Abstract
In the invention, a sheet metal-made cup-shaped material (4) comprising: a circular base plate portion (2); and a cylindrical portion (3) which extends from an outer peripheral edge portion of the base plate portion (2) in one direction along the axis of the base plate portion (2) is prepared, an annular expansion (40) that is radially outward expanded is formed in the cylindrical portion (3), and the annular expansion (40) and the cylindrical portion (3) are clampingly pressed by a rotary lower mold (5) and a flat-face forming rolling roller (16) to a degree at which the annular expansion (40) disappears, whereby the outer circumferential face (30) of the cylindrical portion (3) is flatly formed. Therefore, the axial length (h4) of a sheet metal-made back face pulley (11) is increased, and the increased axial length (h4) can be used as the effective length.
