PURPOSE: A driven bracket of a roll screen is provided to extend a life of a roll driving unit and an operating chain by friction of a driven bracket and a shaft unit and to simplify coupling work by guiding a shaft pin to couple a take-up roll. CONSTITUTION: In a roll screen composed of a take-up roll installed to take up or down a screen, a roll driving unit installed to one side of the take-up roll to make a user operate the take-up roll, an operating chain operating the roll driving unit using rotary force, a driving bracket supporting one side of the take-up roll with the roll driving unit, a driven bracket(260) supporting the other side of the take-up roll without the roll driving unit, and a fixing bar binding up the upper ends of the driving bracket and the driven bracket(260) mutually, then fixing to a wall, the driven bracket(260) of a roll screen contains a tubular reinforcement support unit(11) projected to improve the bearing strength of a shaft groove(261) of the driven bracket(260), one or more guide incline unit(12) formed axially on the reinforcement support unit(11) to guide a shaft pin to the shaft groove(261) of the projected reinforcement support unit(11), and a coupling guide wall(13) preventing the lateral separation of the shaft pin coupled to both sides of the guide incline unit(12), then guiding to the shaft groove(261). |
