Abstract
A cathode ray tube has an electron gun supported on a stem of a vacuum envelope having stem pins. The electron gun includes electrodes fixed on two bead glasses, and mount supports are embedded in end portions of the bead glasses for supporting the electron gun on the stem, and a supporting member connects one of the stem pins and one of the mount supports. The supporting member includes a plate-like portion, first and second bent portions bent from respective sides of the plate-like portion to form a generally C-shaped transverse cross section, the first bent portion is welded to the one of the mount supports, and the second bent portion is welded to the one of the stem pins. An axial length of the plate-like portion on its first-bent-portion side is longer than that on its second-bent-portion side.
