Disclosed is an impeller (54) of a centrifugal blower for a vacuum cleaner in which caulking positions (R1 to R4) of each blade (54c) caulked between front and rear covers (54a,54b) are set, taking into consideration design parameters including the length and maximum camber position (MCP) of the blade, so as to disperse the stress concentrated on each caulked portion of the blade (54c), thereby causing a minimum stress to be applied to the caulked portion of the blade (54c), so that the impeller (54) secures a structural stability. <IMAGE> |
