PROBLEM TO BE SOLVED: To provide a compressor impeller assembly endurable against high speed rotation even in a rotary shaft having a small diameter by preventing a rotational directional slip to the rotary shaft of a compressor impeller with a simple constitution. SOLUTION: This compressor impeller assembly has the compressor impeller 7. This compressor impeller 7 is installed on the rotary shaft 8 extending by passing through a through-hole arranged along the central shaft. The compressor impeller 7 is fixed to the rotary shaft 3 by a key so that rotation of the rotary shaft 8 rotates the compressor impeller via key fitting. COPYRIGHT: (C)2004,JPO
