Abstract: A sliding device is disclosed for a drawer capable of reinforcing rigidity while reducing noise during operation by mixing and using a plurality of slide balls having different tensile strengths. The sliding device includes: a fixed rail fastened and fixed to a main body, a movable rail fastened and fixed to a storage body, and sliding on the fixed rail, an intermediate rail disposed between the fixed rail and the movable rail to guide the sliding movement of the movable rail, and ball assemblies disposed between the intermediate rail and the fixed rail and between the intermediate rail and the movable rail, respectively to move to be slidable, and provided with a plurality of slide balls having different tensile strengths, the slide ball having a large tensile strength being disposed at the outermost side thereof.
