The present invention relates to a tension control device of a roll screen which always tightly keeps a tensile condition of a screen by quickly and exactly controlling the tension of the screen by making a rotating member, which is coupled with a winding spring inside a winding pipe, and a controlling member, which is connected to the rotating member, operated in a gear operation way when the tension of the screen loosens as the elasticity of the winding spring is reduced or relaxed in a process of using the roll screen. The present invention maximizes user convenience by simply and easily controlling the tension of the screen with a simple tool such as a driver through a control portion, which is exposed to a front side of one fixing cap side of a case of the roll screen, while the roll screen is installed in a window frame when controlling the tension. |
