発明は上記課題を解決するために次の構成をとる。Since the conventional radiator for cooling the engine and the heat exchanger for air conditioning are manufactured separately and independently, there is a disadvantage that the number of parts is large and the assembly is troublesome. An oil cooler is provided inside the engine cooling radiator. This oil cooler was also produced separately and independently, was installed in a radiator tank, and was connected to the oil cooler by inserting an oil pipe through a through hole on the side surface of the tank. For this reason, the number of parts is further increased, and the assembly is troublesome and there are many seal portions. Furthermore, the work of installing an oil cooler in a relatively small radiator tank is troublesome, and there is a drawback that the workability is lacking. Therefore, the present invention employs the following configuration in order to solve the above problem.
