PURPOSE:To improve strength of an adjacently provided section of a disc part and a rim part by wrapping through casting a connecting member covering from the disc part to the rim part of a wheel cast in one body with its disc part and rim part. CONSTITUTION:A connecting member 29 is arranged on a line of demarcation between a rim part casting space 33 and a disc part casting space 35 of a mold 31. The melted metal is poured from a pouring gate 37 into casting spaces 33, 35 to wrap the connecting part 29 through casting. Strength of an adjacently provided section of the disc part and the rim part can be improved by this structure. |
