ABSTRACT:
In assembling an electron gun (10), parts (11 to 18) are placed on supports (21) on the support base (2). The angle of a supported G3 grid (15) can be adjusted by moving the side of the G3A grid (15A), because the support (21) for the G3 grid (15) holds only the rear of the G3B grid (15B). Accordingly, in the event the G3A grid (15A) and the G3B grid (15B) are welded together out of position, adjuster pins (5) can be inserted into the guide holes (61) of the G3A grid (15A) without being bent, thereby adjusting beam holes (62) of G3A grid (15A) to coincide with the beam holes (62) of other grids. Accordingly, the beading apparatus (1) allows the electron gun (10) to be manufactured with considerable precision.
