Abstract
A rod-shaped work made of metal is set into a forging die having a cavity where a load is applied to the rod-shaped work in the axial direction thereof and a twist is generated therein during an upset forging process so that an expanded portion is formed. This makes it possible to prevent generation of an underfill portion in the expanded portion which cannot be removed by a drawing process.
