PROBLEM TO BE SOLVED: To improve uniformity in distribution in a burner longitudinal direction of mixed gas injected from pilot flame burner port.SOLUTION: There is provided a burner which comprises a burner cap comprising a side plate 31 covering a burner main body from at least outside of transverse direction 1, and in which a main burner port 4 at upper edge and a main mixed gas path 5 supplying mixed gas to the main burner port are arranged between a pair of side plates 21 of the burner main body, and a pilot flame burner port 7 at upper edge and a pilot mixed gas path 8 supplying mixed gas partially flowing from the main mixed gas path via a vent hole 8a formed on the side plate of the burner main body are arranged between the side plate of the burner cap and the side plate of the burner main body. A first squeezing part 9is formed on the side plate 31 of the burner cap. A second squeezing part 9is formed on the side plate 21 of the burner main body. A curve path part 8b is defined between both squeezing parts. At least lower part of the curve path part has a narrower width than a part of pilot mixed gas path 8 below it.SELECTED DRAWING: Figure 2 |
