摘要： A winding device for a blind without pull cords is provided with a reel pivotal base and a cord-guiding base abutting against each other in the upper rail of a blind. A winding reel is axially assembled on the reel pivotal base, having its outer circumference formed with an oblique conical surface gradually shrinking from its first end to its second end to enable a linking cord to move forward automatically when the linking cord is wound on the winding reel. The cord-guiding base is provided with at least one push block at a location where the winding reel is pivotally rotated for guiding the linking cord to be wound side by side closely on the winding reel, preventing the linking cord from overlapping or wound irregularly after the linking cord is wound on the winding reel, enabling a blind to be collapsed or stretched smoothly.
