A leakage testing apparatus for testing whether or not a hollow member of a hollow shape has a leakage, comprising: a hold mechanism for holding the hollow member such that the inside and the outside are isolated gas-tight from each other; an injection mechanism for injecting a testing gas into the hollow member held by the hold mechanism; and a leakage detector for sucking the gas around the hollow member held by the hold mechanism, to detect the leakage on the basis of the concentration of the testing gas in the sucked gas.

Appareillage d'essai d'étanchéité pour vérifier l'étanchéité d'un corps creux comportant : un mécanisme de retenue pour retenir le corps creux de manière à ce que l'intérieur et l'extérieur du corps creux soient isolés et étanches au gaz l'un par rapport à l'autre; un mécanisme d'injection pour injecter le gaz d'essai dans le corps creux immobilisé par le dispositif de retenue; un détecteur de fuite pour aspirer le gaz autour du corps creux immobilisé par le dispositif de retenue et détecter les fuites sur la base de la concentration du gaz d'essai dans le gaz aspiré.
