Abstract: The exhaust turbocharger comprises a turbine having a turbine wheel and a compressor having a compressor wheel. The turbine wheel and the compressor wheel are connected by a shaft rotatably mounted in a bearing housing. A means for axially securing the shaft and the turbine wheel connected thereto is provided between the compressor wheel and the turbine wheel, wherein this means for axial securing limits an axial movement of the shaft and of the turbine wheel connected thereto in the direction of the turbine in the event of the compressor wheel bursting.The means for axially securing the shaft and the turbine wheel connected thereto comprises a component which is connected to the shaft or mounted on the shaft and is fixed in the axial direction in the housing. According to the application, this component for axially securing is screwed onto the shaft during mounting.
