Abstract
A steering shaft for a motor vehicle includes a hollow shaft and an inner shaft which is arranged coaxially in the hollow shaft. The inner shaft is configured to be telescoped relative to the hollow shaft in the direction of the longitudinal axis of the steering shaft and is connected in a torque-transmitting manner to the hollow shaft via at least one rolling body. The rolling body is received in a rolling body cage such that it can roll in the direction of the longitudinal axis between the inner shaft and the hollow shaft. In order to achieve a high operational reliability with a relatively low manufacturing complexity, the rolling body cage has at least one seal element which bears sealingly against the hollow shaft and/or the inner shaft.
