摘要： PROBLEM TO BE SOLVED: To realize a gas leakage test when providing a metal seal in a lid of a cask.
SOLUTION: This leakage test device 200 performs the test by applying a load onto a central block 201 by a cylinder 220. The block 201 moves downward by the load application, so that an airtight state by a metal gasket 204 changes. Helium gas is supplied into a minute gap 208 from a gas cylinder 211, and its leakage amount is changed by the change of the airtight state of the metal gasket 204. The leaked helium gas is leaked into a gap 209 between the metal gasket 204 and an O-ring 206, and is detected by a gas detection device 213 through a passage 212 communicating with the gap 209.
