PURPOSE:To prevent the chattering of a hinge part and secure the airtightness and adjust the pressing portion of an airtight member by fixing the shaft of the hinge in eccentricity onto a sleeve which is supported in turnable ways in a heating installed in a bearing installation part. CONSTITUTION:The shaft 9 of a hinge is inserted in eccentricity into a sleeve 8 which is inserted in turnable ways through a bearing 7a into the bearing fitting part 6 at the edge part on this side of an opened port side block 4, and fixed so as to revolve integrally with the sleeve 8. Further, the upper part of the shaft 9 projecting from the upper edge of the sleeve 8 is inserted into the shaft hole 13 of a door side block 11, and fixed by tightening the divided part by a tightening bolt. Since the shaft 9 is in eccentricity, the center shifts, accompanied with the opening and closing of the door 3, and the door 3 is shifted in nearly parallel to the opened port part side, and the pressing portion of an airtight member can be adjusted by freely varying the fixing angle alphabetween the shaft 9 and the door 3 by the divided part and the bolt. |
