Zusammenfassung:A motor vehicle steering shaft (3) is provided with: an inner shaft (11) and a tubular outer shaft (10) fitted into each other and to transmit a torque to and from each other; a rigid coupling element (25) for rigidly coupling the inner shaft (11) and the outer shaft (10) in a circumferential direction (C) of the inner shaft (11) when a relative rotation amount of the inner shaft (11) and the outer shaft (10) exceeds a predetermined range; and an elastic coupling element (36) for elastically coupling the inner shaft (11) and the outer shaft (10) in the circumferential direction (C) of the inner shaft (11) when the relative rotation amount of the inner shaft (11) and the outer shaft (10) is within the predetermined range. The elastic coupling element (36) includes a resin member (36). The inner shaft (11) and the outer shaft (10) are elastically supported mutually via the resin member (36) at a central position of the predetermined range when no torque is loaded to the steering shaft (3).
