PURPOSE: A leveling apparatus is provided to move a movable body in a horizontal direction without a guide mechanism by restricting a rotary motion of a spindle support or horizontal movements of spindles. CONSTITUTION: A leveling apparatus comprises an upper support which is overlapped and stacked, an upper support(12), wedge-shaped movable body(16), and a lower support(14). Both sides of a spindle support(20) are fitted into concave portions(34) formed on both walls of recessed grooves of each support. A spindle(18) connected to a movable body with a screw joining is supported by the spindle support and free-rotated. |
