Abstract
A guide device includes a shaft member and a column. The column has a through hole formed therein and the shaft member penetrates the through hole of the column. A plurality of pockets are formed on an inner circumferential surface of the through hole of the column. The pockets are disposed on a plurality of cross sectional planes that are perpendicular to an axial direction of the column. In each pocket, there are provided an outer race or roller rolling axially on an outer circumferential surface of the shaft member, and a supporting shaft supporting the outer race rotatably. The column is formed of a plurality of splittable members that are divided on cross sectional planes each perpendicular to the axial direction of the column and that pass through a center line of the supporting shaft. The adjacent splittable members are centered by the supporting shaft.
