A vehicle alternator is disclosed as having a stator having a stator winding, a rotor carried on a rotary shaft and rotatably supported inside an inner periphery of the stator, an electric device involving a rectifier for converting an AC voltage, induced in the stator winding, into a DC voltage, and a protector cover for covering the electric device. The protector cover includes a cover body, placed in a position to cover the electric device involving the rectifier, and a cover convex portion extending outward from the cover body along an axis of the rotary shaft of the rotor. The cover convex portion has an inside formed with an open space in which no electric device is disposed.
