Abstract

　出力軸1 と入力軸2とは、外部にモータロータ30を配した連結部材40を介して連結されている。入力軸2と連結部材40との第１スプライン結合部81には、モータハウジングMHの上壁部に形成した油供給口11aから流下した油の一部が、モータハウジングMHに固定された軸受フランジ59の開口52、空間部54を通って供給される。第１スプライン結合部81を潤滑した油は、連結部材40の回転に伴う遠心力によって中空孔45の内周面に沿って移動し、連結部材40の一端部において連結部材40の一端部側の端面に沿ってラジアル方向に移動して、出力軸1と連結部材40との第２スプライン結合部82に供給される。これにより、ハイブリット型エンジンの出力軸と油圧ポンプの入力軸とをスプライン結合させる連結軸部の両端部における二つのスプライン結合部に対して、十分な潤滑油の供給を行えるパワーユニットが提供できる。
