PROBLEM TO BE SOLVED: To provide a mounting structure for preventing the dislocation of a flame detecting element 9 from a burner 3 due to the deformation of a plate member 42 to float from a mounting bracket 90 with the fastening force of a screw, wherein the mounting bracket 90 of the flame detecting element 9 is arranged on the outside face of a plate member 42 arranged on the side of the burner 3 and is fastened to a burring hole 421 formed in the plate member 42 with the screw 91 so that the flame detecting element 9 to be held on the mounting bracket 90 is located facing onto the burner through an insertion hole 420 formed in the plate member 42. SOLUTION: In the plate member 42, a recessed portion 422 is formed which has a tapered peripheral wall portion 422a recessed inside of a portion abutting on the mounting bracket 90. The burring hole 421 is formed in the bottom of the recessed portion 422. COPYRIGHT: (C)2004,JPO&NCIPI
