Automatic return device for doors, characterized by having a carriage integral with the upper and/or lower prolongation of the axis of rotation of the door leaf, which carries a set of two rollers arranged symmetrically and in a manner such that their respective axes of rotation being parallel to the said axis of the door leaf equidistant from the plane thereof, said two rollers being subject to the permanent pressing action of a plate pushed by a corresponding spring exerting its action substantially in the same direction as that of the theoretical closing line of the door, being able to save at will the relative angularity between the virtual plane passing through the axes of said rollers and the plane of the door leaf.
