PURPOSE: To obtain a gasket which is excellent in resistance to plasticizer migration, moldability and inhibited from emission of hydrogen chloride, when it contacts with carbon and is useful for a refrigerator by molding a resin composition containing a vinyl chloride resin, a polyester plasticizer, calcium carbonate and a wax lubricant. CONSTITUTION: This gasket is obtained by molding a resin composition mainly comprising 100 pts.wt. of a vinyl chloride resin, 60-120 pts.wt. preferably 70-110 pts.wt. of a polyester plasticizer, 70-250 pts.wt., preferably 80-220 pts.wt. of calcium carbonate (preferably soft calcium carbonate of fine particles having 0.1μm average particle size), and 0.5-4 pts.wt. of lubricant, for example, paraffin wax, or PE wax.
