A winding device for a blind includes two pivot seats, two limiting members respectively pivoted to the pivot seats, a spring member having first and second end portions respectively connected to the limiting members, an outer tube sleeved on the spring member, and two tubular sleeves connected between one of the limiting members and the outer tube. When the tubular sleeves are driven to rotate by a blind body of the blind, one of the tubular sleeves drives one limiting member to rotate synchronously, but the other tubular sleeve cannot drive the other limiting member to rotate therealong, such that the first and second end portions of the spring member are twisted to provide a resilient restoring force for balancing and positioning the blind body.
