Abstract
PROBLEM TO BE SOLVED: A lubrication structure of a power transmission apparatus is provided with a lubricating liquid transport pipe for cooling a rotating electrical machine used to allow a lubricated member positioned axially outwardly of the rotating electrical machine to be lubricated in the axial direction. SOLUTION: A lubrication structure comprises an oil pipehaving discharge nozzlespositioned vertically above coil endsand discharge nozzlesaxially outwardly of the discharge nozzlein juxtaposed relationship with each other at the other axial end portion of the oil pipe, and a guide memberradially extending between the discharge nozzlesin the axial direction of a motor M and having a radially inner peripheral portion covering bearings. The guide memberhas a guide rib extending axially outwardly of a flange portionto guide the oil discharged from the discharge nozzlein the axial direction. A coverhas a cylindrical portioncovering the upper surface of a bearing. The cylindrical portionis formed with an oil passagefor guiding the oil guided by the guide ribto one axial end portion B of the bearing
