description PROBLEM TO BE SOLVED: To prevent breakage of a support rod by suppressing vibration thereof even when vibration is transmitted thereto in the process of cooling a sintered optical fiber preform which is pulled up from a furnace and stood in the state of stillness after the preform is sintered and made to transparent.SOLUTION: An apparatus for sintering the optical porous fiber preform comprises a furnace wherein the preform is made to transparent by sintering; the support rod 5 which supports the preform by hanging; a chuck 4 which grips an end portion of the rod, enabling the rod to rotate; and a traverser 2 which enables the chuck to vertically reciprocate. The apparatus has a support rod-gripping part 20 which grips the support rod at the middle portion thereof when the sintered preform is pulled up over the furnace.
