Abstract: The present invention discloses anon-power driven window capable of adjusting ventilation rate. When the sash is unlocked, due to combined action of the sash's gravitational torque and the expansion of a torsion spring against the sash, the window keeps open. The window is designed having a bigger size in the lower section below the pivot than that in the upper section. Subject to the outdoor wind blowing, the moment by the outdoor wind tends to shut the window. In addition, the upper screen is installed in the outer side of the pane above the pivot, while lower screen is installed to the inner side of the pane below the pivot. Thus the lower sash is exposed into the outdoor air and can be easily blown by the outdoor wind. Consequently, the stronger is the outdoor wind, the smaller is the effective opening of the window for ventilation, and vice versa.
