ENGINE COOLING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an engine cooling device capable of increasing motor driving efficiency and reducing the rotation noise of a cooling fan when the rotation of the cooling fan is not required. SOLUTION: This cooling fan 57 is connected to one end 56a of the rotating shaft 56 of a motor 55 via a one-way clutch 70. Only when the motor 55 is reversely rotated when cooling an engine, the rotation of the motor 55 is transmitted to the cooing fan 57 via the one-way clutch 70.
