Abstract

A gas seal mechanism is provided to prevent the flowing of air and gas in the furnace from inside to outside and outside to inside. A fiber drawing apparatus that melting a fiber drawing rod, which is made by fusing one end of the preform onto a handle, to thinner its diameter and draws a optical fiber. The fiber drawing apparatus comprises: a furnace for taking in the preform from the open part for fusing, a handle seal is installed on the open part of the furnace for keeping the ambient gas around the handler from flowing, and a preform seal installed between the furnace and the handle seal in the longitudinal direction of the preform for keeping the ambient gas around the preform from flowing.
