Abstract
The burner case has a first member having a caulking portion and a second member having a facing portion facing the caulking portion and an extending portion for caulking, the extending portion extending from the facing portion, the caulking portion being held between the facing portion and the extending portion by bending the extending portion. A part of the extending portion in longitudinal direction constitutes a claw portion. Thus, the first member and the second member are not required to be screwed or the number of screws is reduced, thereby improving productivity of the burner case and reducing the production cost of the burner case.
