A device for supporting and moving curtains, comprising a support element (1; 27; 38; 49; 90) of the curtain, with rolling elements (2) which are apt to contact, in a rolling manner, the upper external surface of rods (50), which are devoid of longitudinal slide rails. The rolling means form a roller or wheel having a circular groove or a central channel, which conforms to the circular section of the cable or rod. In a different embodiment, the rolling means (2) are rollers having preferably a cambered section (convex section), and are integrated in an annular structure. The rolling means (2), if made of metal, may be laser worked in order to obtain perfectly smooth surfaces.
