PURPOSE:To prevent adhesive sealing compound from permeating into the gap between a screen contacting piece and an inner barrier, and to enhance the effect of close sealing, by using an adhesive sealing compound of specified viscosity. CONSTITUTION:A screen and a contacting piece are monolithically molded on the back of a door board 5. A screen contacting piece 1, having a number of punched holes 11 on it so as to observe the inside of a cooking chamber, is closely fixed to the door board 5 by welding so as to cover the opening 4 of a door board 5. The center part of the screen of a screen contacting piece 1 is depressed to the backside to form a recession part 12. An inner barrier 2 is closely fitted in the recession part 12 with an adhesive sealing compound 3 being filled between the inside of a recession part 12 and the periphery of an inner barrier 2. At this time, the adhesive sealing compound 3 with the viscosity of 250,000- 400,000cP is preferable. With such an arrangement, the adhesive sealing compound will not permeate, insufficient filling of compound will not occur in any parts, and the inner barrier is prevented from fogging. |
