PURPOSE:To prevent a leakage of microwave and improve a heat insulation of the cooker device by a method wherein a gasket of semicircular heat-resistant resilient body is arranged along the inner wall of the door, while its one side is fixed between the door inner wall and the sealing wall. CONSTITUTION:Only a side end surface of the gasket 14 of semi-circular section composed of a heat-resistant resilient body is held between the door inner wall 8 and the edge of the groove in the sealing wall 9 so as to cause the pressure to be released when the door 3 is closed at a non-fixed part. With this arrangement, when the door is closed, the gasket 14 is collapsed by a slight pressure, so that even if the cooker is designed such that a height of the gasket 14 is higher than the door inner wall 8 with the door 3 being opened to have an effect against a clearance as big as possible, it is possible to prevent an occurrence of clearance between the door inner wall 8 and the front wall 15 of the heating chamber. Thus, it is possible to improve a heat insulation effect. |
