Reductions in cost and manufacturing processes are achieved by interposing a single metallic terminal between a lead wire of a stator and a three-phase output terminal. A rotor 3 is fixed onto a rotating shaft 2 disposed rotatably in a housing 1, and a stator core 5 is disposed opposite to the rotor 3. A stator winding 6 is wound around the stator core 5 and a lead wire 10 of the stator winding 6 is connected to a head portion 8a of a three-phase output terminal 8 through a single metallic terminal by a screw 12.

DETAILED DESCRIPTION The present invention has been made to solve the above-discussed problems and has an object of reducing not only cost and manufacturing processes but also resistance of the metallic terminal in order to improve output and efficiency by interposing just a single metallic terminal between a lead wire of a stator and a three-phase output terminal.
An electric rotating machine for vehicle of the invention includes a rotor fixed onto a rotating shaft disposed in a housing, a stator core disposed opposite to the rotor, a stator winding wound around the stator core, and a three-phase output terminal to which a lead wire of the stator winding is connected.
And the lead wire is connected to the three-phase output terminal through a single metallic terminal.
As a result, not only cost and manufacturing processes but also resistance is reduced, and therefore output and efficiency are improved.
