摘要： Improvement of a gas burner for a cooking stove for conducting a mixed gas to burner ports through a gas passage (18) from a mixing pipe (5) in which fuel gas jetted from a nozzle and led to the pipe and primary air sucked in accordance with the inflow of the gas, are mixed as a gas mixture, and burning the gas. A sub-chamber (Ca) is provided separately from the gas passage in order to retain the gas mixture while allowing it to flow. The sub-chamber (Ca) is connected to the gas passage (18) through an induction port (3) and the stored gas mixture is ejected from discharge ports (2) formed near the burner ports. In this constitution, an adjustable lever of the gas burner for a cooking stove is operated to quickly control the gas volume from a large quantity of gas to a small quantity of gas and eject the gas mixture stored in the sub-chamber (Ca) from the discharge ports (2) to continue burning, even when it has become difficult to continue to burn the gas in the burner ports due to rich air.
