Abstract: PROBLEM TO BE SOLVED: To eliminate failure such as leakage by a method wherein a joint forming part is integrally built on a tank component member and a surface for binding other members thereon of the joint forming part is scraped while a screw hole is worked therein to apply an impregnant on at least the scraped surface thereof. SOLUTION: A joint part 4 is formed integral on a tank component member 10. The tank component member 10 is formed by casting or forging. At the same time, a joint forming part 11 is integrally formed on the tank component member 10. A surface 12 for binding other members thereon of the joint forming part 11 is scraped to be formed into a flat surface with a specified surface roughness. As a cavity is apt to be developed on the scraped surface 13, an impregnant is applied at least on the scraped surface 13. Because the applying of the impregnant is an attempt to prevent the leakage by filling the blow, the impregnant can be applied on the rear 17 side of the scraped surface 13 from a point of view of preventing the leakage. Moreover, the integral formation of the joint part 4 on the tank component member 10 allows cutting of an installing space.
