<p>A sliding guide apparatus guides a movable member for a base. A pair of guide surfaces (3) is formed on the base (2). A pair of sliding surfaces is formed on the movable member as so to be opposed to the pair of guide surfaces, respectively. Lubricating oil is supplied between the guide surface and the sliding surface. The sliding surface is configured so that one half portion (12A) of the sliding surface which is close to the center of gravity of the movable member is asymmetric with the other half portion (12B) of the sliding surface which is far from the center of gravity of the movable member. Since load of the movable member that acts disproportionately on the sliding surface is balanced with dynamic pressure of the lubricating oil that occurs between the guide surface and the sliding surface, it is prevented that the movable member is slanted.</p> |
