description PURPOSE:To form the wheel for rolling stock having a thick rise part by making the thickness of the peripheral edge part of the rim blank cylinder integrally formed on the peripheral edge part of a disk part larger than that of a root trunk part and spinning this rim blank cylinder. CONSTITUTION:A front side rim part 2 and back side rim blank cylinder 3 are integrally formed by forging or casting at the front and back side peripheral edge parts of a disk part D to obtain the wheel blank 1 for rolling stock. In said back side rim blank cylinder 3, the thickness A of a peripheral edge part 32 is formed larger than the thickness B of a root trunk part. This wheel blank 1 is fitted to a rim forming mandrel 4 and held by pressing it from the disk D side by a pressing plate 6. The mandrel 4 is rotated on the circumference of a shaft center 43 in this state and a rotary pressing tool 5 is moved in an arrow mark direction with pressing it to the rim blank cylinder 3. A back side rim part 31 is formed in the state of maintaining the thickness of a rise part 311 in the specified thickness by ironing the rim blank cylinder 3 along the forming face 41 of the mandrel 4 and the wheel W for rolling stock is thus obtd.
