PROBLEM TO BE SOLVED: To provide a seal structure between a cooking stove burner and a top plate portion capable of preventing intrusion of broth spilling over a top face of a top plate portion from entering into a burner insertion port.SOLUTION: A gas cooking stove includes a cooking stove burner 2 and a top plate portion 11 of a cooking stove body, and a burner insertion port 12 is formed on the top plate portion 11. An upper end portion of the cooking stove burner 2 is inserted to the burner insertion port 12, and a clearance 13 having the annular shape in a plane view, is formed between an inner peripheral edge 12a of the burner insertion port 12 and an outer peripheral edge 25 of the upper end portion of the cooking stove burner 2. An annular burner ring 5 covering the clearance 13 in the plane view, is disposed on the top plate portion 11. A weir portion 6 is disposed around the burner insertion port 12 on the top face of the top plate portion 11. An accommodation portion 55 capable of accommodating the weir portion 6 is disposed on a position corresponding to the weir portion 6, of a lower face of the burner ring 5. An inner face clearance L1 in the inside and outside direction of the burner insertion port 12 of the accommodation port 55 is longer than a length L2 in the inside and outside direction of the weir portion 6 by a prescribed length.SELECTED DRAWING: Figure 3 |
