1-3. Effect The gas stove 1 has a rear plate portion 40, which forms a part of the top plate portion 4, an annular upper surface portion 43 disposed behind the upper surface portion of the top plate main portion 20, A first covering portion 41 covers an end from above and a second covering portion 42 covers the second frame portion 32 of the frame 30 from outside. With such a configuration, the region where the gap between the rear plate portion 40 and the portion (the second frame portion 32) arranged near the rear plate portion 40 in the frame body 30 is reduced or eliminated is reduced. This makes it easier to prevent broth or the like from entering the gap between the rear plate 40 and the frame 30. In addition, since the remaining of the broth or the like is less likely to occur, the appearance can be improved.

  Furthermore, the reinforcing plate portion 89 includes a frame member 84 (first reinforcing plate portion) fixed to one side in the left-right direction of the top plate main body 20, and an end on the other side in the left-right direction of the top plate main body 20. And a frame member 85 (second reinforcing plate portion) fixed to the side. The frame member 84 (first reinforcing plate portion) and the frame member 85 (second reinforcing plate portion) have rear extending portions 84A and 85A extending rearward from the rear end of the top plate main body 20. Have. The rear extending portions 84A and 85A of the frame members 84 and 85 support the rear plate portion 40 from below.

  With this configuration, since the rear plate portion 40 can be supported from below by a part of the reinforcing plate portion 89, the force applied from the rear plate portion 40 is distributed to the frame 30 and the reinforcing plate portion 89. Can be. That is, the rear plate 40 can be supported by at least the frame 30 and the reinforcing plate 89. Therefore, it is possible to suppress the bending of the frame body 30 due to the second frame portion 32 being pressed from above by the rear plate portion 40, and it is possible to further increase the strength.

  Further, the annular upper surface portion 43 includes a flat surface portion 45 arranged along the second frame portion 32 and having an upper surface configured as a flat surface. And the 2nd covering part 42 has the structure which falls from the edge part of the flat surface part 45.

  By doing so, the shape of the annular upper surface portion 43 near the boundary on the second coating portion 42 side can be reduced to a shape with few recesses, and it becomes easier to prevent the accumulation of boiling juice and the like.
