とができる。Thus, the annular extending portion 2 formed integrally with the burner 1 and formed on the periphery of the burner 1 provides:
The heat from the flame of the burner 1 is received by the extension portion 2 and is conducted to the burner main body 17, thereby suppressing a rise in the temperature of the top plate near the burner 1. Therefore, the top plate 5
When a thin steel plate or aluminum plate is used, the deformation due to thermal expansion can be reduced without the need for a structure for heat insulation and heat insulation, and the surface of the thin steel plate or aluminum plate is treated with fluorine coating etc. However, the rise in the temperature of the top plate 5 can be suppressed, and the durability of the coating layer can be improved. When the top plate 5 is made of glass, expensive crystallized glass does not have to be used, and general tempered glass can be used, and the cost can be reduced. In addition, it is possible to suppress boil-over from strongly sticking to the top plate 5.

Is not required, and a relatively low heat-resistant material can be used, so that the broth or the like spilled on the top plate 5 can be reliably prevented from entering the casing 6 of the stove. It is possible to avoid soiling the inside of the car, and to improve the careability, safety and durability.
