The invention relates to a dynamo-electric machine, and a drive device for a vehicle comprising the dynamo-electric machine. When a case for this dynamo-electric machine has an inner case member for containing a stator and also has an outer case member for containing the inner case member, vibration transmitted from the stator through the inner case member to the outer case member is suppressed. An inner case member (1) is provided with a first cylindrical section (11) and a first protrusion section (13) which protrudes on the axial first side (L1) from the first cylindrical section (11) toward the radially inner side (R2). The outer case section (2) is provided with a second cylindrical section (12) and a second protrusion section (14) which protrudes on the axial first side (L1) with respect to the first protrusion section (13), from the second cylindrical section (12) toward the radially inner side (R2). A refrigerant flow passage (16) is formed between the first cylindrical section(11) and the second cylindrical section (12), and the first protrusion section (13) and the second protrusion section (14) are affixed to each other.
本发明涉及旋转电机以及具备旋转电机的车用驱动装置。在旋转电机的壳体具有收纳定子的内侧的壳体部件、和收纳内侧的壳体部件的外侧的壳体部件的情况下,抑制从定子经由内侧的壳体部件向外侧的壳体部件传递的振动。内侧壳体部(1)具备第一筒状部(11)、以及在轴向第一侧(L1)从第一筒状部(11)向径向内侧(R2)突出的第一突出部(13),外侧壳体部(2)具备第二筒状部(12)、以及相对于第一突出部(13)在轴向第一侧(L1)从第二筒状部(12)向径向内侧(R2)突出的第二突出部(14)。在第一筒状部(11)与第二筒状部(12)之间形成制冷剂流路(16),第一突出部(13)与第二突出部(14)被相互固定。
