PROBLEM TO BE SOLVED: To simplify terminal processing of a rotary electric machine, and to miniaturize the rotary electric machine.SOLUTION: A stator cover (4) attached to a stator of a rotary electric machine comprises: an inner surrounding wall (10) and an outer surrounding wall (20) that respectively corresponds to the respective parts of an internal cylinder and an external cylinder that are coaxial cylinders; and a coupling wall (30) coupling the inner surrounding wall and the outer surrounding wall with each other. On at least any one of the outer surrounding wall, the inner surrounding wall, and an outer wall surface of the coupling wall, wire connection part housing holes (21a to 21c) where wire connection parts between terminal lines led from a coil of the stator and lead wires for supplying a current to the terminal lines are housed, are provided. The coupling wall is provided with an auxiliary wall (31) in a circumferential direction. By the auxiliary wall, the inner surrounding wall surface of the outer surrounding wall, and the outer surrounding wall of the inner surrounding wall, a plurality of grooves (32a-32c) in which the terminal lines and the lead wires are installed are formed. 【課題】回転電気機械の端末処理を簡略化し、かつ回転電気機械の小型化を図る。【解決手段】回転電気機械のステーターに取り付けられるステーターカバー（４）は、同軸円筒である内筒及び外筒のそれぞれの一部にあたる内周壁（１０）及び外周壁（２０）と、該内周壁と該外周壁とを連結する連結壁（３０）とを有し、前記外周壁と前記内周壁と前記連結壁の外壁面との少なくともいずれかには、前記ステーターのコイルから引き出される端末線と、該端末線に電流を供給するリード線との結線部が収納される結線部収納穴（２１ａ〜２１ｃ）が設けられ、前記連結壁に周方向に補助壁（３１）が設けられ、該補助壁と前記外周壁の内周壁面と前記内周壁の外周壁面とにより、前記端末線及び前記リード線が設置される複数の溝（３２ａ〜３２ｃ）が形成されることを特徴とする。【選択図】図３
