PURPOSE:To reduce running resistance of a rolling roller, by positioning rollers, whose maximum number of pieces is close to (an integer +0.5) pieces, within a semicircular arc state directional conversion path connecting between both ends of a linear path of the inside of an endless circulating path. CONSTITUTION:The titled device is so formed that the maximum number of pieces of rollers becomes close to (an integer +0.5) pieces, under a conventional case wherein gammanot equal to 0 is given when the angle gamma is formed with a shaft center of a return path 4 and a shaft center of a load track 3 in relation to a horizontal plane passing through a shaft center of the load track 3 consisting of right angle V-shaped grooves 11, 12 to be formed respectively on the side 9 of a track rail 6 and the inner side 10 of a casing 7 confronting with the side 9, i.e., a bisecting plane (h). With this construction, it becomes possible to contrive a reduction of stick slip of the roller 1. In this instance, as for the roller 1, a roller whose diameter and length are about identical with each other by a used. |
