The opposite end flanges 1d, 1e of a stator bobbin are provided with apertures 1a, 1b and clamping recesses 1c to firmly retain push-inserted terminal plates 3 and lead wires 4 during encapsulation by a molding resin 5. The retention of the terminal plate ends is implemented by spring flukes 3c snapping into engagement with flange apertures 1b during insertion.
