A highly reliable connection structure of a bundle of more than two coil leading-out wires and a wire bundling terminal is provided by contacting and fixing at least a part of a circumferential surface of each of the coil leading-out wires to an inside wall of the wire bundling terminal. Further, a small size motor and an alternator for a vehicle utilize the connection structure.

A method and apparatus for treatment of stator coil lead wires for an electric rotary machine, in which a plurality of coil lead wires extending in the radial direction of a stator for an electric rotary machine are movably arranged between two plane-like or cylindrical-surface members opposite to each other; the plurality of coil lead wires are pressed in a predetermined gathering direction by a lead wire pressing member which is capable of moving between the two plane-like or cylindrical-surface members, so that the plurality of coil lead wires are transformed and gathered into a predetermined shape. Thus, the coil length required for treatment of the stator coil lead wires can be reduced, and the lead wire treatment can be performed quickly and automatically.
