ABSTRACT:
A stator of an AC generator according to the present invention has a stator core which is formed in a ring shape having tooth portions protecting inside said ring shape and forming slots. The width of the slot formed in a stator core is designed in such a manner that, with respect to the depth direction thereof, each inner half section of the slot is a tapered shape having a larger bottom width, and each outer half section of the opening-side of the slot has a constant width between parallel edges, so as to allow a stator coil to be inserted easily between the tooth portions.
