First Claim
1. A vehicle drive device, comprising:
- a rotating electrical machine having a rotor that rotates about a central axis;
a case accommodating the rotating electrical machine; and
an oil passage provided in the case to supply oil to a predetermined element to be supplied with an oil pressure, whereinthe case has a support wall that extends at least radially, and an axially protruding portion that is cylindrically shaped and formed integrally with the support wall and protrudes axially from the support wall toward the rotating electrical machine,a rotor support member that extends at least radially to support the rotor is supported radially and axially so as to be rotatable with respect to the axially protruding portion via a support bearing that is provided on an outer peripheral surface or an inner peripheral surface of the axially protruding portion,the element to be supplied with the oil pressure is positioned on a side axially opposite to the support wall with respect to the rotor support member, and an accommodating member that accommodates the element to be supplied with the oil pressure is positioned axially in contact with the rotor support member,the vehicle drive device includes a supply oil passage to the element to be supplied with the oil pressure, which is provided inside the support wall and the axially protruding portion, andthe supply oil passage has an end face opening that is formed in an end face located in a protruding direction of the axially protruding portion.

Abstract
A vehicle drive device, having a case with a support wall that extends at least radially, and an axially protruding portion that is cylindrically shaped integrally with the support wall and protrudes axially from the support wall toward a rotating electrical machine. A rotor support member is supported radially and axially so as to be rotatable with respect to the axially protruding portion via a support bearing provided on an outer or inner peripheral surface of the axially protruding portion. The element to be supplied with the oil pressure is positioned on a side axially opposite to the support wall. The vehicle drive device includes a supply oil passage, which is provided inside the support wall and the axially protruding portion, and has an end face opening that is formed in an end face located in a protruding direction of the axially protruding portion.
