Abstract: A friction engagement device includes an elastic member between a piston and a friction plate in an axial direction. Elastic member includes: second engaged portion to be brought into engagement with engagement portion of tubular member so as to be movable in axial direction; and annular plate portion sandwiched between pressing surface of piston and friction plate from both sides in axial direction. Surface of annular plate portion facing first axial side is provided with projection and recess arranged alternately in circumferential direction. Assuming that a phase where radial groove provided in pressing surface and projection provided on annular plate portion are located at corresponding positions in circumferential direction is a particular phase, engagement portion of tubular member, first engaged portion of piston, and second engaged portion of elastic member are formed such that piston and elastic member are unable to come into engagement with tubular member at particular phase.

Abstract: 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.

Abstract: 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.

Abstract: A rotating electric machine includes a case, a stator, a first rotary member including a rotor core and a first shaft, a second rotary member including a second shaft, and a multiple disc clutch. A first oil passage and a second oil passage are provided inside the case. The first oil passage starts from an inside of the first shaft or an inside of the second shaft, passes through the multiple disc clutch from an inner side to an outer side in a radial direction with respect to a rotation center, and reaches an inner side of the rotor core in the radial direction. The second oil passage starts from the inside of the first shaft or the inside of the second shaft and reaches the inner side of the rotor core in the radial direction without passing through the multiple disc clutch.
