動シャフトとの連結構造。A ceramic turbine wheel comprising a rotor blade section that receives the pressure of exhaust gas discharged from an internal combustion engine, and a rod-shaped attachment section protruding from the center of the back surface of the rotor blade section;
and a drive shaft for transmitting the rotation of the turbine wheel to the compressor wheel, a fitting part is provided at the tip of the drive shaft, and a fitting part is provided at the center of the end surface of the fitting part, and a part extending in the axial direction is provided at the center of the end surface of the fitting part. A fitting hole is bored, and the mounting part is press-fitted into the fitting hole to connect the turbine wheel and the drive shaft, and the mounting part is press-fitted into the fitting hole to connect the turbine wheel and the drive shaft. The distal end portion of the fitting portion applies a compressive force to the mounting portion, and the other portion of the fitting portion reduces pressure to at least one of the mounting portions. A connection structure between a turbine wheel and a drive shaft of a turbocharger, characterized in that a means is provided.
