An elevating container includes an elliptically shaped main tube, a non-circularly shaped moveable support unit which moves upwardly or downwardly along an inner surface of a storage tube of the main tube without rotating, and a driving unit fitted to the main tube to rotate in threaded engagement to the support unit without moving upwardly or downwardly. A seal section at the lower end of the inner peripheral surface of the storage tube and a sealing cylinder at the lower end of the support unit are air-tightly fitted to each other. In addition, positioning ribs are provided at the lower end of the storage tube, and positioning notches are provided at the lower end of the moveable support unit. When the positioning ribs and the positioning notches are engaged with each other, a circumferential misalignment between the main tube and the support unit is corrected.
