摘要:
A steering shaft having an outer shaft and an inner shaft accommodated therein in a torque-locking, axially displaceable manner and an axial inner stop which projects radially outwards from an outer face of the inner shaft. When the inner shaft is pulled out of the outer shaft, the axial inner stop strikes against an axial outer stop projecting radially inwards from an inner face of the outer shaft, wherein the axial displacement of the inner shaft is limited in the pull-out direction. With regard to simple production of the outer stops with the least possible deformation of the entire cross section of the outer shaft, the outer stop is introduced by at least one forming process into an end portion of the outer shaft, wherein the axis of the direction of introduction in each case forms an angle of more than 20° with the radial direction of the outer shaft.
