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