時劣化することを有効に防止できる。According to the present invention, the turntable-equipped fire has a gasket installed on the lower surface of the bottom plate of the heating chamber housing to seal between the inner periphery of the hole of the bottom plate and the outer periphery of the drive shaft. For this reason, it is possible to prevent hot air from leaking below the bottom plate, exposing the rotary drive mechanism and the weight detecting means to high temperatures, which lowers the detection accuracy and causes a failure. In the structure according to claim 2, the gasket is formed of a plate material of fluorine-based or silicon-based rubber or resin having excellent heat resistance and a small friction coefficient, and the round hole having a diameter smaller than the outer circumference of the drive shaft and the round hole. It has a shape with radial cuts. For this reason, the gasket has excellent heat resistance and durability, and the radial notch portion expands the diameter to contact the outer periphery of the drive shaft, which can effectively prevent hot air from entering the underfloor, and prevent a decrease in weight detection accuracy. . In the structure according to the third aspect, since the bottom plate of the heating chamber housing to which the gasket is attached has a double structure, it is possible to effectively prevent the gasket from becoming hot and deteriorating with time.
