Claims

[Scope of utility model registration request]

The torque of the rotor shaft, which is integrated with the turbine blade, is transmitted to the sleeve through the engagement between the spline shaft and the spline hole, and the rotation of the sleeve is transmitted to the compressor blade through the engagement between the claws on the end surface of the compressor impeller and the grooves in the sleeve. In the connection structure of the rotor shaft that is transmitted to the vehicle, bending of the rotor shaft is prevented by forming the same simultaneous processing surface on the pawl portion of the compressor wheel and bringing the same simultaneous processing surface into close contact with the end surface of the sleeve. A rotor shaft connection structure characterized by:
