Claims

[Scope of utility model registration request]

a first control electrode housing having a cylindrical shape with a bottom; an aperture for passing an electron beam formed on the bottom surface of the housing; a contact portion that contacts the bottom surface within the housing; and a contact portion from the contact portion to the housing. a spacer comprising legs extending toward the open side of the body; a cathode support to which a cathode sleeve is attached;
In an electron gun having a retainer that presses the cathode support so as to come into contact with the leg portion of the spacer and is spot welded to the housing, a cut-and-raised piece that elastically biases the cathode support against the retainer. An electron gun characterized by being provided with.
