Abstract
A telescopic shaft includes an inner shaft, an outer shaft, a plurality of rolling bodies that are disposed between recessed grooves of the inner shaft and the outer shaft and form a line in an axial direction, a stopper, and a buffer body. The stopper restricts falling of the rolling bodies from the recessed groove of the inner shaft. The buffer body is interposed between the stopper and a rolling body at an end portion of the line. An end surface of the buffer body includes an inclined abutment portion that is inclined with respect to a plane perpendicular to an axis of the inner shaft. The abutment portion abuts against the rolling body at the end portion of the line at a stroke end of the inner shaft with respect to the outer shaft.
