To efficiently cool a motor part.SOLUTION: A lubrication oil supply structure includes: an oil passage (50) which is disposed along an axis direction of a motor part at a position above a stator (24) and has at least one oil hole (59) which discharges a lubrication oil pumped by an oil pump in a radial direction; and a lubrication oil guide part (7) which guides the lubrication oil discharged from the oil hole (59) to a coil end (26e) of the stator. The lubrication oil guide part (7) includes an oil receiving chamber (71) which receives the lubrication oil discharged from the oil hole (59).SELECTED DRAWING: Figure 3
【課題】モータ部の冷却を効率的に行うこと。【解決手段】潤滑油の供給構造は、ステータ(24)よりも上方位置においてモータ部の軸線方向に沿って配置され、オイルポンプにより汲み上げられた潤滑油を径方向に吐出する少なくとも1つのオイル孔(59)を有するオイル通路(50)と、オイル孔(59)から吐出した潤滑油をステータのコイルエンド(26e)に導く潤滑油案内部(7)とを備える。潤滑油案内部(7)は、オイル孔(59)から吐出された潤滑油を受けるオイル受け室(71)を含む。【選択図】図3
