Abstract
A turbocharger includes a turbine wheel, a turbine housing, a bearing housing, a compressor housing, a seal plate, a variable nozzle mechanism, a penetrating shaft, and a spring member. The variable nozzle mechanism is located within the turbine housing, and adjusts the amount of exhaust gas that flows toward the turbine wheel. The penetrating shaft extends through the bearing housing and is connected to the variable nozzle mechanism. The spring member pushes out the penetrating shaft toward the compressor housing. The bearing housing and the seal plate define a cooling chamber through which coolant flows. The spring member is located in the cooling chamber.
