A reed switch 12 connected to an ignition device 17 is arranged in the ON position. A shutoff valve 2 of a fuel passage is arranged in the OFF position of the lever 11. In the OFF position, the magnet 14 of the lever 11 approaches a valve 3 formed with a magnetic member, and the member 3 is shifted upward within the case 4 to shut off the fuel passage. When the lever 11 is operated to shift to the ON position, the valve 3 is shifted downward within the case 4 or receives a force applied by a spring to open the fuel passage.
