摘要： A hybrid drive device includes a first transmitting shaft coupled to an output shaft of an engine and a second transmitting shaft coupled to a rotor of a rotary electric machine and a transmission, the first transmitting shaft is supported in a radial direction between a first end portion on the engine side and a second end portion on the transmission side in an axial direction by a case via a first radial bearing, the second end portion of the first transmitting shaft is inserted into an end portion on the engine side of the second transmitting shaft formed in a tubular shape, a second radial bearing that supports the second transmitting shaft in the radial direction is disposed between an outer peripheral surface of the second end portion of the first transmitting shaft and an inner peripheral surface of the end portion of the second transmitting shaft, and the second transmitting shaft is supported in the radial direction by a shaft support portion provided in the case on the transmission side of the end portion via a third radial bearing. Thus, it is possible to shorten the axial length of the hybrid drive device while suppressing a shaft runout of a transmitting shaft that coupled the rotor of the rotary electric machine and the transmission.

摘要： To achieve a manufacturing method for a rotary electric machine rotor that can reduce deviation of a radial load that interacts on a rotor core and a tubular portion among axial positions.
MEANS OF SOLVING THE PROBLEM
A rotary electric machine rotor 1 includes a rotor core 2 and a core support member 3 that supports the rotor core 2. The core support member 3 includes a tubular portion 11 formed in a tubular shape and a support portion 12 supported so as to be rotatable with respect to a non-rotary member to support the tubular portion 11 from the inner side in a radial direction R. The core support member 3 is formed such that a diameter D1 of a fitting surface portion A2 in a specific region A4, which includes an overlapping region A3 which overlaps a connection region A1 as viewed in the radial direction, is smaller than a diameter D2 of the fitting surface portion A2 in a general region A5 which is a region other than the specific region A4. The manufacturing method includes: inserting the core support member 3 to the inner side in the radial direction R with respect to the rotor core 2 with the rotor core 2 expanded; and thereafter shrinking the rotor core 2 relative to the tubular portion 11 to fit an outer peripheral surface F1 of the tubular portion 11 and an inner peripheral surface F2 of the rotor core 2 with each other.
