A sliding device for a storage case is provided which is durable and provides a smooth sliding motion even in environments, such as those encountered in a refrigerator, wherein the storage case is subjected to humid, cold (below the freezing point) conditions. The sliding device comprises a fixed rail fixedly mounted to an inner side surface of the storage case and having a roller coupling portion in which a first set of rollers are rollably received; a movable rail fixedly mounted to an outer side surface of the storage container and having a roller coupling portion in which a set of second rollers are rollably received; and a middle rail which is slidably mounted between the fixed rail and the movable rail so as to provide a coupling relationship therebetween which guides the rolling motion of the first and second rollers. The fixed rail, the movable rail and the middle rail, as well as the rollers, are made of an injection molded plastic.
