Zusammenfassung:	PURPOSE:To prevent the dust frmation in a vacuum container by introducing leaked gas little by little into the vacuum container at the initial stage of leak of the vacuum container. CONSTITUTION:When a valve 28 is opened, the leaked gas branched from a leaked-gas introducing line 26 into a branched line 27 is introduced into a space B. The leaked gas is introduced little by little into a vacuum container 10 from the space B through a gas introducing slit 31. When the force due to the pressure difference between the spaces A and B reduces than the force of a coil spring 30, an orifice 23 is opened gradually. The amount of the leaked gas introduced into the vacuum container 10 from the space B increases because of the increase of the area of the opening.
