摘要： PROBLEM TO BE SOLVED: To provide a structure which enables a bus bar holder to be positioned in the axial direction and also enables a claw part and a receiving part to be arranged without causing unnecessary stress in the bus bar holder or an insulator even when an axial dimension error occurs in the bus bar holder or the insulator in a motor having a bus bar.SOLUTION: A bus bar holder 232A holding a bus bar 231A has an annular holder body part 60A and a first leg part 61A and a second leg part 62A which extend downward from the holder body part. The first leg part 61A has a claw part 611A protruding in the lateral direction. An upper surface of the claw part 611A faces a lower surface of a receiving part 521A provided at an insulator in the axial direction through a gap. Thus, the bus holder 232A is restricted from moving upward by the claw part 611A and the receiving part 521A of the insulator. On the other hand, a lower end part of the second leg part 62A is in contact with a teeth 512A or the insulator 52A.

摘要： PROBLEM TO BE SOLVED: To provide a technique that improves strength with which a rotor core and a holder are fixed to each other, in a rotor unit for a rotary electric machine.SOLUTION: A rotor unit 32A has a resin holder 42A, and a rotor core 41A that includes vertically laminated steel sheets. The rotor core 41A and the holder 42A are fixed to each other by insert molding. Thus, a manufacturing process of the rotor core 41A and the holder 42A is shortened. On an outer circumferential surface of the rotor core 41A, furthermore, part of the resin that forms the holder 42A is interposed among the steel sheets that form the rotor core 41A. Thus, the rotor core 41A and the holder 42A are fixed to each other with improved strength. Since the rotor core 41A and the holder 42A are prevented from being separated from each other, moreover, magnets 43A are easily pressed into place.
