Abstract
Provided is a centrifugal compressor impeller which is characterized in that leading edges 7a on a shroud side of splitter blades 7 are offset from a circumferentially equidistant position between full blades 5R and 5F toward a suction side Sb of the full blade 5F, and trailing edges 7b on a hub side of the splitter blades 7 are offset from a circumferentially equidistant position between the full blades toward the suction side Sb of the full blade 5F, so that a tip leakage vortex W flowing from a tip clearance between the tips of the full blades 5F and the shroud toward the leading edges 7a of the splitter blades 7 flows over the leading edges 7a of the splitter blades 7.
