    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.

    摘要: A powertrain unit (10) includes an engine (20) and a power transmission device that transmits drive force of the engine to a drive wheel, the power transmission device including a transmission (36) provided in a power transmission path between the engine and the drive wheel (39T). An oil pan (35D) is provided below the transmission. A guard member (40) covering at least a portion of the oil pan from below is provided below the oil pan. The guard member (40) has one end secured to a portion of the powertrain unit which is located in front of the transmission (36) in a vehicle longitudinal direction, and has the other end secured to a portion of the powertrain unit which is located behind the transmission (36) in the same direction. The rigidity of the powertrain unit can be improved by utilizing the rigidity of the guard member (40).
