PURPOSE: A device for lubrication and cooling of a turbo charger is provided to prevent the burning of a bearing unit by lubricating and cooling the bearing unit with engine oil even when an engine is stopped. CONSTITUTION: An auxiliary lubrication supply pipe(13) is branched from a lubrication supply pipe(10). An oil reservoir tank(14) is connected to the auxiliary lubrication supply pipe. A piston ram(15) is received in the oil tank to be lifted up by the oil in the tank. The piston ram is supported on a return spring(16) rebounding against the oil pressure. When an engine is stopped suddenly, the supply of engine oil to a bearing case(7) is stopped. Then, the piston ram slides down by the rebounding force of the return spring and pushes the engine oil in the oil reservoir tank out. Then, the engine oil is supplied to the bearing case through the auxiliary lubrication supply pipe. Therefore, the overheating of a turbo charger(1) is prevented.
