To solve a problem on various kinds of bad influences caused by the attachment of a vapor of fats and oils generated from a treated matter, onto an upper face of a supporting base, in a case where the supporting base conveyed with the treated matter by a conveying roller is also used as a door for opening and closing an inlet and outlet port of a lower wall of a heating chamber.
In a vacuum sintering furnace 10 wherein the conveying roller 38 is mounted at a lower part of the heating chamber 14, the treated matter W is conveyed to a part just under the heating chamber 14 with the supporting base 40, and then the treated matter W is lifted up into the heating chamber 14 to be heated, a small cradle 42 for receiving the treated matter W is inserted between the supporting base 40 and the treated matter W independently from the supporting base 40, a through insertion opening 44 is formed on a position just under the cradle 42 of the supporting base 40, so that the treated matter W on the cradle 42 is separated from the supporting base 40 and lifted up by an elevation rod 38 through the insertion opening 44, and is inserted into the heating chamber 14.
