A fan (2) is disposed in the treating-chamber (1), and a fan-driving shaft (13) of the fan (2) is introduced to out of the wall surface from the wall surface of the treating chamber (1) and linked with a driving device (3). A bearing (21) pivotally supporting this fan-driving shaft (13) so as to be relatively rotatable, is fitted to the wall of the treating-chamber (1) through an interposing member (23), and inert gas passages (25) (26) for spouting the inert gas are formed in the interposing member (23) at inserting gap with the fan-driving shaft (13) generated in the interposing member (23).
