ABSTRACT:
In a flyback transformer having a focus pack, in order to facilitate the manufacture and assembly of the focus pack, the focus pack mounted on the flyback transformer is constituted by an outer case portion and an inner case portion, and the outer and inner case portions are coupled to each other by a coupling portion and integrally formed. The inner case portion contains a circuit board having a resistor circuit for setting a focus adjusting voltage and a screen adjusting voltage. A focus insertion hole and a screen insertion hole are formed in the coupling portion. A focus shaft for variably setting a focus adjusting voltage is rotatably fitted in the focus insertion hole. A screen shaft for variably setting a screen adjusting voltage is rotatably fitted in the screen insertion hole. An insulating casting resin is injected between the gaps between the outer and inner case portions.
