Abstract

A rolling device (11) capable of forming and opening a clearance (33) for rolling, wherein a material (35a) having a cross-section diameter varying in axial direction is formed, and a tapered finished product (35b) is formed of the material (35a) by die forging, whereby a reduction ratio of the cross-sectional area of the material (35a) formed by die forging is less than that obtained by forming a material having a cross-section diameter uniform in axial direction by die forging only and, in addition, the finished product (35b) can be formed in a short time and thus a tapered body excellent in characteristics and quality can be formed at a low cost.
