Abstract
A steering shaft for a motor vehicle has an inner shaft, arranged in an outer shaft that is displaceable axially in the direction of an axis of rotation. The inner shaft includes axially running radial projections on its outer side. The outer shaft includes axially running grooves on its inner side, into which grooves the projections of the inner shaft engage in a positively locking manner in a direction of rotation and displaceably in an axial direction. With regard to fault-free operation during fluctuating temperatures, on the inner shaft, there is arranged a profiled sleeve with undulating cross-sectional profile, the inner surface of which lies against the flanks of the projections of the inner shaft and the outer surfaces of which lie against the flanks of the grooves of the outer shaft, wherein the profiled sleeve is connected to the inner shaft at one or more fastening points.
