PROBLEM TO BE SOLVED: To provide a lubricating structure of a turbocharger superior in durability, while reducing a driving energy loss of an oil circulating pump. SOLUTION: This lubricating structure has an oil level sensor 31 for detecting an oil level in oil collecting tanks 27L and 27R for recovering oil discharged from the turbochargers 10L and 10R by lubricating the turbochargers 10L and 10R by the oil supplied from an oil pan 25; and sends out the oil in the oil collecting tanks 27L and 27R to the oil pan 25 by oil recirculating pumps 28L and 28R by rotational driving of electric motors when an oil volume sensor 31 detects a preset oil level position L1 or more. The rotational driving of the electric motors 28Lm and 28Rm is controlled in response to the oil volume of oil stored in the oil collecting tanks 27L and 27R, and the energy loss can be largely reduced by largely restraining electric power consumption, and the superior durability can be secured.
