Abstract
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.
