A guide device (1) includes a shaft member (2) and a column (3). The column (3) has a through hole (3a) formed therein and the shaft member (2) penetrates the through hole (3a). A plurality of pockets (4) are formed on an inner circumferential surface of the through hole (3a) of the column (3). The pockets (4) are disposed on a plurality of cross sectional planes that are perpendicular to an axial direction of the column (3). In each pocket (4), there are provided an outer race or roller (50) rolling axially on an outer circumferential surface (2a) of the shaft member (2), and a supporting shaft (6) supporting the outer race (50) rotatably. The column (3) is formed of a plurality of splittable members (31, 32, 33) that are divided on cross sectional planes each perpendicular to the axial direction of the column (3) and that pass through a center line of the supporting shaft (6). The adjacent splittable members are centered by the supporting shaft (6). <IMAGE> |
