Abstract
A window curtain driving assembly is revealed. A pulley driving assembly is pivotally connected to a main body. Pulleys disposed on the pulley driving assembly slid in a curtain track. Thereby the window curtain driving assembly rotates along curves of the window track so that it can also be applied to the curved window track. An auxiliary pulley set is mounted and fixed on a top of the main body. The pulley mount is oriented toward a given direction by the second latch bar on one side of the pulley driving assembly being mounted in the auxiliary pulley set. Thus the window curtain driving assembly can also be applied to a straight curtain track for extension or retraction of a curtain.
