According to the invention, in a rotor of a vehicular alternating current generator motor having a Lundell type core having a field winding, a cylindrical portion wound with the field winding, a yoke portion widened from a portion in an axial direction of the cylindrical portion in an outer peripheral direction, and a plurality of claw-like magnetic pole portions constituted to incorporate the field winding, extended in the axial direction from an outer periphery of the yoke portion and folded to bend to be brought in mesh with each other alternately, and a magnet arranged between the claw-like magnetic poles, an outer peripheral face of the field winding and an inner peripheral face of the magnet are made to be proximate to each other to thereby hamper draft between the field winding and the magnet.
