Abstract

A vehicular rotary electric machine has a stator and a rotor supported by a bracket; a field winding which is provided on the rotor and is for generating a magnetomotive force; a field circuit section which is for supplying a current to the field winding; and a brush holder having a brush, the field circuit section and the brush holder being separately mounted to the bracket. In the vehicular rotary electric machine, connecting means between the field circuit section and the brush holder is configured by an intermediate wiring member having a stress buffering mechanism.

Claims (19)

1. A vehicular rotary electric machine, comprising:

a bracket;

a stator supported by said bracket;

a rotor supported by said bracket;

a power transmission portion provided in front;

a field winding which is provided on said rotor and is for generating a magnetomotive force;

a field circuit section which is mounted to said bracket and is for supplying a current to said field winding; and

a brush holder having a brush, said brush holder being mounted to said bracket separately from said field circuit section, said vehicular rotary electric machine, comprising:

connecting means between said field circuit section and said brush holder, said connecting means being configured by an intermediate wiring member having a stress buffering mechanism.

2. The vehicular rotary electric machine according to claim 1 ,

wherein said intermediate wiring member is composed of a resin planar face portion and a metal wiring material parallel to one face which forms said field circuit section,

said metal wiring material protrudes toward a direction of said brush holder in a normal direction of said planar face portion and is connected to a terminal of said brush holder, and

said intermediate wiring member is mounted to a face on the long-side side that in on the brush holder side of said field circuit section.

3. The vehicular rotary electric machine according to claim 2

wherein at least either one of said field circuit section and said brush holder is mounted to said bracket at least two fixing portions and above disposed parallel to said planar face portion of said intermediate wiring member.

4. The vehicular rotary electric machine according to claim 2

wherein said metal wiring material of said intermediate wiring member is provided with an elastic region.

5. The vehicular rotary electric machine according to claim 2

wherein said planar face portion of said intermediate wiring member becomes a cover of a mounting face of said field circuit section.
