摘要: In a furnace for heating an optical fiber preform to be inserted from insertion opening, the includes annular sealing body clearance gap between and opening. The is formed stacked disks respectively having hole in its center area. disk has slits inner edge of toward periphery side flexible portions that are defined by bend interference with into hole. When body, bend.
