Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a cooling device of a turbocharger that can suppress a decrease of turbo-charging efficiency of the turbocharger when an engine is cooled down.SOLUTION: The device includes an exhaust gas cooling adapter 50 for exchanging heat between exhaust gas and a coolant, a turbocharger 60 formed with an in-housing water jacket 61a, a coolant passage 80 for supplying the coolant having been supplied to the adapter 50 to the in-housing water jacket 61a, and a control valve 70 for adjusting a flow rate in the coolant passage 80. When the engine is cooled down, a control device 90 controls an opening of the control valve 70 so that the flow rate in the coolant passage 80 decreases compared to when the engine is warmed up.
