There is provided a rotor of a compressor motor at a low cost in which a balance weight is stably positioned. A rotor includes a rotor laminated steel plate (12), rotor end plates (16, 18) arranged on both end surfaces of the rotor laminated steel plate (12), and balance weights (20, 22) provided on the outer surfaces of the rotor end plates (16, 18), respectively. The rotor laminated steel plate (12) and the rotor end plates (16, 18) are provided with at least three axial through holes (24) that are equally spaced apart in the circumferential direction. The rotor laminated steel plate (12) and the rotor end plates (16, 18) are fixed by three rivets (26a, 26b, 26c) passing through the axial through holes (24), respectively. The balance weight (20) is fixed to the rotor end plate (16) by the two rivets (26a, 26b) of the three rivets. The balance weight (22) is fixed to the rotor end plate (18) by the remaining one rivet (26c), and is positioned by the engagement members (28). |
