To mold a wheel for a vehicle with high quality having no blowhole by pressure casting with high productivity even when the cross sectional area of a connection part for connecting an outer circumferential rim with the hub of a central part is small.
When casting the wheel for the vehicle having the hub 21 of the central part, the rim 22 of an outer circumferential part and the connection part 23 for connecting the hub 21 with the rim 22, a cavity 8 for molding the wheel in a posture which makes a wheel axis C almost horizontal is formed inside a molding die 1 that opens/closes in an almost horizontal direction. A molten metal 4 is pressurized and injected into the lowermost part 8d of a rim forming part 8a in the cavity 8, a pushing-in pin 7 is advanced from an axial direction to the central part of a hub forming part 8c in the cavity 8 at the midway of the solidification of the molten metal 4, and the solidification of the molten metal 4 is completed in such a state.
