acts not only as a holding member for airtightly holding the temperature sensitive plate 2 to the windshield 4, but also as a heat insulating material between the temperature sensitive plate 2 or thermistor 1 and the windshield 4, As mentioned above, thermistor 1
is in contact with the temperature sensing plate 2, so most of the temperature outside the watch, where the surface 2a of the temperature sensing plate 2 is in contact, is transmitted to the thermistor 1 through the temperature sensing plate 2, so the temperature of the thermistor 1 is The temperature becomes very close to the temperature of the surface 2a of the temperature sensitive plate 2. In addition, since the tip of the thermistor 1 is always in pressure contact with the temperature sensing plate 2, the temperature sensing plate 2
The heat conduction from the to the thermistor 1 is always stable, and the responsiveness of heat conduction is also improved.
なおサーミスタ１の出力を温度表示するための

The electrical connection lead 1a of the thermistor 1 is made of a thin metal wire that can be deformed with a very small force, and one end 1b of the lead 1a is connected to the circuit board 5 by welding.
またモジユールの構成部品であるスペーサ７と

力により、サーミスタ１の頭部が上記グリス６を
突き破り、その結果、サーミスタ１と感温板２と
の接触が保たれるように構成されている。 In this case, since the heat insulating cushion 8 is made of a foam material, the head of the thermistor 1 breaks through the grease 6 due to its elasticity at the same time as the cushion 8 deforms, resulting in contact between the thermistor 1 and the temperature sensitive plate 2. It is configured so that it is maintained.
