Abstract
A method of attaching and detaching a preform to and from a support body, the preform being used to manufacture an optical fiber, the method including: inserting a connection pin through a penetration hole provided in the preform and a penetration hole provided in the support body; attaching the preform to the support body by hanging the preform on the connection pin inserted through the penetration holes; and detaching the preform from the support body by taking out the connection pin from the penetration holes after the connection pin is rotated about an insertion axis due to an action of a moment based on gravity when the hung state of the preform hung on the connection pin is released.
