摘要： A vehicular alternating current generator includes a Lundell rotor and a stator. The Lundell rotor includes a cylindrical portion around which a field coil is wound; plate-shaped first and second end plate portions disposed on both end faces in an axial direction of the cylindrical portion so as to face each other; a plurality of first claw portions extending in parallel with a rotational axis in a direction from the first end plate portion to the second end plate portion; and second claw portions extending in parallel with the rotational axis in a direction from the second end plate portion to the first end plate portion, the second claw portions being disposed circumferentially and alternately relative to the first claw portions. The stator is disposed on an outer periphery of the rotor so as to face the rotor with a small rotational air gap there between.
