１２号公報）。2. Description of the Related Art In general, in high-frequency heating devices such as microwave ovens, in order to observe the cooking state of food during cooking, there is a connection between the outer shell 1 of the device and the heating chamber wall 2, as shown in FIG. An illumination lamp 3 is provided in the space between 7' and illuminates the inside of the heating chamber 5 through a number of small holes 4 made in the heating chamber wall 2. In addition, in cases where the high-frequency heating device is used by being embedded in the wall (built-in type), in order to facilitate the replacement of the lamp 3, the lamp 3 is attached to the equipment outer shell 1 so as to be rotatable. Generally, it is attached to the window 6 via a lamp support fitting 7 (Utility Model Publication No. 59-624).
Publication No. 12).

どの問題があった。Therefore, since the lamp 3 is pulled out from the opening 9 of the outer shell 1, work efficiency is poor, and the lead wire 10 also has to be made long, which increases the cost of each lead wire. In some cases, the insulation distance between the lead wire 10 and other electrical components could not be ensured, which was dangerous. Furthermore, because the lamp 3 is not fixed during the process, if it hits other parts on the road and is damaged, or if the lamp 3 is energized during a process inspection, the lamp 3
There were problems such as the terminals touching parts of the equipment, which could cause a ground fault.

越える。In the first embodiment, when temporarily fixing the lamp support fitting 7 to the lamp cover 12, first, the hook part 11a of the lamp support fitting 7 is inserted into the corresponding opening of the lamp cover 7...7=12. 12a, and then push downward so that the claw portion 11a is caught in the opening 12a. The claw portion 11b for preventing removal is elastically deformed as the lamp support fitting 7 moves downward, and climbs over the protrusion 13 of the lamp cover 12. At this time, when the lamp support fitting 7 is completely inserted into the lamp cover 12, the deformation of the claw portion 11b for preventing removal elastically returns to its original state, so that the worker can completely complete the temporary fixing work. You can feel what has been done. The lamp support fitting 7,
When fixing to the lamp exchange window 6, when the screw 8 is tightened, the lamp support fitting 7 is pulled and the reverse operation is performed, and the claw portion 11b for preventing removal elastically climbs over the protrusion portion 13.
