PROBLEM TO BE SOLVED: To provide a thermostat capable of actively controlling temperature of cool water by converting flow paths of cool water according to the temperature of cool water circulating to prevent overheating.SOLUTION: A thermostat includes: a first valve 200 opening and closing a first flow path 155; a second valve 205 opening and closing a second flow path 165 at the other side; a valve body 125 connecting the first valve and the second valve integrally; a main spring 145 elastically supporting the valve body in the direction of the first flow path to allow the first valve to close the first flow path and the second valve to open the second flow path; and a driving part, pushing the valve body in the direction where the second flow path is formed, allowing the first valve to open the first flow path and the second valve to change the degree of opening of the second flow path. |
