式熱感知器の構造。 An air chamber is formed by a heat-sensitive plate, a diaphragm, and a diaphragm support plate, and the air that expands due to a slow temperature rise is leaked by a leak means, and the diaphragm is displaced by the air in the air chamber that expands due to a temperature rise due to a fire, thereby detecting a fire. In the differential heat sensor, the leak means includes a lid made of a thin metal plate having a hole and a pore formed in a position of a diaphragm support plate where the diaphragm is not placed, and closing the hole. A structure of a differential heat sensor characterized by comprising:
