  • Thermostat
    Patent number: 6819216
    Abstract: A thermostat includes a wall plate unitarily molded of thermoplastic resin, a first metal plate holding a temperature sensing section, and a second metal plate holding a cam shaft. A fulcrum of a lever and a fulcrum of adjusting plate are protected by the wall plate and they are not exposed to the outside. Since both the fulcrums are not exposed to the outside, the fulcrums are free from being touched with foreign matters. This thermostat thus prevents a temperature set therein from changing.
