Claims

[Scope of utility model registration request]

In a flyback transformer in which a pair of U-shaped cores are joined facing each other, one joint part is arranged inside a case housing a coil inside, and the other joint part is arranged outside the case, the pair of A connecting piece of one of the U-shaped cores is provided so as to protrude from opposite sides of both side walls of a core guide frame that is continuously formed at one end of the low-pressure bobbin arranged in the case. A pair of connecting pieces of the other U-shaped core of the pair of U-shaped cores are erected from the bottom surface of the case so as to sandwich the connecting piece from the sides while holding the connecting piece using a plurality of jetties. The protruding piece is pressed and held using a spring piece which has a concave part that presses the upper surface of the connecting piece approximately in the middle and is fixed and held so as to press the other U-shaped core in the direction of the joint part. A flyback transformer characterized by:
