ABSTRACT:
A thin-walled rectilinear motion rolling guide unit comprising a bed member, a table member slidably movable relative to said bed member in the longitudinal direction, and a ball retainer interposed between said two members.
According to the present invention, a rack and pinion mechanism is provided between said table member and ball retainer, with the use of a different teeth-meshing ratio between the table member and the ball retainer such that the speed in rectilinear motion of the former is greater than that of the latter such as a value of 2:1 for example, so that by decreasing the relative velocity of the ball retainer with the table member, the displacement of the former with the latter in operation can be prevented under any stress applied vertically onto the unit, insuring a high precision operation with less sliding resistance.
