ABSTRACT:
This ball spline has a structure in which the raceway grooves can be made in a slider with ease and with a high accuracy by employing a raceway groove forming technique used in a linear rolling bearing. A casing in the slider has an opening extending over the full longitudinal length thereof and used for saddling the casing on a ball spline shaft. The outer surface of the casing is provided with a working reference plane which is used when the raceway grooves are formed in the inner surface of the opening. The casing can be fitted in a circular bore of a housing, and has arcuate surface portions on its outer surface which can support the inner circumferential surface of the circular bore of the housing. The axis of the ball spline shaft is offset from that of the circular bore of the housing.
