Claims

[Scope of Claim for Utility Model Registration] 1. In gas appliances with a safety device that automatically ensures safety by operating a shutoff valve to shut off the gas flow path when a shutoff signal is received, a gas appliance that penetrates the case body an externally operable return shaft that is attached to the main body so as to be able to go in and out; and a return shaft that is located in the gas flow path of the case main body and that rotates about the fulcrum shaft against its own rotational habit by pushing the return shaft. A cam, which is located in the gas flow path and is normally located away from the valve seat, but in an emergency it is activated and presses against the valve seat to shut off the gas flow path, and after the emergency condition is released, the cam is located at a distance from the valve seat. A shutoff valve return structure for gas equipment, comprising: the shutoff valve that is pushed by a return cam to return to its original position. 2. Claim 1 of the above-mentioned utility model registration applied to a gas meter and arranged inside the gas inlet thereof
Shutoff valve return structure for gas appliances as described in section.
