Abstract
A guide tube (4) for the rotatable mounting of a steering spindle (2) of a motor vehicle is described, wherein the guide tube (4) is rolled cylindrically from a single sheet-metal section and is connected at an axial contact point (12), and wherein the guide tube (4) has elements (13-15) for the definably axially displaceable fastening in a bearing unit (1). The guide tube (4) is characterized in that the elements (13-15) are designed in the form of at least two beads (13) which are distributed over the circumference, run axially, are formed circumferentially on both sides by ribs (14, 15) expanding the cylinder circumference and are formed in the sheet-metal section. A production method for such a guide tube (4) is also described.
