To provide an improved method for manufacturing a wheel disc enabling reduction of manufacturing processes when compared with a conventional method and having no tool scratch on a surface facing the outside.

At step 102, a partially formed disc 132 having a pocket part 138 completely formed by stamping machining is directly formed from a flat blank 130 to dispense with first stamping operation 12 accompanied with formation of a conventional bowl-shaped disc 32. Moreover, by using a connection ring 194 at step 102, the wheel disc 132 is manufactured without causing "tool scratch" existent on an outer side face of a conventional wheel disc 52 on an outer side face of the disc 132.
