Abstract

A steering shaft for a motor vehicle includes a hollow outer shaft with a longitudinal axis. An inner shaft is arranged coaxially within the outer shaft. The inner shaft telescopes longitudinally relative to the outer shaft and is connected in a torque-transmitting manner to the outer shaft via a rolling body. The rolling body can roll in the direction of the longitudinal axis and the rolling body bearing in a positively locking manner in the circumferential direction about the longitudinal axis between rolling body raceways on the inner and outer shaft. The steering shaft includes a securing element with a supporting body arranged between supporting faces configured on the inner shaft and on the outer shaft, which at least one supporting body can be supported in a positively locking manner in the circumferential direction. The supporting body is spaced apart in the circumferential direction from the supporting faces.
