PROBLEM TO BE SOLVED: To obtain a supporter for hanging a preform for optical fiber that can prevent the deformation of a pin without adverse effect on the part supporting the pin and can support the porous preform for optical fiber without inclination to the perpendicular line of a main axis. SOLUTION: A mobile type connector 17 is fitted to a diameter-expanded part 4a at the bottom edge of a main shaft 4. The diameter-expanded part 4a and the mobile type connector 17 are connected by a pin 12 so that the mobile type connector 17 may be swingable around the pin 12 as the center. A handle 14 for holding the diameter-expanded part 4a at the top end of the starting parent material 7 is integrally set at the lower part of the mobile type connector 17. The diameter of the pin 12 is set in the range of 25-50% of the diameter at the place where the pin 12 through which the pin 12 passes in the diameter-expanded part of the lower end of the main axis.
