This invention relates to a curtain retractor without drawstring, which has a retractor major body comprising a mounting seat and a side cover. A transmission rod for coupling with a curtain retracting unit is provided within an accommodation space of the mounting seat. A worm is provided to mesh with a worm gear provided on the transmission rod. Further, the worm is connected with a rotatable rod unit which is to replace conventional drawstring. By implementing the non-drawstring type curtain retractor of the present invention, the accident of children's neck wrapping around by a drawstring, used in conventional curtain structure to roll up and down a fabric, to cause strangulation can be effectively avoided.
