Abstract

PURPOSE:To prevent the shape of an electron gun frame body from being deformed due to thermal and stress deformation by welding and fixing one cathode eyelet support body to the other cathode support eyelet support body to which the cathode support eyelet is welded and fixed. CONSTITUTION:Two cathode support eyelet support bodies 5C1 and 5C2 which support and fix the cathode eyelet support body of the center section are formed in such that the curved sections 5C1' and 5C2' closely holding the circumferential surface of the eyelet 4C are different in length and the arm sections 5C1'' and 5C2'' of the support bodies 5C1 and 5C2 are closely facing each other. Then the eyelet 4C is welded and fixed to the support body 5C1 in its curved section 5C1' (marked by X) and the support bodies 5C1 and 5C2 are welded and fixed together at the position between the arm sections 5C1'' and 5C2'' (marked by X). Thus, an electron gun frame body without any deformed configuration at cathode can be obtained.
