Patent number: 8201434Abstract: A primary intermediate formed article is formed into a substantially columnar shape. A secondary intermediate formed article is obtained by piercing a preliminary hole in the primary intermediate formed article such that a radial thickness of a prospective cam top part is larger than a radial thickness of a prospective cam base part, and by forming a positioning part. The positioning part is brought into contact with a tertiary intermediate forged article forging die so as to be positioned, and the secondary intermediate formed article is pressed and forged to form a tertiary intermediate forged article including a cam top, a cam base, and a deformed hole formed by deforming the preliminary hole.
