Abstract
A workpiece material is fed between rollers to bend the workpiece material while rolling, wherein the workpiece has a first thickness portion and a second thickness portion connected to each other with a setting angle of 90 degrees. The first thickness portion increases from an inner side toward an outer side, and a thickness on an outer peripheral side of the first thickness portion is M, and a thickness of a cross section of the second thickness portion is N. The workpiece material is rolled in such that at a completion of bending, a thickness of a cross section of a first thickness portion is m, an outer radius of the first thickness portion is R, an inner radius of the first thickness portion is r, and a thickness of a cross section of a second thickness portion is n, and M equals to m(R/r), and N equals to n(R/r).
