<p>PROBLEM TO BE SOLVED: To provide such a structure of fitting a flyback transformer that the engaging claw of a fixation leg of a flyback transformer can be accurately engaged with a receiving hole of a board without a separate part, the generation of chatter can be suppressed to prevent noises, and the production efficiency can be improved. SOLUTION: The fixation legs 1b, 1c and 1d of a flyback transformer 1 are inserter into receiving slots 2a, 2b and 2c of a board 2 respectively, so that the flyback transformer 1 is fitted to the board 2. In such a structure, a small-width part 2h that is almost the same in width as the engaging claw 1f of the leg 1c of the flyback transformer 1 is provided at the center of the lengthwise-direction side of a top-view nearly goblet-like receiving slot 2b. When the flyback transformer 1 is fixed onto the board 2, the engaging claw 1f of the leg 1c of the flyback transformer 1 is inserted into a large-width part 2i before the engaging claw 1f of the leg 1c is engaged with the small-width part 2h of the receiving slot 2b, and then the engaging claw 1f of the leg 1c is moved and engaged with the small-width part 2h for fixation.</p> |
