PROBLEM TO BE SOLVED: To suppress the occurrence of electro-corrosion in members on a closed circuit including a rotor shaft, on a closed circuit including an inner peripheral side rotary shaft and on a closed circuit branched from these closed circuits collectively by means of a common insulation part.SOLUTION: A motor enclosure 10 comprises: an oil pump body 62 supporting an oil pump drive shaft 48 and a first rotor shaft 32; and an insulation gasket 92 insulating the oil pump body 62 and a trans-axle case 51. Therefore, the first rotor shaft 32 and the oil pump drive shaft 48 of which the shaft voltages are to rise are insulated from the trans-axle case 51 by the insulation gasket 92. Thus, the occurrence of electro-corrosion in the members on the closed circuits including the first rotor shaft 32 or the oil pump drive shaft 48 and the trans-axle case 51 and on the closed circuit branched from these closed circuits is suppressed collectively by the common insulation gasket 92.SELECTED DRAWING: Figure 2

    【課題】ロータ軸を含む閉回路上、内周側回転軸を含む閉回路上およびそれらの閉回路上から分岐した閉回路上の部材における電食の発生を共通の絶縁部で一挙に抑制する。【解決手段】電動機格納装置10は、オイルポンプ駆動軸48と第1ロータ軸32とを支持するオイルポンプボデー62と、オイルポンプボデー62とトランスアクスルケース51との間を絶縁する絶縁ガスケット92とを、備える。このため、軸電圧の上昇する第1ロータ軸32およびオイルポンプ駆動軸48が、絶縁ガスケット92によりトランスアクスルケース51に対して絶縁される。これにより、第1ロータ軸32またはオイルポンプ駆動軸48とトランスアクスルケース51とを含む閉回路上、およびそれらの閉回路上から分岐する閉回路上の部材における電食の発生が共通の絶縁ガスケット92で一挙に抑制される。【選択図】図2
