Abstract

PURPOSE: To constitute a ball-circulating path free of discontinuous point by carving a circulation path on the cut surface of the patch which is divided into two pieces at the position agreeing with the center line of both return holes, and fixing these two divided patches joined together, onto a nut.
CONSTITUTION: The cut piece of a nut 4 is used as patch 4', and this patch 4' is divided into two parts (a) and (b) at the position agreeing with the center line of return holes 6 and 6, and on each surface of the divided pieces, semicircular groove is carved symmetrically so as to constitute tunnel-shaped circulation path, and the curved part 7' which constitutes longitudinal hole from the inlet which coincides with return holes 6 and 6 is constituted in arbitrary R-shape having small resistance, exceedingly suited for the shift of balls 5. As for the patch 4' consisting of two divided pieces (a) and (b), each semicircular groove is joined together, and both openings are accorded with the return holes 6 and 6, and then divided pieces are fastened by a fixing screw 8, and thus tunnel-shaped ball circulation path is constituted.
