The present invention relates to a roll blind comprising a rolling device provided at a lower end of a vertically suspending curtain sheet to roll the curtain sheet, and a shaft rolling and releasing a traction rod vertically extending from a head rail at an upper end to move up and down the rolling device at a lower end, the roll blind further comprising a driving gear rotating together with the shaft around a fixed shaft and having a cylindrical drum extending in an axial direction; a friction spring tightly wound around the drum and having a protruding end protruding in a radial direction; and a tube wheel rotating together with the friction wheel via the protruding end, wherein the curtain sheet comprises a front sheet and a rear sheet disposed front and rear with a predetermined horizontal interval therebetween, and a number of blind sheets connecting the front sheet and the rear sheet, the rear sheet is relatively fixed to the head rail at its upper end to be fixed in the horizontal direction, the front sheet has its upper end to move in a rotational direction according to a rotation of the tube wheel so that the horizontal and the vertical interval between the front sheet and the rear sheet can be adjusted simultaneously, and an inclination angle of the blind sheets is adjusted according to the adjustment of the horizontal and the vertical intervals between the front sheet and the rear sheet, so that light admission can be adjusted.
