ABSTRACT:
In a rectilinear guide apparatus wherein a female guide is disposed outside a male guide and four rows, for example, of rollers are interposed between the two guides and the male guide is rectilinearly movable relative to the female guide, rollers in two of the four rows are oriented in the same direction and all rollers in the other two rows are inclined so as to be substantially orthogonal to the rotation center axes of the rollers in the first-mentioned two rows. This rectilinear guide apparatus provides an effect similar to a combination of two rows of cross rollers, but provides higher strength and simplifies working of the rolling surfaces of the rollers.
