Patent ID: 8067866

Claim:
A central electricity distribution member for a rotary electric machine, comprising: connecting bus bars of respective phases for connecting, among coils of respective phases wound around a stator of the rotary electric machine, the coils of the same phases; a bus bar for a neutral point for connecting the coils of the same phases wound around the stator of the rotary electric machine; a bus bar insulating portion having a circular holding groove for accepting a respective bus bar and insulating the respective bus bars from one another; an insulation-side positioning portion provided on the bus bar insulating portion; and a bus bar-side positioning portion provided on each of the bus bars, for performing positioning between the bus bar insulating portion and the respective bus bars in cooperation with the insulation-side positioning portion, wherein the insulation-side positioning portion is one of inside walls opposed to a groove width direction of the holding groove, the one inside wall having at least a lower part thereof, that is proximate a bottom surface of the holding groove, inclined such that the groove width of the holding groove becomes smaller from an opening side to the bottom surface of the holding groove, and the bus bar-side positioning portion is a curved portion for abutting on the inclined wall, and wherein the bus bar-side positioning portion is slidably engageable with a face of the lower part of the inclined inside wall so that the bus bar-side positioning portion moves in the width direction across the holding groove as it slides toward the bottom surface of the holding groove.
