Claims

[Scope of utility model registration request]

In a compressor impeller that is fitted onto a rotating shaft and fastened with its back surface in contact with a contact surface of a positioning member provided on the rotating shaft, at least the contact surface of the positioning member and the back surface of the compressor impeller are connected. A compressor impeller characterized in that both of the compressor impeller are formed with a vertical surface perpendicular to the rotational shaft and a cone-shaped tapered surface adjacent to the vertical surface and inclined toward the rotational shaft.
