2. Description of the Related Art The structure of a conventional flyback transformer device is shown in FIG. As shown in the figure, the high-voltage lead wire 12 is connected by piercing the conductive rubber 14 with the core wire 13 of the high-voltage lead wire 12 (in the case of a stranded wire, the tip is hardened by soldering). Since it can be easily pulled out as it is, the lead holder 10 made of silicon rubber or the like is used.
It is held by the frictional force of 2 and the frictional force between the lead holder 10 and the cylindrical portion of the insulating case 15.

However, in the above-mentioned structure, since the high voltage lead 12 is only held by the frictional force, a sufficient holding force cannot be obtained. Therefore, the length of the contact portion between the lead holder 10 and the high-voltage lead wire 12 and the length of the contact portion between the lead holder 10 and the tubular portion of the insulating case 15 are increased to increase the frictional force. Although it may be increased, there is a problem that the total length of the lead holder 10 becomes long, which leads to an increase in cost. Further, it is conceivable to bond the lead holder 10 and the high-voltage lead wire 12 and the lead holder 10 and the cylindrical portion of the insulating case 15 using an adhesive or the like, but there is still a problem that the cost is increased and the number of work steps is increased. is there.
