摘要： A winding mechanism for a window blind includes a base having two slideways, a rotation member rotatably mounted on the base and having an outer wall formed with a threaded guide portion, and a guide seat having an inner wall formed with a threaded guide hole screwed onto the threaded guide portion of the rotation member and an outer wall formed with two guide posts each provided with a roller slidably mounted in a respective slideway of the base. Thus, when the lift cord is wound around the rotation member, the guide seat is movable successively on the rotation member by guidance of the roller, so that the lift cord is wound around the rotation member serially and smoothly by guidance of the guide seat, thereby preventing the lift cord from being tangled.
