Abstract:
An electricity collection and distribution ring includes a plurality of bus rings that include a plurality of annular conductive bodies and a plurality of connecting terminals provided on the annular conductive bodies. The connecting terminals each include a first connecting portion connected to a center conductor, a second connecting portion connected to a winding and a coupling portion for coupling the first and second connecting portions. The coupling portion includes the first extended portion including an end portion extending through a gap between the annular conductive bodies toward one side in an axial direction of the annular conductive bodies and the second extended portion extending from the end portion of the first extended portion toward one side in a radial direction of the annular conductive bodies. The second connecting portion is formed at an end portion of the second extended portion on one side in the radial direction.
