Abstract
Official abstract text for this publication.
The present invention provides an automotive rotary electric machine that can suppress unnecessary disengagement of a protective cover by increasing supporting strength for the protective cover. The automotive rotary electric machine according to the present invention includes: a rectifier and a voltage regulator that are disposed outside a first axial end of a casing; and a resin protective cover that is formed so as to have a cup shape that is constituted by a bottom portion and a cylindrical peripheral wall portion, and that is mounted onto a casing so as to cover the rectifier and the voltage regulator. The protective cover is held by a circuit board of the rectifier by coupling by snap-fitting a plurality of projections that are disposed so as to protrude from an inner circumferential wall surface of the peripheral wall portion to a plurality of projection-engaging portions that are formed on an outer peripheral wall surface of the circuit board so as to be separated circumferentially.
First claim
Opening claim text (preview).
The invention claimed is: 1. An automotive rotary electric machine comprising: a rotor that is disposed inside a casing so as to be fixed to a shaft that is rotatably supported by said casing; a stator comprising: a stator core; and a stator winding that is mounted onto said stator core, said stator being supported by said casing so as to surround said rotor; a rectifier that rectifies alternating-current electric power that is generated by said stator winding, said rect…
