PURPOSE: An apparatus for sealing the muffle coupling part of a bright annealing furnace is provided in which sealing is done in proper form even in case of deformation of the sealing apparatus, deformation acceleration thereof is prevented by early correcting the deformed part, and the deformation of the sealing part is immediately sensed. CONSTITUTION: The apparatus comprises a sealing part for maintaining air-tightness inside a heating stand, wherein the sealing part consists of a case (10) on the upper part of which a flange is formed so as to be bolt linked to the upper part of a heating stand (100), and on the inner side of the lower surface of which a ring shaped support is formed, vertical pins (11) vertically installed and arranged along the flange with spaced apart from each other in a certain distance, a ring shaped ceramic wool (12) lain on the support at the inside of the case, an intermediate case (13) which is inserted into the ceramic wool (12), and on the flange formed on the upper part of which holes (14) are formed so that the vertical pins are inserted into the holes, a ring shaped intermediate ceramic wool (15) which is lain on the support of the intermediate case so as to maintain air-tightness with a muffle (140), and a cover (16) on the surface of which holes (17) are formed so that the vertical pins are inserted into the holes, thereby covering and pressing the intermediate ceramic wool; and a pressing part for maintaining air-tightness condition by pressing the cover, wherein the pressing part comprises a plurality of fixing plates, a rotation bar, a pressing plate, a driving cylinder, a link member, and a subsidiary link member.
