PURPOSE: To prevent a steady brace from being piled up on a mounting plate by providing an internal thread in a vertical part formed by bending vertically downward an external part extending from the end part of the mounting plate of a unit receiving plate, bending an upper part toward the mounting plate at an obtruse angle, providing a linear screw hole in a lower part and screwing an external-thread screw into the internal thread. CONSTITUTION: A mounting plate 5 for a power supply unit is placed on a unit receiving plate 21 fixed to a housing. An internal thread 22 is provided in a vertical part 21a formed by bending nearly vertically downward the part of the unit receiving plate 21 extending outward from the end part of the mounting part 5. The upper part of a steady brace 23 made to abut on the vertical part 21a is bent toward the mounting plate 5 at an obtruse angle to provide a bent part 23a. In the linear part of the steady brace 23, a long hole-form screw hole 24 having a linear part is provided. The center line of the screw hole 24 in the direction of the length is nearly vertical, and a fixing screw 25 is passed through the screw hole 24 to be screwed into the internal thread 22 to press down the end part of the mounting plate 5 by the bent part 23a. Therefore, the steady brace can be easily positioned. |
