Abstract
The object of the present invention is to obtain a thermostat device capable of improving the workability and assemblability, reducing costs, and downsizing the entire device with a minimum number of components. This thermostat device has a first valve discfor opening and closing a first fluid passage, and a second valve discfor opening and closing a second fluid passage, and constituted so as to open either the first fluid channel or second fluid channel and close the other by making the valve discs move integrally in conjunction with the operation of an operating memberin accordance with the temperature change of the fluid. The operating member has a casewhich seals in one end side thereof a thermal expansion bodyhaving a property of expanding and contracting in accordance with a temperature change, and retains a pistonfrom the opening of the other end side thereof in a freely reciprocable manner. The outward flange unitprovided to the opening on the other end side of the case is made to be the first valve disc.
