A terminal sealed portion (30) is formed on an end portion of a hollow rod (20) made of steel. An enclosed space (32) is formed on an inner side of the hollow rod (20). At an end of the enclosed space (32), a terminal gap (32a) is formed. A volatile powdered rust inhibitor (70) is supplied in the enclosed space (32). As the volatile powdered rust inhibitor (70) is vaporized, the enclosed space (32) is turned into a rust-inhibiting atmosphere. As the vaporized component of the volatile powdered rust inhibitor (70) is adsorbed to an inner surface (32c) of the enclosed space (32), an inner surface rust-inhibiting film (71) is formed. The vaporized component also enters inside the terminal gap (32a), and forms a terminal rust-inhibiting film (72).
