摘要： A rotary electric machine rotor includes a rotor core and a core support member that supports the rotor core. The core support member includes a tubular portion formed in a tubular shape and a support portion supported so as to be rotatable with respect to a non-rotary member to support the tubular portion from the inner side in a radial direction. The core support member is formed such that a diameter of a fitting surface portion in a specific region, which includes an overlapping region which overlaps a connection region as viewed in the radial direction, is smaller than a diameter of the fitting surface portion in a general region which is a region other than the specific region.

摘要： A hybrid drive device includes: a rotor; a transmission; and a case, in which a rotor support member that supports a rotor of the rotary electric machine includes an annular member that faces an end wall portion of the case, the end wall portion includes a first tubular portion that protrudes in an axial direction from an inner periphery toward the transmission, and a second tubular portion that protrudes in the axial direction toward the transmission so as to surround the first tubular portion, the annular member includes a tubular portion that protrudes in the axial direction from an inner periphery toward an engine, an inner side radial bearing is disposed between the first transmitting shaft and an inner peripheral surface of the first tubular portion of the end wall portion, a clearance is formed between an outer peripheral surface of the first tubular portion of the end wall portion and an inner peripheral surface of the tubular portion of the annular member, and an outer side radial bearing is disposed between an outer peripheral surface of the tubular portion of the annular member and an inner peripheral surface of the second tubular portion of the end wall portion. As a result, the durability of the bearing for supporting the rotor of the rotary electric machine in the radial direction can be further improved.

摘要： A vehicle drive apparatus includes: a first bearing disposed between a rotor support member and a case in a radial direction so as to restrict movement of the rotor support member to a first axial side relative to the case; and a second bearing disposed between a connecting shaft and the case in an axial direction so as to restrict movement of the connecting shaft to a second axial side relative to the case. A fluid transmission device is disposed on the first axial side relative to the connecting shaft. The rotor support member includes a tubular portion having a tubular shape extending in the axial direction and fitted to an outer peripheral surface of the connecting shaft. Movement of the connecting shaft to the first axial side relative to the tubular portion is restricted.
