PROBLEM TO BE SOLVED: To enable an annular protuberance part to be restricted against its upward displacement due to thermal expansion of a top plate during ignition at a burner in a gas cooking stove in which the annular protuberance part 34 to which an annular trivet frame is outwardly fitted is positioned at a peripheral edge of a burner opening 31 in the top plate 3 for the stove while being formed in drawing.SOLUTION: A reinforcing member 35 extending from an annular protuberant part 34 to one side of a top plate 3 is fixed to the under-surface of the top plate 3, and an engaging part 35a engaged with a gas cooking stove main body 2 is formed at an end part of one side of the top plate of the reinforcing member 35 to prevent its upper floating action. In the case that the top plate 3 is fixed with screws to a grill ceiling part 61 near the grill discharging port 32 where it is opened at the rear part, the reinforcing member 35 is extended from the annular protuberant part 34 toward the front side of the top plate 3. |
