PROBLEM TO BE SOLVED: To provide a gas cooking stove that suppress the radiation of combustion gas heat from a trivet and improves heat efficiency. SOLUTION: A trivet ring 21 has a double structure comprising a front plate 21a opposing a cooking container and a back plate 21b opposing a drip pan and a top plate. Ceramic 21e as a heat insulating material is sandwiched by the front plate 21a and the back plate 21b at each of the entire outer peripheral edge and the entire inner peripheral edge, and caulked and fixed at four locations at each of the outer peripheral edge and the inner peripheral edge. By this constitution, a gap formed between the front plate 21a and the back plate 21b works as a heat insulating layer, and burner combustion gas heat transferred to the front plate 21a is not radiated to the outside. Therefore, the combustion heat of the burner is efficiently transferred to the cooking container and heat efficiency can be improved. COPYRIGHT: (C)2009,JPO&INPIT
