<p>PROBLEM TO BE SOLVED: To provide a flyback transformer wherein two and more kinds of cores can be built in the same body. SOLUTION: A core-rotation stop 8 for preventing turning the of core is provided to the outer case 7, and a step is provided to an U-shaped portion 9a of a primary coil bobbin 9. Namely, fir example, the stop 8 has a first width D1 wider than a width A1 of a first core 10, and a second core-rotation stop width D2 is wider than a width A2 of a second core 11. However the first core-rotation stop width D1 is smaller than the width A2 of the second core 11. In this way a plurality of spaces for pinching the cores are provided, to build a plurality of cores in the same body.</p> |
