<p>Block members (9) are arranged on a keyboard (7) so as to oppose one another or substantially oppose one another with the upper part of an immersion nozzle (1) therebetween, and the slanted surfaces (13) of the block members are shifted in a prescribed immersion-nozzle-ejecting horizontal direction; thus, when an old immersion nozzle (1) is ejected in the prescribed horizontal direction by a new immersion nozzle (1') and is replaced, the ejection force required by an ejection device (12) is reduced.</p> |
