Abstract: 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.

Abstract: There is provided an electric dust collection device which can effectively capture fine particles while avoiding a pressure loss. The electric dust collection device is provided with a charging electrode, a dust collection electrode, and a repulsive electrode. Along a flowing direction of an airflow, the dust collection electrode is disposed downstream of the charging electrode, and the repulsive electrode is disposed downstream of the dust collection electrode. The dust collection electrode is formed of a conductive material which partitions a ventilation passage through the airflow pass in the flowing direction. The repulsive electrode forms an electric barrier which has the same polarity as that of the charging electrode with a posture that intersects the airflow in the flowing direction.
