Patent ID: 8508090

Claim:
A lubrication structure of a power transmission apparatus, provided in a power transmission apparatus comprising a rotating electrical machine accommodated in a case having a rotatable rotor, a stator having a stator core provided to surround the rotor, and coil ends axially outwardly projecting from both axial ends of the stator core; a first lubricated member positioned in a neighborhood of the rotating electrical machine in an axial direction of the rotating electrical machine; and a second lubricated member positioned axially outwardly of the first lubricated member, to supply lubricating liquid to the first and the second lubricated members, further comprising: a lubricating liquid transport pipe having a first discharge nozzle provided above the rotating electrical machine and at least vertically above the coil ends to transport the lubricating liquid from one axial end to the other axial end in the axial direction, and a second discharge nozzle and a third discharge nozzle provided axially outwardly of the first discharge nozzle in juxtaposed relationship with each other; and a guide member provided between the second discharge nozzle and the third discharge nozzle in the axial direction of the rotating electrical machine to radially extend and having a radially inner peripheral portion covering an upper surface of the first lubricated member; the guide member having a guide rib axially outwardly extending from the guide member to guide the lubricating liquid discharged from the third discharge nozzle in the axial direction, the case having a cover portion covering an upper surface of the second lubricated member, and the cover portion being formed with a case oil passage for guiding the lubricating liquid guided by the guide rib to one axial end portion of the second lubricated member.
