Abstract

A hybrid exhaust gas turbocharger is provided, which is capable of preventing the supercharger from being damaged due to a rotary shaft being moved to a large extent in an axial direction by vibration generated from the internal combustion engine and a rotary portion in contact with a stationary portion in the supercharger when the supercharger is mounted on an internal combustion engine. A restraint mechanism () including a thrust collar () attached to a shaft end of a rotary shaft () of a generator positioned on a side opposite to a flexible coupling and two thrust bearings () disposed to oppose both end surfaces forming a flange portion () of the thrust collar () is accommodated in a recess () formed on a front surface side of a shell housing positioned on a side opposite to the casing.
