 Embodiments of the present invention will be described below with reference to the drawings. In the description of the present embodiment, the same reference numerals will be given to the same names as those in the conventional example, and detailed description thereof will be omitted. FIG. 1 is a perspective explanatory view of a main configuration of a deflection yoke device according to this embodiment.

The characteristic of the present embodiment is that the circuit board 20 provided on the deflection yoke is provided with the connection portions 15 for the lead wires 21 and 22 connected to the television set side concentratedly arranged at one location. Is.

A circuit board 20 is attached to the neck side of the deflection yoke device, and lead wires (not shown) of the vertical deflection coil and the horizontal deflection coil are connected to the circuit board 20.
