摘要： A cooling structure for a rotating electrical machine includes a rotating electrical machine including a stator and the stator, a temperature sensor, and a first discharge mechanism. A plurality of discharge holes of the first discharge mechanism is disposed in a region excluding an avoidance region. The avoidance region is the same region as an arrangement region that is one of a right side region and a left side region with respect to a vertical line passing an axis of the stator as seen in the axial direction of the stator core, the one of the right side region and the left side region being a region in which the temperature sensor is arranged and the avoidance region is located above a lower end of the temperature sensor in the gravitation direction.

摘要： A connection device includes a connector provided with wire insertion holes receiving end portions of electrical wires and terminal fittings connected to the end portions. The electrical wires include a lead wire and a dummy wire. One end of the lead wire is inserted in the wire insertion holes while another end of the lead wire is connected to another connector. One end and another end of the dummy wire are inserted in empty ones of the wire insertion holes. A protective tube, which is shorter than the lead wire, is provided between the connector and the other connector, so as to extend over an entire length of the lead wire except opposite end portions of the lead wire and so as to cover the lead wire and the dummy wire. A U-shaped curved end portion of the dummy wire is exposed from an end portion of the protective tube.

摘要： A rotor core includes a shaft hole, into which a shaft is inserted, and keys, which are protrusions corresponding to keyways of the shaft. A radial distance, which is the distance from the center of the shaft hole to an inner wall varies depending on the position in the circumferential direction of the shaft hole. The shaft hole includes key regions and increased diameter regions, in each of which the radial distance is longer than the radius of the shaft. Keys are respectively arranged in the key region. The shaft hole also includes contact regions, in which the shaft and the inner wall come into contact with each other when the shaft is inserted into the shaft hole. The contact regions are each located between the key regions or between the increased diameter regions. The contact regions are arranged at equal intervals in the circumferential direction.
