Abstract
In a method of integrally attaching a hollow member to a cast product by casting so that the hollow member communicates with a hollow interior of the cast product, a closure member is fitted into an open end of the hollow member so that the open end of the hollow member is closed by the closure member. The closure member projects from a core for forming the hollow interior of the cast product in a direction different from a direction in which the core is drawn out of the cast product. A molten metal is poured into a casting mold after the casting mold has been clamped. The closure member is moved inside the core after solidification of the molten metal so that the closure member is released from the fitting in the hollow member. The core is drawn out of the solidified metal subsequently to the moving step of the closure member.
