To increase a resonance frequency of a driving unit in which a rotary electric machine is used.SOLUTION: A rotary electric machine comprises: a stator and a rotor; and a first case housing the stator and the rotor. The first case includes: a housing with one end side in an axial direction being open; and a cover fixed to the housing so as to fix the stator and cover the one end side of the housing . The cover includes an annular rib projecting from an inner face toward the other end side of the housing, and the annular rib has a plurality of boss parts to which a bolt for fastening the stator threadedly engage at intervals in a peripheral direction.SELECTED DRAWING: Figure 3

    【課題】回転電機が用いられる駆動ユニットの共振周波数を高くする。【解決手段】ステータおよびロータと、ステータおよびロータを収容する第1ケースとを備える回転電機において、第1ケースは、軸方向における一端側が開口されたハウジングと、ステータが固定されると共にハウジングの一端側を覆うようにハウジングに固定されるカバーとを有し、カバーは、内面からハウジングの他端側に向かって突出する環状リブを有し、環状リブには、ステータを締結するためのボルトが螺合される複数のボス部が周方向に間隔をおいて形成されている。【選択図】図3
