Automatic closing device for doors essentially characterized in that it consists of a semicircular rail rail guide joined at its ends to the sides of the jamb surrounding the axis of the door and whose halves are inclined sloping and converging toward the center of such rail with which combines a roller mounted transverse the door so that it is housed in an opening made therein for the passage of the guide whose door is attached to a tubular shaft rotatable and hinged on hinges so that when the force ceases the manual that holds it open inwards or outwards descends by gravity by displacement of the tubular shaft on the hinges and by descent of the roller by the inclined halves of the guide in the middle part of which said roller is placed so that the door is closes and stays in this position.
