulley in the controller and two ends of the resilient rope are respectively connected to the controller and the fixed unit. By lifting or lowering the bottom bar, the resilient rope is activated to move the movable unit so as to pull or release the driving ropes to allow the curtain to be lifted or lowered. |
