The purpose of the present invention is, in a stove burner which comprises a burner head (3), a mixing tube (5) connected to the burner head, and a gas nozzle (6) having a nozzle hole (6a) that emits fuel gas toward an inlet (5a) of the mixing tube and which is provided with a cylindrical air damper (7) that restricts the amount of primary air drawn into the mixing tube, to align the central axis of the air damper with the axis of the nozzle hole and thereby emit an air-fuel mixture with a uniform air-fuel ratio from a plurality of burner ports (3a) on the outer circumference of the burner head. The basal end of the air damper (7) is mounted to the gas nozzle (6), and the central axis of the air damper (7) is aligned to the axis of the nozzle hole (6a). In addition, primary air is drawn into the mixing tube (5) via a gap in the axial direction created between the distal end of the air damper (7) positioned further toward the axial distal end than the gas nozzle (6) and the inlet (5a) of the mixing tube (5). |
