PROBLEM TO BE SOLVED: To provide a glass preform suspension device, in suspending a starting member or a glass preform, capable of closely (strongly) connecting a suspension shaft tube and a suspension member and aligning the centers of the suspension member and the glass preform in the vertical direction.SOLUTION: A glass preform suspension device is used for an apparatus for manufacturing an optical fiber glass preform or an apparatus for drawing an optical fiber, and comprises a suspension shaft tube for suspending a starting member or a glass preform. The suspension shaft tube has a horizontal hole passing through the central axis on the body side, and a suspension member on the upper part of the starting member or the glass preform; and the suspension member has a horizontal hole having an inclined planer portion. The suspension shaft tube and the suspension member are connected by inserting the suspension member into the suspension shaft tube, and adjusting the positions of both horizontal holes and inserting a pin through both horizontal holes. |
