PROBLEM TO BE SOLVED: To provide a power device having a function for positioning a flow channel of a liquid medium pumping device and a flow channel of a housing, and capable of suppressing leakage of a liquid medium from mating surfaces of these flow channels.SOLUTION: In a rear wheel driving device, a housing-side discharge path as an oil discharge path 95 formed on a cover member 72 and a pump-side discharge path as an oil discharge path 95 formed on an electric oil pump 70 are connected. Further the rear wheel driving device includes knock pins 121 fitted into a housing-side suction path and a pump-side suction path to regulate relative positions of the housing-side suction path and the pump-side suction path in a mounted state, knock pins 122 fitted into the housing-side discharge path and the pump-side discharge path to regulate relative positions of the housing-side discharge path and the pump-side discharge path, and a bolt 120 for relatively fixing the cover member 72 and the electric oil pump 70.
【課題】液状媒体圧送装置の流路と筐体の流路とをそれぞれ位置合わせする機能と、これら流路の各合わせ面からの液状媒体の漏出を抑制することができる動力装置を提供する。【解決手段】後輪駆動装置では、蓋部材72に形成されたオイル吐出路95である筐体側吐出路と、電動オイルポンプ70に形成されたオイル吐出路95であるポンプ側吐出路と、が接続される。また、後輪駆動装置は、前記取付状態において、筐体側吸入路及びポンプ側吸入路に嵌入されて、筐体側吸入路及びポンプ側吸入路の相対位置を規制するノックピン121と、筐体側吐出路及びポンプ側吐出路に嵌入されて筐体側吐出路及びポンプ側吐出路の相対位置を規制するノックピン122と、蓋部材72と電動オイルポンプ70とを相対固定するボルト120と、を備える。【選択図】図10
