Abstract

PURPOSE:To reduce a whole outer size, by a method wherein a nut is formed in a half-split type shape, and a connection line to interconnect passages is situated on each of end surfaces on both sides with a central recessed part, adapted to dispose a screw shaft, therebetween. CONSTITUTION:By forming a nut 2 in a halt-split type shape, passages 5 divided by the nut are interconnected on the end surfaces on both sides of the half split-type nut 2 through connection passages 9 with a central recessed part, adapted to dispose a screw shaft 1, therebetween. Thereby, a passage to circulate 8 nut and a ball is not protruded toward the one side (for example, the upper or the lower side) in the radial direction of the screw shaft 1, and thus a whole outer size is compacted by an amount by which the nut and the passage are eliminated. The parted passages 5 are interconnected through a connection line 6 to form a circulating passage 7, and thereby during relative rotation, a ball located between the nut 2 and the screw shaft 1 is circulated through the circulating passage 7 like a conventional ball and screw.
