PROBLEM TO BE SOLVED: To provide a lubrication oil supply mechanism for a turbocharger which allows the size of the turbocharger to be reduced.SOLUTION: A lubrication oil supply mechanism for a turbocharger 5 includes a supply oil passage 42 which directs lubrication oil, pumped out from an oil pump, to a bearing part 41 of a bearing housing 40 rotatably supporting a shaft 10 connecting a compressor wheel and a turbine wheel; and a flow control valve 50 which is provided in the supply oil passage 42 and adjusts the flow rate of the lubrication oil by varying an opening area of a flow channel for the lubrication oil on the basis of the pressure of the lubrication oil flowing in the supply oil passage 42. The flow control valve 50 is integrally formed with the bearing housing 40, and includes a valve body 110 through the inside of which the lubrication oil can flow, and a spool 120 which slides inside the valve body 110 to vary the opening area. |
