The fire prevention shutter for a curtain-type screen comprises: a main screen shaft which has an upper rail and a lower rail, and is formed a side surface thereof; a screen sheet rolled on the main screen shaft in a roll form; a towing bar connected to an end of the screen sheet and mounted on the screen sheet; a wire to which the towing bar is connected; a pulling screen shaft to wind the wire; and a drive transfer unit to which the main screen shaft and the pulling screen shaft are connected by a chain or a belt to rotate the main screen shaft and the pulling screen shaft when rotating to wind the wire. |
