PROBLEM TO BE SOLVED: To provide a lubricating device for an engine with a turbocharger which prevents a delay in supplying oil to a turbocharger. SOLUTION: An outlet side of a gear pump 17 and a main gallery 20 of an engine are connected by a first pipe line 21. A check valve 30 is integrated in a pipe line C part 21C of the first pipe line 21. During stop of the engine, the main gallery 20 and the turbocharger lubricating pipe line 51 are cut off from the gear pump 17 by the check valve 30 so that leakage of oil to the side of the gear pump 17 can be prevented. During engine operation, hydraulic pressure can be raised immediately after the engine operation, since leakage of oil to the side of the gear pump 17 is prevented during the stop of the engine. Since oil is supplied to the side of the turbocharger 50 through the medium of the turbocharger lubricating pipe line 51 irrelevant to the main gallery 20, delay in supplying oil to the turbocharger 50 can be almost prevented.
