ABSTRACT:
This ball spline is capable of omitting ball retaining claws on an outer cylinder, forming by grinding raceway grooves in an inner surface of the outer cylinder easily with a high precision, positioning and fixing retainers simply on the outer cylinder, and reducing the manufacturing cost. In this ball spline, each of the retainers is formed by a pair of ball retaining units, which are fastened to the outer cylinder by engaging outer projections formed on the ball retaining units with grooves formed in the outer cylinder. The locking bores in spacer rings are engaged with locking projections on the ball retaining units, whereby the spacer rings are fixed to the ball retaining units.
