PURPOSE:To enhance reliability of securing an auxiliary pole to a yoke by weld bonding the pole. CONSTITUTION:A pole 3 and an auxiliary pole 4 are bonded to the inner periphery of a yoke 2. The pole 4 and the yoke 2 are electric resistance welded by using the pole 6 of an electric resistance welding machine. The pole 4 and the yoke 2 may be welded by using other welding process such as an electron beam welding, a plasma arc welding or a gas welding instead of the electric resistance welding.
