WINDOW SHADE AND ACTUATING SYSTEM THEREOF
An actuating system for a window shade includes a fixed support shaft, a rotary drum pivotally connected with the support shaft and rotatable for winding or unwinding a shading structure, and a limiting mechanism at least partially disposed inside the rotary drum and including a threaded portion provided on the support shaft, a stop portion and a limiting part respectively adjacent to a first and a second end of the threaded portion, and a follower engaged with the threaded portion, the follower being rotationally coupled to the rotary drum and slidable relative to the rotary drum. The rotary drum is rotatable in a first direction to drive the follower to slide toward a first position for engagement with the limiting part, and in a second direction to drive the follower to slide toward a second position for engagement with the stop portion.
