When a fish grill or the like is used in this state, the exhaust heat 67 discharged from the exhaust port 61 rises directly above the exhaust port 61 as shown by the dotted line in the figure, and is discharged without hitting the wall surface 69. As a result, the temperature of the wall surface 69 does not rise excessively.

  Thus, since the exhaust port cover attachment 1 can stabilize the exhaust port cover 40 in the first position and the second position, the exhaust port 61 is usually covered with the first position to prevent the exhaust port 61 from being soiled. In the case where the exhaust heat 67 is exhausted from the exhaust port 61, the exhaust heat 67 can be moved to the second position to open the upper portion of the exhaust port 61 so that the exhaust heat 67 does not hit the wall surface 69. That is, it is possible to prevent the wall surface temperature of the wall surface 69 from excessively rising without removing the exhaust port cover mounting tool 1 and the exhaust port cover 40 each time, so that the usability is improved.
