Claims

[Scope of utility model registration request]

In a thermovalve that cuts off air supply when the engine is at a low temperature and sets the air-fuel ratio to the rich side, and supplies air to set the air-fuel ratio to the lean side when the engine is at a predetermined temperature or higher, the fixed part of the valve body and A thermovalve comprising a moving part and a switch mechanism that turns on and outputs a signal when the air-fuel ratio is set to the lean side, and a display part that is activated by the output signal of the switch mechanism.
