ABSTRACT:
A roller type linear movement guiding device comprises: a plurality of roller type linear movement guiding bearings each having a number of rollers which circulate infinitely while rolling on a flat track surface; a holding board holding the bearings on the flat track surface; a table fixing board mounted over the holding board; and a steel ball inserted in recesses formed in the opposed surfaces of the holding board and the table fixing board at the load centers, so that the table fixing board is poised statically through the steel ball. With the device, even when the table fixing board is inclined, the holding board is held poised statically, whereby the roller type linear movement guiding bearings will never be twisted.
