Abstract

The generator comprises a polyphase stator coil 5 having a lead conductor 19 wound and inserted into a stator core 4, a rotor 6 having rotor cores 8 and 9 for forming magnetic poles, a front bracket 1 and a rear bracket 2 for holding a stator 3 and rotatably supporting the rotor 6, and a commutator 17 which is mounted in this rear bracket 2 and to which a metal terminal 20 bonded to the lead conductor 19 of the stator coil 5 is connected, and it is configured so that bonding between the lead conductor 19 and the metal terminal 20 is fixed by caulking with bonding pieces 20a and 20b provided in the metal terminal 20 embracing the end of the lead conductor 19 from both sides and spacing between the bonding pieces 20a and 20b embracing from both of these sides is bonded and fixed by arc welding.
