PURPOSE:To ensure that an electric apparatus is not damaged by molding integrally a rear cylinder for storing the flying-out preventive device for contents such as gas, etc., of the same diameter as a front cylinder through a partition plate at the rear end of the front cylinder. CONSTITUTION:A columnar aluminum material 24 is plugged to the front end of the projection 29 of the die 28 having the outside diameter approximately the same as the inside diameter of the rear cylinder 23 of a diameter smaller than the front cylinder 21 of the aluminum case set at the center of the small diameter port 27 succeeding the large diameter port 26 of the die ring 25 having the diameter approximately the same as the outside diameter of the front cylinder 21 of the aluminum case to become a product. By pressing this in the arrow direction by the punch 30 having the outside diameter approximately the same as the inside diameter of the front cylinder 21 of the aluminum case, the rear cylinder 23 of the diameter smaller than that of the front cylinder 21 is molded integrally through a partition plate 22 at the rear end of the front cylinder 21.
