のロータシャフト冷却装置。A center housing body is formed with an oil intake port that receives lubricating oil pumped from the engine and an oil return port that returns the lubricated oil to the engine; The inner cavity of the center housing body is connected to an oil upper chamber and an oil chamber. a rotor shaft housing, which is divided into two parts and formed so that the rotor shaft is loosely fitted through the bearing; a hole is formed in the rotor shaft housing so that oil is supplied to the bearing from the oil upper chamber side of the rotor shaft housing; an oil supply port formed in the rotor shaft housing to discharge oil supplied to the bearing to the oil lower chamber side of the rotor shaft housing; and a rotor shaft loosely fitted in the bearing. A rotor shaft cooling device for a turbocharger, characterized in that an oil spray port is formed separately from the oil supply port on the oil upper chamber side of the rotor shaft housing so as to directly supply oil to the rotor shaft housing.
