ものである。Reference numeral 6 is a bimetal plate which is punched and formed into a circular shape. Reference numeral 7 is a cap for protecting the bimetal plate, which is crimped to the case 4. 8 is a ceramic pin for transmitting the displacement of the bimetal plate 6 to the contact opening / closing mechanism, and 9 is a disk-shaped guide having a hole through which the pin 8 penetrates, which holds the pin 8 slidably. There is. These form a thermostat mechanism and are housed in a metallic housing 10 having one end opened and the other end closed. 16 is case 4
The thermostat mechanism is housed in the housing 10 at a position higher than the opening surface of the housing 10 by a cylindrical protrusion provided on the thermostat mechanism by pressing the protrusion 16 with a jig or the like. The lead wire 15 is fixed to the housing 10 by pressing, the lead wire 15 is attached to the terminal 5 with a mold material 14 by soldering, etc., then filled and sealed, and cured and then cut.

で邪魔にならず外観上も問題がない。According to the hermetically sealed thermostat configured as described above, by providing the cylindrical protrusion 16 in a part of the case 4, it is possible to prevent the molding material 14 from flowing into the thermosensitive surface of the thermostat by pressing and fixing it to the housing 10. The material 14 can be easily filled, the number of parts is small, and the cost is low. In addition, as compared with the conventional example, since it is also molded on the outer surface of the case 4, the effect of reducing the heat effect from the outer surface can be obtained. Furthermore, since the protruding portion 16 is cut off after molding, it does not interfere and there is no problem in appearance.

である。EFFECTS OF THE INVENTION As described above, by providing the resin case forming the mechanism part of the thermostat with the projecting portion that is higher than the opening surface of the housing, it is possible to reliably press and fix and the molding material flows into the thermostat heat-sensitive surface. To prevent this, it is not necessary to seal with an O-ring or washer, and after the case is pressed with a jig or the like to fill and cure the molding material, the molding material is injected again to fill the housing opening surface. No process is required, simply pressing the protruding part that protrudes higher than the housing opening surface with a jig etc., filling the mold up to the housing opening surface at one time and hardening it does not increase the number of parts, and the process is also easy A closed thermostat can be provided, which is very useful in practice.
