A rotator of a rotating electric machine that is constructed by press-fitting a shaft (2) into a penetration hole created in a laminated core (3), wherein protruded strip sections (2a) for engaging with the inner wall of the penetration hole are formed on the outer circumferential surface of the shaft (2), the laminated core (3) is segmented into stacked core sections (3b, 3c) having predetermined distances in the axial direction, and relief grooves (3a), which do not engage with the protruded strip sections (2a), are formed in the circumferential direction on the inner walls of the respective stacked core sections (3b, 3c). |
