ABSTRACT A driving device (1) for substantially linear movement of a driver (29) included in the device comprises a shaftless spiral (10) rotatable around its longitudinal axis. The spiral encloses at least one sliding body (30) which is provided with at least one element (31) projecting from the sliding body which passes between two spiral turns (16a,16b) of tile spiral located adjoining one another. The sliding body co-operates by means of elements (31) with an element (60) secured against rotational movement corresponding to the rotation of the spiral which prevents the sliding body during rotation of the spiral from rotating synchronously with the same. An elongated element (22) oriented in the axial direction of the spiral (10) is connected at its one end to the sliding body (30) and at its other end to the element (60) to form the driver (29). On rotation of the spiral the sliding body (30) and consequently also the driver (29), are moved in the axial direction of the spiral for moving of the element (60).
