PROBLEM TO BE SOLVED: To provide an engine cooling device capable of accurately controlling flow rate of refrigerant with a simple structure in a plurality of terminal devices exchanging heat with using refrigerant circulated for cooling an engine. SOLUTION: The engine cooling device including the plurality of terminal devices exchanging heat with using refrigerant circulated via a radiator cooling the engine 6 and provided with a first circulation channel R10 passing through the radiator 5 and a second circulation channel R20 passing through the terminal devices includes a structure described below. The second circulation channel R20 includes a first terminal channel R1 passing through a first terminal device 1 making refrigerant absorb heat and a second terminal channel R2 passing through a second terminal device 2 connected in parallel with the first terminal channel R1 and making refrigerant radiate heat. The first terminal channel R1 is provided with a mechanical control valve 3 opening large in case that temperature of refrigerant is high and opening small in case that temperature of refrigerant is low in a downstream of the first terminal device.
