Further, since the PTC heater 20 is urged by the conductive spring 24, for example, the PTC heater 20 or the like is inclined and assembled in the assembly process, or the contact surface of the PTC heater 20 or the like is not flat and uneven. Even if the flatness increases due to deformation (warping or the like) of the PTC heater 20 caused by molding, deformation of the partition wall 17 of the case 11 due to adjustment marks, waviness due to processing, etc. A good contact area of the PTC heater 20 with respect to the partition wall 17 side that partitions the temperature sensing portion 13 of the element can be obtained.

- the case 11 and the like are formed of a metal material having good thermal conductivity
- the thermal expansion body 12 such as wax is formed of a material that changes in volume with a temperature change, and other parts are Since it has a conventionally well-known structure, the details are omitted here.
- the temperature-sensitive actuator 10 having the above-described configuration is characterized in that the contact member 40 is provided so as to be interposed between the temperature-sensitive portion 13 of the thermoelement and the PTC heater 20.
- the contact member 40 a copper-based material having excellent thermal conductivity may be used. Needless to say, the contact member 40 may be of any appropriate shape and material having an appropriate volume.

Heat transfer to 11 can be performed.
- the PTC heater 20 can continue to generate heat efficiently as much as the PTC heater 20 receives heat, so that the output of the PTC heater can be stabilized. It is something that can be done.
- the heat from the PTC heater 20 is transmitted to the contact member 40 and is transferred to the thermo-element temperature sensing unit 13 via the contact member 40.
- the PTC heater 20 does not transfer heat to the surrounding members, for example, the element case 11, etc.

- the contact member 40 described above receives the amount of heat generated by the PTC heater 20, the PTC heater 20 continues to generate heat efficiently. Therefore, the thermo element operating time is longer in the initial energization period than when there is no contact member. However, it is possible to transfer heat to the temperature sensing unit 13 for a certain period of time even after the energization is stopped, so that the energization amount can be suppressed and energy saving can be achieved. Further, once the temperature of the contact member 40 rises and the contact member maintains a certain amount of heat, the output of the PTC heater 10 becomes stable, and the thermo element can be continuously operated in a required state.

- the performance as the temperature-sensitive actuator 10 can be improved. Moreover, such performance improvement is obtained by the heat retention effect and heat storage effect by the contact member 40, and its practical effect is clear. In other words, this effect is due to the fact that heat can be smoothly transferred by the contact member 40 and the PTC heater 20 can stably maintain a high output.
- the contact member 40 has a shape that does not have a contact portion, for example, a space (or a depression) in a part on the side that contacts the thermo element, in particular, the central portion on the side that contacts the thermo element. This is a case where it is formed to have a ring shape.
- the temperature-sensitive portion 13 of the thermo-element is manufactured at a temperature-sensitive thermo-element lift amount due to subtle differences in the assembly method and the amount of wax 12 enclosed during manufacture. It is well known that individual differences (variations) occur every time. For this reason, conventionally, in order to suppress this type of variation, as an indispensable step in the manufacturing process, the bottom surface portion of the case 11 of the thermoelement is recessed after assembly, and the enclosing chamber for the wax 12 in the thermoelement case 11 is forced. In general, the protrusion length of the piston 14 is forcibly adjusted by pushing it in, so that the lift amount by the thermo element is generally adjusted to a reference value.
- an adjustment mark 43 due to adjustment is formed on the bottom surface (partition wall 17) of the thermo element case 11, and various adjustment marks 43 of various sizes are generated depending on the degree of adjustment.
- the contact member is formed to have a ring shape, so that the bottom surface (partition wall 17) of the thermoelement case 11 and the contact member regardless of the presence or absence of the adjustment marks 43 described above.
- the contact area with the contact member 40 and the contact area between the contact member 40 and the PTC heater 20 are made constant so that the amount of heat transmitted to the thermo element and the energization amount of the PTC heater 20 can be made constant regardless of the size of the adjustment mark. ing.

- the hole of the ring-shaped contact member 40 is larger than the adjustment mark 43 on the case bottom (partition wall) of the thermosensitive part 13 of the thermoelement and does not overlap the adjustment mark 43, Regardless of the size of the adjustment mark 43 at the bottom of the case 11 of the thermoelement, the contact area between the bottom surface of the case 11 of the thermoelement and the contact member 43 and the contact area between the contact member and the PTC heater 20 are made constant and transmitted to the thermoelement. Since the amount of heat and the energization amount of the PTC heater 20 can be made constant regardless of the size of the adjustment mark 43, the lift amount for each product can be eliminated.
- FIG. 5 shows yet another embodiment of the present invention. That is, in the above-described embodiment, as shown in FIG. 2 or the like, the temperature-sensitive actuator 10 is provided by fitting electrode terminal fittings 31 and 32 with leads 33 and 34 on the outside of the case 11.
