Claims

[Scope of utility model registration request]

A heater is attached to the outer surface of the temperature sensing part 1a of the thermoelement a, in which a piston 3 that can be fitted into a guide cylinder part 1b provided in the body 1 moves in and out as the temperature sensing material 2 sealed in the temperature sensing part 1a of the body 1 expands and contracts. h is heat-transferably assembled, a pressure-sensitive element b is integrally assembled to the piston 3 which is actuated by the output of the thermo-element a, and the pressure-sensitive element b and the body 1 of the thermo-element a are integrally assembled. An elastic member 9 that presses the pressure sensing element b in the opposite direction to the extending direction of the piston 3 is placed between the frame 7 and the attached frame 7, and the elastic force that presses the pressure sensing element b corresponds to the amount of operation of the piston 3. 1. A thermoelement actuator, characterized in that the thermoelement actuator is arranged such that the resistance of the pressure sensitive element b changes accordingly, so that driving of the heater h can be controlled by changing the resistance of the pressure sensitive element b.
