Abstract: <P>PROBLEM TO BE SOLVED: To prevent firing from grilled fat which falls onto lower burners.  <P>SOLUTION: The grilled fat falling onto burner covers 13 in a gas grill 6 is heated to be not less than firing temperature by the lower burners 12. When a grill housing 8 is substantially sealed and combustion gas is clogged in the grill housing 8, an oxygen density in the circumference of the burner covers 13 is made to be low, so as to prevent the firing of the grilled fat. In this case, a communicative port 22 is arranged between the right and left lower burners 12, i.e., the right and left burner covers 13, the width is made to be small and is not arranged just behind the lower burners 12 and the upper burners 13. Consequently, the combustion gas generated in the lower burners 12 is not directly discharged from the communicative port 22 but temporarily collides with a partition wall 21, so as to arrive at the communicative port 22, while bypassing. Thus, the circumference of the burner covers 13 are reliably filled with the combustion gas.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
