<p>PROBLEM TO BE SOLVED: To prevent floatation of an insulating case of a variable resistor for high voltage. SOLUTION: Stepped parts 15 for engaging are formed on wall parts 12a and 12c of a wall part 12 (12a-12c) for fitting an insulating case 11 of a variable resistor 10 for high voltage, and a protruding part 14 is formed as an engaging part for reinforcement on a wall part 12b. A penetrating hole 26 is formed as a part to be engaged for reinforcement in an expanded part 25b1 formed on a wall part 25b of a raised wall part 25 positioned outside a trench part 23 for fitting a transformer case 20, and protrusions 27 for engaging are formed on wall parts 25a and 25c. The wall part 12 for fitting the insulating case 11 is fitted into the trench part 23 for fitting the transformer case 20, the stepped parts 15 for engaging are engaged with the protrusions 27 for engaging, and the protruding part 14 is engaged with the penetrating hole 26.</p> |
