6 is provided with an oil circulation passage for cooling the cylinder head which is fed under pressure by a pump 13 and then returned to the oil pan 6, and an oil cooler C is provided in a part of this oil circulation passage to receive the cooling air from the cooling fan 7. In a cylinder head oil cooling system of a certain air-cooled engine, at least one of the oil supply path a from the pump 13 to the cylinder head 5 side and the oil return path b from the cylinder head 5 side to the oil pan 6 is connected to the outside of the cylinder 4. 1. A cylinder head oil cooling device for an air-cooled engine, characterized in that the cylinder head oil cooling device is configured in an external pipe line along the outer pipe line, and an oil cooler section C is formed in the external pipe line.
