Abstract
In a step of forming a fixing groove for a wheel disk (), an inner circumferential end of a first hub hole peripheral portion () is squeezed by a protruding portion (D) of a back die (D) and a dent portion (D) of a front die (D). In this manner, a fixing groove () is formed in a back surface of the first hub hole peripheral portion (). Along with this, an excess material is pushed into the dent portion (D) so that a protrusion () is formed on a front surface of the first hub hole peripheral portion (). Thus, without requiring a step of cutting the excess material, the fixing groove () can be formed in a back surface of a hub hole peripheral portion ().
