Abstract
A telescopic shaft () has an inner shaft () and a tubular outer shaft () that are fitted to each other so as to be relatively movable in an axial direction (X) and to be able to transmit torque between each other. A row of a plurality of rolling bodies () is interposed between corresponding axial grooves () of the inner shaft () and the outer shaft (). A retaining member () moving together with the rolling bodies () while retaining the rolling bodies () has a facing portion () facing an end surface () of the inner shaft (). As the telescopic shaft () telescopes in and out, the facing portion () comes into contact with the end surface () of the inner shaft (), and this limits the movement of the rolling bodies () in the axial direction (X).
