<P>PROBLEM TO BE SOLVED: To finely adjust a primary air amount supplied to a burner in a gas nozzle for a cooking stove burner which includes a nozzle body 30 having a nozzle hole 31 from which a fuel gas is blown out to an inlet 21a of a mixing tube 21 of the cooking stove burner 2 and a cylinder 32 protruding from the nozzle body in a shaft direction so as to surround a blow-out space of the fuel gas and further has a plurality of suction holes 33 of the primary air in a cylinder with an interval therebetween in a peripheral direction. <P>SOLUTION: A gap in a shaft direction is provided which allows primary air to be sucked into an inlet 21a between a tip 32a of a cylinder 32 and an inlet 21a of a mixing tube 21. In addition, a damper cylinder 34 is provided which is externally fit to the cylinder 32 so as to be turnable. A plurality of air adjustment holes 35 are formed at the damper cylinder 34 with an interval therebetween in a circumferential direction. To adjust the opening degree of each suction hole 33, the degree of each air adjustment hole 35 overlapping with each suction hole 33 is changed by turning the damper cylinder 34. <P>COPYRIGHT: (C)2013,JPO&INPIT |
