Abstract
There is provided a vehicle AC generator in which the contact face of at least one of a pair of cases that make contact with the respective axis-direction end faces of a stator core is provided with a cooling air path that connects the outer circumferential surface of a coil end portion with the outer circumferential surface of the stator core and has an opening in the axis direction at the outer circumferential surface of the stator core so that the coolability of the coil end portions of the stator coil is raised, and the amount of cooling air is increased so that the overall coolability of the AC generator is improved.
