Summary:PROBLEM TO BE SOLVED: To manufacture a high quality optical fiber by suppressing the vibration, etc., of an optical fiber preform. SOLUTION: The apparatus for manufacturing optical fibers which manufactures the optical fiber 3 by heating and drawing the optical fiber preform 1 in a fiber drawing furnace 5 is provided with a piezoactuator 12 between a clamper 7 for clamping the head part of the optical fiber preform 1 and a base 8 of the clamper for supporting the clamper 7. The clamper 7 is provided with strain gages 10s for detecting the deviation of the weight of the optical fiber preform 1. A controller 20 detects the misalignment of the optical fiber preform 1 from the strain gages 10 and displaces the clamper 7 by driving the piezoactuator 12, thereby correcting the misalignment, such as inclination, of the optical fiber preform 1.
