Claims

[Scope of utility model registration request]

A turbo supercharger comprising an exhaust gas turbine driven by engine exhaust gas, a compressor driven by the exhaust gas turbine, and a bearing disposed between the exhaust gas turbine and the compressor. A waste gate valve is provided in the casing of the exhaust gas turbine and communicates the exhaust gas inlet with the exhaust gas outlet by opening the waste gate valve, and the waste gate valve responds to the pressure of lubricating oil supplied to the bearing part. 1. A lubrication device for a turbocharger, characterized in that the lubrication device is connected to an actuator for controlling a turbocharger, and is configured to be opened by the actuator when lubricating oil pressure is lower than a set value.
