Abstract
In a window lock operating device comprising an L-shaped handle member having a short arm connected to rotatable lock operating shaft and a long arm serving as a grip, a tiltable lever is provided in said short arm and is urged by a spring toward a position in which one end of the lever engages a retaining notch in a bearing member to be firmly secured on the window. A push rod that is displaceable in the long arm of the handle member may be operated to tilt the lever out of engagement with the notch against the force of the spring.
