PROBLEM TO BE SOLVED: To provide a bus ring unit which can achieve downsizing in an axial direction and a radial direction.SOLUTION: A single phase bus ring has: single phase side arc areas which are arranged along a circumferential direction so as to be positioned on a circle having a diameter smaller than that of a neutral point bus ring and serially disposed in the circumferential direction so as to sandwich gaps, each single phase side arc area including circumferential edges which are displaced from a neutral point side connection area of the neutral point bus ring with respect to the circumferential direction and are positioned at a second axial position displaced from a first axial position, in which at least a part of the neutral point bus ring is positioned, with respect to an axial direction; and a pair of sing phase side extension pieces which extend from facing edges of the adjacent single phase side arc areas to the radial outer sides, get beyond a portion of the neutral point side arc area of the neutral point bus ring which is positioned in the first axial position to extend in the radial outer side, and are connected at tip parts.SELECTED DRAWING: Figure 1 |
