"Problems to be Solved by the Invention" In the conventional technique, since the engagement portion is formed by cutting the chassis and squeezing (building) upward by pressing, both ends of the upper surface of the engagement portion are inevitably formed. Since the bottom plate of the inserted transformer is positioned by applying the bottom plate to the skirt portion, if the bottom plate is strongly pushed into the engaging portion, the skirt portion changes to the outside, and the bottom plate changes. Position is not determined, the screw can not be easily fixed later,
There was a problem that productivity in a mass production line was reduced.

According to the present invention, a power transformer having a bottom plate is placed on the chassis from above, and two corners of the bottom plate are engaged with the chassis. In the power transformer mounting structure in which the remaining two corners are fixed to a chassis, an inboard pedestal provided with an engaging portion for the bottom plate and an outboard pedestal provided with a screw fastening portion for the bottom plate are bulged to the upper surface side. Then, each pedestal is formed to be longer than the width of the bottom plate, and the chassis on both sides of the inner pedestal is vertically raised in a C-shape in plan view. By forming an engagement hole to fit the inside corner,
At the time of engagement, the bottom plate and the screw hole for the screw on the chassis side are aligned with each other to form an engagement portion with the bottom plate for positioning the bottom plate at a screwing position where a screw is screwed from above.

"Operation" Therefore, since the engaging portion of the chassis with the bottom plate has an engaging hole formed in the raising piece, the opening width itself of the engaging hole does not change, so depending on the strength of the force pushing the bottom plate, Since the insertion depth of the bottom plate into the insertion hole does not change, the positioning accuracy of the bottom plate can be obtained with high accuracy, and the positioning transformer can be mounted on the chassis with high positioning accuracy. The lower holes for stopping will surely coincide with each other, and after that, by simply screwing the screws from above, the power transformer can be easily and securely fixed to the chassis, and the engaging portion of the chassis side with the bottom plate,
The pedestal provided with the screw portion serves as a reinforcing rib of the chassis, and the pedestal is formed to be longer than the width of the power transformer, so that it can greatly contribute to the reinforcement of the chassis.
