PROBLEM TO BE SOLVED: To obtain a rotor for a compressor motor that can stably be positioned by integrating individual balance weight plates.SOLUTION: At least three axial through-holes circumferentially arranged at equal intervals are provided in a rotor layer-steel-plate and rotor end-plate. The rotor layer-steel-plate and the rotor end-plate are fixed by three rivets passed through the axial through-holes. A balance weight composed of a layer-metal-plate on one side is fixed to the rotor end-plate on the one side by the two of the three rivets. The balance weight composed of the layer-metal-plate on the other side has a projecting part by being integrated by caulking, and is fixed to the rotor end-plate on the other side by the remaining one rivet. The projecting part fits in a recessed part or through holes in the rotor end-plate on the other side and is positioned with respect to the rotor end-plate on the other side. |
