<p>The device (1) has a drive shaft (6) driven by a motor (4), and an output shaft (8) staying in effective connection with a window wing (2) i.e. movable window wing, which is positioned. A coupling unit (10) is connected with the drive shaft and the output shaft in a torque proof manner, and is arranged between the drive shaft and the output shaft, where a rotary motion of the drive shaft is coupled to the output shaft by the coupling unit. An angular position of the output shaft is adjustable with respect to the drive shaft.</p> |
