An alternator for a vehicle includes a stator, a rotor and a pair of cooling fans fixed on opposite sides of the rotor. The stator winding is composed of a conductor group disposed in the stator core and a pair of annular coil-end groups extending from the conductor group to be disposed on opposite sides of said stator core. Each of the coil-end groups has a plurality of coil ends which has a pair of inclined portion, and each one of the inclined portion disposed at the outermost circumference of the coil-end groups inclines to guide the cooling air spirally in an axial direction.
