孔７ｃを設けている。 In FIG. 2, the operation panel plate 7 is made of a thin aluminum plate and is disposed on the right side of the front surface of the microwave oven main body 8. Since the operation panel plate 7 is thin and easily deformed, it is attached to the outer surface of an operation panel (operation panel plate mounting body) 9 made of resin. As shown in FIG.
b) Furthermore, the tip of the inwardly bent piece 7b is bent inward at the tip of the mounting piece 9a to prevent the operation panel plate 7 and the operation panel 9 from coming off. The distal end of the inwardly bent piece 7b and the mounting piece 9a are fastened together by inserting a U-shaped metal mounting nut 10 shown in FIG. 3 from the distal end. The mounting piece 9a of the operation panel 9 is provided with a notch 9b for screw relief and a groove 9c for preventing rotation of the mounting nut 10, as shown by broken lines in FIG. A screw hole 10 for the nut is provided in one piece of the mounting nut 10.
A long hole 7c with a short size slightly smaller than the root diameter of the screw to be tightened to the mounting nut 10 and a long hole 7c with an arbitrary length are provided so as to match the center line between the screw escape hole 10b provided in the other piece and the short hole 7c. .

なることはない。 When the above-described operation panel assembly is installed by tightening the screws into the nut screw holes 10a of the mounting nuts 10 from the microwave oven main body 8 side as shown in FIG.
The valley and the elongated hole 7c come into contact and the operation panel plate 7 is grounded to the screw 11, and the mounting nut 10 and the inwardly bent piece 7b of the operation panel board 7 are pressed together and grounded to the mounting nut 10. The operation panel board 7 is grounded to the microwave oven main body 8 via the screws 11 and the mounting nuts 10. Since no rotational force is applied to the inwardly bent pieces 7b of the operation panel plate 7 to tighten the screws, they will not be torn or torn, and even if force is applied to the operation panel plate 7 during transportation or use of the product, the operation panel plate 7 will not operate. Since it is fastened together with the panel 9, the appearance of the operation panel board 7 will not be deformed and the product will be defective, unlike in the past.
