Abstract
A forced induction device () includes: a rotor () which includes a turbine side shaft portion (), a compressor side shaft portion (), and a connection shaft portion () connecting these to each other; a turbine side bearing () which supports the turbine side shaft portion (); and a compressor side bearing () which supports the compressor side shaft portion (). A rigidity of the connection shaft portion () is lower than that of the turbine side shaft portion () and the compressor side shaft portion () so that a node in a mode shape at each critical speed involving with an operating rotational speed region of the rotor () is located between the turbine side bearing () and the compressor side bearing ().
