母材の製造装置。[Scope of Claim for Utility Model Registration] (1) A heating furnace for dehydrating and sintering the porous base material of an optical fiber to make it transparent, a furnace tube that penetrates the inside of the heating furnace, and a rotating device inside the furnace core tube. An optical fiber base material is provided with a base material support rod that supports the porous base material that is inserted into the reactor core, and a sealing lid that is provided at the top of the reactor core tube and provides a gas seal between the reactor core tube and the base material support rod. In the manufacturing apparatus, on the top of the seal lid,
A glass sliding plate having a through hole through which the base metal support rod of the lid is passed has an inner diameter smaller than the inner diameter of the through hole through which the base metal support rod is passed, and is slidable in a direction perpendicular to the longitudinal direction of the base metal support rod. An apparatus for manufacturing an optical fiber base material, characterized in that: (2) The apparatus for manufacturing an optical fiber base material according to claim 1, wherein a sealing material containing graphite as a main component is interposed between the sealing lid and the glass sliding plate.
