摘要： A tubular member (1) made of an elongated curling strip (1a) partly wound on a drum rotatable on the first axis, and partly curling around the second axis (H) into the tubular member (1). The first axis is perpendicular to the second axis (H). The tubular member (1) is extendable and retractable with rotation of the drum. The strip (1a) is provided with a number of protrusions (9) distributed on its surface along its length. The drive comprises a threaded element (3,7) rotatable around the second axis (H) and an abutment element (4,5) forming between each other a space adapted to accommodate a wall of the tubular member (1) in such a manner that the first side of the wall is in contact with the threaded element (3,7) and the second side of the wall is in contact with the abutment element (4,5).
