<p>In order to configure a thermostat device to be attached to a vehicle (engine or the like) by a simple structure with a required minimum number of components and improve the assembly performance thereof, the thermostat device is provided with a casing (2) which comprises a first coolant flow path (2B), a second coolant flow path (2D), and a thermostat accommodating part communicating with the first and second coolant flow paths, a cover (3) which comprises a third coolant flow path (2C) communicating with the thermostat accommodating part and covers the thermostat accommodating part, and a thermostat (10) which comprises a thermoelement (10h) that moves forward and backward according to the change of the temperature of a coolant flowing through the thermostat accommodating part. The thermostat device is provided with a temperature sensor (20) which is provided to face the inside of the thermostat accommodating part and detects the temperature of the coolant. A sensor mounting part (21) which is provided with the temperature sensor therein is provided integrally at the inner end of the cover, and a lead connecting part (25) which is drawn to the outside from the temperature sensor is provided integrally at the outer end of the cover.</p> |
