Abstract
A miniature linear guide provides a guide rail having load ball rolling grooves, and a slider which is made up of a slider body having load ball rolling grooves which are confronted with those of the guide rail, a circulator having non-load ball circulating paths, and a holding plate interposed between the slider body and the circulator, and a number of balls rollingly fitted in the spaces defined by the load ball rolling grooves of the slider body and the guide rail and in the non-load ball circulating paths in the circulator. The miniature linear guide has a dust-proofing structure in which both end portions of the holding plate, as viewed in the direction of length thereof, are bent at right angles, thus forming protrusions, and seal members having sealing protrusions are formed on the protrusions so that the sealing protrusions are fitted in the load ball rolling grooves of the guide rail to sealingly close gaps formed between the guide rail and the slider.
