To reduce occurrence of electric corrosion by suppressing reduction in an insulation performance of an insulation member between a case and a support member even if a projection is present on a surface of the case or the support member in a vehicular motor storage device.SOLUTION: A vehicular motor storage device 10 comprises: a rear cover 52 that is a constituent of a case in which a motor is stored; an oil pump body 62 that is a support member for supporting a first rotor shaft 32 of the motor in a rotatable manner; and an insulation member 200 which insulates between the rear cover 52 and the oil pump body 62. The insulation member 200 includes an insulation layer 110, a rear cover side protection layer 120 and an oil pump body side protection layer 130. The rear cover side protection layer 120 and the oil pump body side protection layer 130 are disposed between the insulation layer 110 and at least one of the rear cover 52 and the oil pump body 62 facing the insulation layer 110, and have a higher strength than that of the insulation layer 110.SELECTED DRAWING: Figure 3

    【課題】車両用電動機格納装置において、ケースや支持部材の表面に突起物が存在したとしても、ケースと支持部材との間の絶縁部材の絶縁性能の低下を抑制して電食の発生を低減させる。【解決手段】車両用電動機格納装置10は、電動機を格納するケースの構成部材であるリヤカバー52と、電動機の第1ロータ軸32を回転可能に支持する支持部材であるオイルポンプボデー62と、リヤカバー52とオイルポンプボデー62との間を絶縁する絶縁部材200と、を備える。絶縁部材200は、絶縁層110、リヤカバー側保護層120、およびオイルポンプボデー側保護層130を含み、リヤカバー側保護層120、オイルポンプボデー側保護層130は、絶縁層110と絶縁層110に対向するリヤカバー52およびオイルポンプボデー62の少なくとも一方との間に配置され、且つ絶縁層110よりも高強度である。【選択図】図3
