摘要	At least three axis direction through-holes arranged at equal intervals in the circumferential direction are provided in a rotor laminated steel plate and a rotor end plate. The rotor laminated steel plate and the rotor end plate are fixed with three rivets for passing through the axis direction through-holes. A balance weight formed of one laminated metal plate is fixed to the one rotor end plate with two rivets of the three rivets. A balance weight formed of the other laminated metal plate is integrated by caulking and has a projection formed thereon and fixed to the other rotor end plate with the remaining single rivet. The projection is engaged with a recess or a through-hole provided in the other rotor end plate so that the balance weight is positioned to the other rotor end plate.
