The lubricating oil that has absorbed the heat generated by the fluid coupling 5 and has warmed up is sent from the oil pump 3 to the radiator 1. The radiator 1 efficiently exchanges heat with the cool air sent from the cooling fan 2 to lower the temperature of the lubricating oil. The cooled lubricating oil is returned to the fluid coupling 5 through the oil filter 4.
