Abstract: A brushless alternator for a vehicle comprising a field coil holding device formed by mounting a field coil winding spool directly on a field core using a bonding agent thus eliminating the need for a metallic cylindrical spool holder which requires precise machining in order to engage with the field core for welding. With this arrangement, a simple and inexpensive field coil holding device eliminates former precise machining. In addition, a field coil can be wound around the field coil winding spool in advance, before bonding to the field core.

Abstract: A noise-proof capacitor unit for a vehicular generator comprising an insulator (15) disposed between a positive-side heat sink (13) and a negative-side heat sink (14) of a rectifier for supporting them in an electrically insulating relationship from each other. The insulator (15) has integrally formed therein an insulating receptacle (17) for receiving and supporting therein a capacitor element (11). The capacitor unit also comprises a pair of terminal plates (21, 22) each mounted on the insulator (15) and having one end in electrical contact with the heat sink (13 or 14) and the other end connected to the terminal wire (12a or 12b) of the capacitor element.
