At the same time, due to the clockwise rotation of the adjusting knob 20, the intensity of the flame (ie, the gas supply amount) gradually decreases to reach the extinguishing stage.

If the adjustment knob 20 is continuously rotated clockwise over the predetermined rotation range, the operation protrusion 22 formed on the inner surface of the adjustment knob 20 is also rotated in the clockwise direction. ) And meet. More specifically, the actuating protrusion 22 reaches the bent portion 56 of the rod 53 and comes to a position where the bent portion 56 can be touched.

Then, if the adjustment knob 20 is further rotated, the rotational force acts as an external force on the rod 53 of the pressing member so that the rod 53 also rotates clockwise. At this time, the pressing piece 54 integrally formed thereon by the clockwise rotation of the rod 53 also causes the clockwise rotation, and thus the rotational force induced by the pressing piece 54 is the second of the pressing piece 54. The pressurizing portion 54b acts as an external force for pushing up the detachable lever 32.

As a result, when the detachable lever 32 is pushed up by the pressing piece 54, the detachable lever 32 is automatically raised by an elastically restoring operation of the spring 34 connected through the slide link 35. Accordingly, the gas container 13 is automatically returned to its original position, separated from the regulator 70, and returned to the normal state as shown in FIG.
