PROBLEM TO BE SOLVED: To provide a compressor wheel assembly for economically machining a sufficiently narrow hole in a compressor wheel with accuracy of a required degree. SOLUTION: This compressor wheel assembly has the compressor wheel 7 installed on a rotary shaft 8. This shaft 8 extends by penetrating through the hole arranged along the rotary shaft of the wheel. The hole has an inner diameter larger than an outer diameter of the shaft 8. A cylindrical sleeve 22 is coaxially arranged around the shaft 8, and thus, the shaft 8 is coaxially held inside the hole.
