PURPOSE:To provide a cryogenic container capable of preventing sufficiently also a light thermal oscillation which is generated in pipings. CONSTITUTION:In a magnetic container, which is provided with an internal container 2 with a refrigerant liquid put therein, a vacuum tank 3 housing this container 2 heat-insulated in a vacuum to the outside, a plurality of pipings 4a and 4b which are made to penetrate from the container 2 to the tank 3 and are led out to the outside, and an air chamber for preventing a thermal oscillation which is generated in the pipings, the air chamber 5 is partitioned into a plurality of chamber 5a and 5b by an elastic film 7. |
