The present invention relates to a roll screen arranged inside a window of a building to shield light on the window, and capable of preventing accidents occurred to babies or children due to a sagged pulling rope by preventing the sagging of the pulling rope from providing a rotational force to a winding roller. The roll screen comprises: a fixated frame; a winding rod installed in the fixated frame while having a rotary structure; a rotation deceleration part arranged on one end of the winding rod, converting a forward and a backward transfer force of a pulling rope to the rotational force, and then transferring the rotational force to the winding rod; a blind paper fixated on a top of the winding rod to control a shielding of the window through the forward and backward rotation of the winding rod; and a pulling rope adjustment unit. The pulling rope adjustment unit comprises: a lifting rail; a lifting roller installed in the lifting rail with a lifting structure on which the pulling rope is placed; a pulling spring receiving the pulling rope in the lifting rail by pulling the lifting roller on which the pulling rope is placed to the upper part of the lifting rail; and a stopper to fixate the lifting roller descended on the lifting rail by the pulling of the pulling rope on one spot of the lower part to deploy the pulling rope. |
