1. A glass base material hanging mechanism that is used in an optical fiber glass base material manufacturing apparatus or an optical fiber drawing apparatus, the glass base material hanging mechanism comprising:
a hanging shaft tube that is for hanging a starting member or glass base material and that has a horizontal hole formed in a side portion thereof passing through a central axis thereof; and a hanging component that is positioned above the starting member or glass base material and that has a horizontal hole with an inclined flat surface, wherein the flat surface is formed in a top surface of the horizontal hole in a manner to be inclined relative to a horizontal plane in a cross-sectional plane orthogonal to a direction in which the horizontal hole extends, the hanging component is inserted into the hanging shaft tube, both of the horizontal holes are aligned and a hanging pin is inserted through the horizontal holes to connect the hanging shaft tube and the hanging component such that a side surface of the hanging component is in contact with an inner surface of the hanging shaft tube, and a vertical hole center of the hanging shaft tube is provided at a position offset from an outer diameter center of the hanging shaft tube.
