り手数がかゝり、接続不良になる虞がある。<Problem to be solved by the invention> In order to clip the end of the high voltage terminal with the clip pin, the end of the high voltage terminal is pressed against the question mark-shaped or U-shaped part of the pin. Since the pin is only fixed to the flange of the secondary bobbin at one end, it is unstable because it bends due to elasticity when pressed, and it takes a considerable amount of effort to engage it accurately, resulting in poor connection. There is a possibility that this will happen.
