PURPOSE: A structure for cooling a turbocharger is provided to supply oil to the turbocharger even when an engine is stopped and to prevent the burning of the turbocharger by installing an oil reservoir and an auxiliary oil pump at the upper side and lower side of the turbocharger respectively. CONSTITUTION: An oil reservoir(20) is formed at an oil supply pipe(10) for supplying a turbocharger(1), and stores the oil which cools the turbocharger for a predetermined time when an engine is stopped. A bypass pipe(22) is formed at an oil return pipe(13), and bypasses the oil into an auxiliary oil pump(24). The auxiliary oil pump formed at the bypass pipe inhales the oil from the oil reservoir when the engine is stopped and supplies the oil to the turbocharger. A solenoid valve(26) is formed at the branch of the oil return pipe and bypass pipe, and guides the oil in the oil reservoir to the bypass pipe.
