<p>According to the present invention, a rectilinear guide device comprises: a track base (1) formed to provide a substantially U-shape in section and provided on the inner side surfaces thereof with rolling surfaces (12) for rolling elements (2); and a bearing block (B) having loaded rolling surfaces (31a - 31d) for clamping the rolling elements (2) in cooperation with the rolling surfaces (12) and for stroking in a recessed portion of the track base (1) in accordance with the rotating amount of a feed screw shaft (7) threadably coupled therewith; is characterized in that the bearing block (B) consists of a block body (3), rolling hole-forming plates (5) and lid members (4), and only the joining of the above-mentioned members can form a ball circulation course through which non-loaded balls circulate. Accordingly, a long bearing block can be easily produced, and the number of the loaded rolling elements are increased, so that a rectilinear guide device having a large maximum load and being compact in size can be obtained.</p> |
