PROBLEM TO BE SOLVED: To suppress the occurrence of defective goods by preventing the deformation and the shift of a terminal at resin molding. SOLUTION: A field coil 2, which generates magnetic field, is wound on an insulating bobbin 5. It has a first pole core body 3 and a second pole core body 4 which are provided to cover this field coil 2 so that they may engage with each other. It is provided with a plurality of slip rings 14a-14d which supply the field coil 2 with field currents via a brush from outside a rotor and terminals 8 and 9 which connect each slip ring 14a-14d with the field coil 2. The terminals 8 and 9 consist of axial extensions 8a and 9a which extend axially and diametrical extensions 8b and 9b which extend diametrically. In the axial extensions 8a and 9a, ribs 15 for raising flexural rigidity are made in parallel with a rotating shaft. COPYRIGHT: (C)2009,JPO&INPIT
