Abstract
A steering-wheel core and a method for casting the same capable of eliminating the need to perform finishing processing after casting and decreasing manufacturing cost even when the steering-wheel core is cast using a molten metal. The method for casting a steering-wheel core () includes: providing a protruding portion () in a surface () of an inner surface of a casting die (), with the surface defining a nut seat surface; and causing a molten metal to hit on the protruding portion () when the molten metal flows into the casting die () such that a change occurs in the flowing direction of the molten metal flowing toward the surface () that defines the nut seat surface.
