Abstract
End rings fit over the opposite ends of the retainer inserted in the outer sleeve to keep properly the retainer against either of rotational and axial directions. End rings fit over the opposite ends of the retainer extending out of the outer sleeve to make abutment against the outer sleeve to cover the outside peripheries of the retainer. The circular groove of the retainer is composed of the raceway groove having the raceway surface with the slit, the return passage lying in parallel with the raceway groove and a pair of turnaround passages to intercommunicate between the raceway groove and the return passage. The end rings are kept in angular location against rotation by means of engagement between the first projections at the opposite ends of outer circular groove of the retainer and the second projections in the inside circular grooves of the end rings. The outer sleeve is to keep the retainer in lengthwise direction.
