Abstract:
PROBLEM TO BE SOLVED: To provide a gas derivation member for an airtightness leakage test which ensures gas capturing efficiency while being pursuant to the JIS standard.
SOLUTION: The gas derivation member 31 comprises a gas outlet tube 33 of which a part starting from an exit end and ending at a part placed in a gas guiding liquid 1 is formed in a straight tube-like shape and a capturing device 35 which is connected to the exit end and has an outlet 53 which opens upward when the end face of the exit end is parallel to a liquid level 7. The gas derivation tube is formed in an L-shape so that end faces 39 and 41 are equally spaced apart from a curvature 37.
