A vehicle drive device configured with an input member coupled to an internal combustion engine, a rotary electric machine, an output member coupled to wheels, and a power transfer mechanism that drivably couples the input member, the rotary electric machine, and the output member. An oil collecting portion is configured to collect oil supplied by rotation of the power transfer mechanism, The collected oil falling passage is configured to cause the oil collected by the oil collecting portion to flow downward to be supplied to a portion of a facing wall surface located above a cylindrical member. A communication oil passage communicates between the gap and the inside housing space is formed at a portion of abutment between the subject support bearing and the support projecting portion. |

1. A vehicle drive device comprising:
an input member drivably coupled to an internal combustion engine; a rotary electric machine, an output member drivably coupled to wheels; a power transfer mechanism that drivably couples the input member, the rotary electric machine, and the output member; and a case that houses at least the power transfer mechanism, wherein the power transfer mechanism includes a cylindrical member and an inside gear mechanism, the inside gear mechanism meshes with internal teeth provided on an inner circumferential surface of the cylindrical member, and is housed in an inside housing space formed on a radially inner side of the cylindrical member, the cylindrical member is rotatably supported from the radially inner side by two support bearings disposed on both sides in an axial direction across the inside gear mechanism, the case includes a support wall portion, and an oil collecting portion and a collected oil falling passage are provided inside the case, the support wall portion includes a facing wall surface that faces an axial end surface of the cylindrical member via a gap and that extends to a radially outer side of the cylindrical member, and a support projecting portion formed on the radially inner side of the cylindrical member so as to project from the facing wall surface toward the cylindrical member, the support projecting portion abuts against a subject support bearing, which is one of the support bearings located on a facing wall surface side, to support the subject support bearing at least from the radially inner side, the oil collecting portion is disposed above the cylindrical member, and configured to collect oil supplied by rotation of the power transfer mechanism, the collected oil falling passage is configured to cause the oil collected by the oil collecting portion to flow downward to be supplied to a portion of the facing wall surface located above the cylindrical member, and a communication oil passage that communicates between the gap and the inside housing space is formed at a portion of abutment between the subject support bearing and the support projecting portion. |
