Abstract: An auxiliary operating device for manually operating a normally motor-operated closure between open and closed positions, the device comprising a shaft, a driving member mounted to the shaft and displaceable between an idle position and an operational position wherein the driving member is operatively coupled to the closure. The device further comprises a manual actuator for first displacing the driving member from its idle position to its operational position and then driving the driving member in order to displace the closure. The actuator can be advantageously mounted at either end portions of the shaft irrespectively of the position of the driving member on the shaft.
