Abstract
It is configured in such a manner that a convex portion (15a) provided to an inner surface of a cover (15) protecting a rectifier device (13) and a voltage regulator (14) as components forming a vehicle AC alternator is fit in a concave portion (13a) provided to a component opposing the inner surface of the cover in close proximity and that the fitting configuration is provided to a point-symmetric position with respect to an external connection terminal (Tb or 12) of the components protruding from inside to outside of the cover.
Claims8
An alternator for vehicle comprising a case supporting components, a rotor supported on the case in a rotatable manner, a stator located on an outer periphery of the rotor and supported on both sides by the case, a stator winding provided to the stator, a rectifier device rectifying an AC electromotive force generated in the stator winding to a DC, and a voltage regulator limiting an alternator power to a specified value, in which at least one of the rectifier device and the voltage regulator, which are the components, is supported on the case on an opposite side to the rotor and
- its outer periphery is protected by a cover, characterized in that:
- a convex portion provided to an inner surface of the cover is fit in a concave portion provided to the components at a region opposing the inner surface of the cover in close proximity in a fitting configuration, the convex portion directly contacting the concave portion;
- and
- the fitting configuration is provided to at least a point-symmetric position with respect to an external connection terminal of the components protruding from inside to outside of the cover.
