Rotor for rotary electric machine and vehicle drive device including the rotor for rotary electric machine

A rotor for a rotary electric machine, the rotor comprising:

• a rotor core;
• a rotor shaft having a tubular shape, passing through a radially inner side of the rotor core to be coupled to the rotor core, and extending along an axial direction;
• an oil supply path that supplies oil to the rotor shaft,
• a portion to be lubricated that is disposed on a first axial side with respect to the rotor core, wherein one side in the axial direction is defined as the first axial side and another side in the axial direction is defined as a second axial side;
• and
• a lubrication oil path through which oil is supplied to the portion to be lubricated, wherein:
• the rotor shaft includes:
• an inner peripheral portion surrounded by an inner peripheral surface of the tubular shape,
• a radial oil path that has an opening that opens in the inner peripheral surface and that extends along a radial direction,
• an annular weir disposed on the first axial side with respect to the opening and disposed so as to project radially inward from the inner peripheral surface and extend in a circumferential direction along the inner peripheral surface, and
• an axial communication path;
• the oil supply path supplies oil to a portion of the inner peripheral portion on the second axial side with respect to the weir;
• the lubrication oil path is disposed on the first axial side with respect to the weir;
• and
• the axial communication path is provided in the inner peripheral surface or the weir to communicate between a portion of the inner peripheral portion on the first axial side with respect to the weir and the portion of the inner peripheral portion on the second axial side with respect to the weir and communicate with the lubrication oil path.
