Zusammenfassung:	It relates to a rotor provided in a vehicular AC generator that is provided as a rotating electric machine in a vehicle or the like and that is driven by an engine of the vehicle to generate power, and relates to a bobbin structure on which a field coil provided in a rotor is wound. A detachment prevention portion extending in a circumferential direction of a flange portion of a bobbin from a neck portion of a locking portion provided so as to extend radially outward from the flange portion is formed such that a length by which the detachment prevention portion extends to one side in the circumferential direction is longer than a length by which the detachment prevention portion extends to another side in the circumferential direction. Accordingly, interference between cover portions and a field coil winding or between the cover portions and a winding jig for the winding during operation of winding a lead wire of the winding can be inhibited while electric insulation between a field coil and claw-shaped magnetic poles is ensured.
