In the oil cooler module 31, an introducing pipe 34 and a drain pipe 35 for circulating cooling water to the oil cooler and a bypass pipe 36 for allowing the cooling water to bypass are formed integrally with an oil cooler main body 32. A thermostat 29 for switching the circulation of the cooling water to the oil cooler and the bypass of the cooling water to the bypass pipe 36 is inserted from the drain pipe 35 and attached. The thermostat 29 allows the cooling water to bypass the oil cooler when the temperature of the cooling water is lower than a prescribed temperature and to circulate to the oil cooler when the temperature of the cooling water is the prescribed temperature or higher.
