Abstract
PURPOSE: To increase the shield effect, by making approximately equal the diameter of one shield body among a plurality of external air shielding bodies to the inner diameter of the core tube, in providing a plural number of exteranl air shielding bodies with the rod used for the boat mounting semiconductor wafers to put it in or out of the core tube.
