A door includes an elongated bearing rail and at least one door section which is operatively connected to the rail for sliding movement in a direction along the elongation of the rail. The door section is so mounted relative to the rail as to perform transversal movement about an axis extending substantially in parallel to said rail. During the transversal movement of the door section frictional rotation between the bearing rail and the connecting means is precluded. |
