Driving device for guillotine windows, characterized in that it consists of two parallel crossbeams linked together by two bars articulatedly, with the upper crosspiece being the glass holder and the lower one being fixed on the floor, both bars being requested by coil springs that are fixed on them by means of hooks located in such a way that the lever arm is variable as a function of the proposal and tension of the springs, whereby the compensating effect of the weight of the glass is kept constant which is eventually improved by means of friction dampers placed in the joints.
