PCT No. PCT/JP80/00091 Sec. 371 Date Nov. 5, 1980 Sec. 102(e) Date Nov. 5, 1980 PCT Filed Apr. 30, 1980 PCT Pub. No. WO80/02481 PCT Pub. Date Nov. 13, 1980.The present invention relates to a method of connecting an armature coil with a commutator segment which includes connecting the end portion of an armature coil by ultrasonic welding to the commutator segment which is arranged in the same direction as the axis of a shaft and is initially formed with a molded substrate, wherein said ultrasonic welding is performed while the commutator segment is fixed in place by a rigid pressing member. The present invention is suitable for connecting the armature coil of a rotary machine such as the starter motor to a commutator segment.
