Claims

[Scope of utility model registration request]

The mold for holding the small-diameter intermediate shaft portion of the tension bolt is divided into a plurality of parts in the radial direction, and the divided mold is fitted into a divided guide having a tapered inner hole. In a tension bolt manufacturing mold configured to expand in the radial direction by sliding in the direction, a compression spring is interposed between each of the divided molds to bias the entire divided mold to open in the radial direction. A tension bolt manufacturing mold characterized in that a pin is inserted between the molds so that the end surfaces of each mold are aligned on one plane.
