Zusammenfassung:	PURPOSE: To certainly mold a cover integrated foam molded object having a regular shape by sufficiently expanding a cover. CONSTITUTION: A molding wire 30 made of a shape memory alloy is attached to the interior of the cover 10 housed in a mold 50 along the seam 18 thereof. When a foamable filler 20 is injected into the cover 10, the molding wire 30 heated by the heat of the foaming reaction of the filler is deformed to be restored to a memory shape and the cover 10 is expanded into a predetermined shape by the restoration force of the wire to come into close contact with the inner wall of the mold 50. Since the molding of the cover is performed by the shape restoration force of the shape memory alloy stronger than the foaming expansion force of the foamable filler 20, the cover 10 can be certainly expanded into a regular shape.
