<p>PROBLEM TO BE SOLVED: To provide a transformer of a power source device wherein the rotation of a coil component relative to a middle leg of a core is prevented using a simple structure, and a clearance which causes troubles such as vibration and abnormal noise is not formed between the middle leg of a core and the coil component. SOLUTION: A transformer 1 which enables a rotation preventive means to be installed between a middle leg 11a of a core 10 and a coil component 20 for preventing them from rotating, can be obtained by making the cross-section of the middle leg 11a of the core 10 and a shape of a core insertion hole 22 of a coil component formed into non-circular shapes, such as oval shapes of almost the equal sizes and rounded polygon.</p> |
