ABSTRACT:
In this ball spline, ball retaining claws need not be provided on an outer cylinder body, and a retainer can be positioned accurately in the axial and circumferential directions of the outer cylinder body. The retainer is provided with axial movement stopper portions and turning preventing portions. In order to assemble the ball spline, the retainer inserted in the outer cylinder body is turned until the axial movement stopper portions slidingly contact both of axial end surfaces of the outer cylinder body with the turning preventing portions contacting turning preventing surfaces of the outer cylinder body. Consequently, the positioning of the retainer in the axial and circumferential directions thereof with respect to the outer cylinder body is effected. When the projections of the side rings are then fitted in the hollow spaces formed between the outer side surfaces of the projections and the wall surfaces of the grooves in the outer cylinder body, the retainer is fixed with respect to the outer cylinder body.
