The socket 12 is positioned at a predetermined position. An insertion hole 16 is formed in each of the leg pieces 15, and a pair of through holes 17 are formed in the hanging portion 9b of the protrusion 9 in correspondence with the insertion holes 16. The hanging portion 9 of the protrusion 9 is located in both the through holes 17 and the insertion hole 16.
(b) A pin 18 having a substantially U-shaped plane is inserted from the outside to securely hold the socket 12 to the inner peripheral edge of the mounting opening 10 so as to allow slight relative movement (with the possibility of wobbling). As shown in FIGS. 1 and 3, when the outer box 3 is attached to the outside of the inner box 2 with the pin 18 inserted, the inner surface of the outer box 3 is close to the head of the pin 18 and faces it. The pin 18 is arranged so as to prevent the pin 18 from coming off from the insertion-locking position.

As shown in FIGS. 1 and 2, a lighting window 19 consisting of a large number of small holes is formed on the left side wall of the inner box 2 at a position facing the light bulb 13.
The light from the light bulb 13 is directed into the heating cooking chamber 1 through the heating cooking chamber 1. Further, as shown in FIGS. 1, 2, 5, and 6, a window 20 for replacing a light bulb is formed on the left side wall of the outer box 3 at a position facing the light bulb 13, and a step-shaped window 20 is formed inside the opening edge. A receiving portion 21 is provided. A pair of upper and lower receiving holes 22a and 22b are formed on one side of the receiving portion 21, and a screw hole 23 is formed on the other side. On the receiving part 21 in the replacement window 29, the lid body 24 has an annular elastic member 25 for preventing light leakage and for buffering, which is fixed to the inner surface thereof.
A pair of upper and lower protrusions 26a and 26b that engage with the receiving holes 22a and 22b are protruded from one side thereof, and in particular, the upper protrusion 26a has a side surface shape that is approximately It is formed in an L-shape, and when the lid 24 is opened, this L-shaped portion catches on the inner surface of the outer box 3 to prevent the lid 24 from falling off.
