PROBLEM TO BE SOLVED: To reduce the manufacturing cost of bus bars used for a stator in a dynamo-electric machine of a hybrid vehicle and a fuel cell vehicle or the like. SOLUTION: In a unit for combining the bus bars used for the stator in the dynamo-electric machine, coils are wound onto respective annularly disposed teeth and connected by linear bus bars 3(3a, 3b, 3c) annularly arranged for each phase of respective coils. Insulative holders 11 of the bus bars are provided in regions for connecting coils, maintain gaps between the bus bars, and ensure insulation properties. If the holder is divided, the cost of the holder can be reduced. If the bus bar is formed from a linear material, the cost of the bus bar can be reduced. Accordingly, the cost of the unit for combining the bus bars can be reduced. COPYRIGHT: (C)2007,JPO&INPIT
