<P>PROBLEM TO BE SOLVED: To prevent a boiled-over object from remaining and sticking in a groove part with respect to a gas cooking stove, wherein an annular raised area part 32 to which an annular trivet frame 61 of a trivet 6 is externally fitted is formed on a top plate 3 by drawing while being positioned at a peripheral edge part of a burner opening 31, and a groove part 33 recessing inward along a radial direction is formed on an outer peripheral surface of the annular raised area part 32, and a protruding part 63 provided to the trivet is engaged with the groove in a way that rotation of the trivet is prevented. <P>SOLUTION: A protrusion receiving seat 34 is formed on the top plate 3 by drawing so as to protrude outward in a radial direction from lower parts at a plurality of points of the outer peripheral surface of the annular raised area part 32 where no groove part 33 has been formed. The trivet frame 61 is seated on the receiving seat 34 to assure a gap between the trivet frame 61 and the upper surface of the top plate portion adjoining an outer end part in the radial direction of the groove part 33. <P>COPYRIGHT: (C)2013,JPO&INPIT |
