防止できる。The gasket 8 is made of a flexible material, and the portion in contact with the drive shaft 52 is extremely flexible due to the presence of the cut 82. For this reason, the resistance of the rotation of the drive shaft 52 does not easily occur, and the resistance of the object to be heated placed on the turntable 23 when the weight is applied to the weight detecting means 6 is also unlikely. As a result, the structure of the gasket 8 can be manufactured simply and at low cost, and the existence of the gasket 8 itself can prevent the transmission of weight, thereby preventing the weight detection accuracy from being reduced.

止できる。Further, by sealing the gap between the circular hole 17 and the drive shaft 52, the hot air in the heating chamber A enters the drive mechanism case 4 to raise the temperature of the strain gauge 65 and improve the accuracy of weight detection. It is possible to prevent the motor 51 and the like from being deteriorated. In addition, the bottom plate 13 of the heating chamber housing 1 in which the gasket 8 is installed has a double structure of an annular bulging portion 15 and a reinforcing plate 16 whose central portion bulges downward in a circular shape. For this reason, the gasket 8 is prevented from being heated to a high temperature, and a decrease in durability due to thermal deterioration can be prevented.
