A rolling door having a door leaf and guides arranged on both sides, each of which includes a vertical portion and a spiral portion, wherein the door leaf is received in the spiral portions in the form of non-contacting winding layers when the rolling door is in the opened condition. A drive mechanism for operating the rolling door has a motor, a drive shaft and drive organs. The drive organs are arranged on both sides of the door leaf and the drive shaft establishes a driving connection between the drive organs. In one embodiment, the drive shaft is arranged in the central area of the spiral portions of the guides of both sides and extends from one side of the door to the other. Hereby a rolling door is obtained whose structural height in the area of the door lintel is reduced while maintaining a small installation depth.
