A pulling cord winding apparatus for window shades is installed on a bottom rail of a window shade includes a upper cap and a lower seat, two elastic take-up reels, two elastic coils held in the elastic take-up reels having two ends latched thereon, an elastic reed bridged a post located on one side of the center housing compartment and each of two brake elements; and a push rod located between two brake elements to form a forced contact. The push rod is depressible forwards and retractable rearwards to retract and press the brake elements to allow a coarse surface formed on an outer side of the brake elements to be spaced from or compressed on the two elastic take-up reels to form a braking or rotating condition and allow the two elastic coils to be retracted or extended to extend or retract the window shade to a selected location.
